When a home or building is constructed there are usually pre manufactured trusses that are shipped to the job site instead of the workmen building them by hand on the job site because the trusses can be manufactured in a very economical fashion. The truss builders use a plate that has slots stamped into it where as the slots are only cut with an opening on one end, the other end bends making fingers that when pressed on to several pieces of wood, joins those pieces together creating a very substantial bond or union with great holding strength and since trusses sometimes are of the same size and shape, these can be manufactured and shipped in a very cost effective manner. Many homes and building today use pre manufactured trusses.
However when the trusses are in large number and are on the ground at the job site they usually must be lifted by a large crane with a boom in order to place them in the proper sequence and at the proper location on the walls or roof of the building.
The usual manner of lifting the trusses is to have a workman stand by the stack of trusses, and when the crane operator swings the boom around there is attached to the boom, via a cable or rope a hook that the workman attaches to a single truss, beam or what ever object is being installed on the building. Then the crane operator lifts the one truss up and at the same time swings the boom to where two or more workmen are on the walls, usually one on each side and at least one is in the middle, depending on the size of the truss or object and the one in the middle installs a bar of predeteimined length between each of the trusses that holds the top of the trusses from tilting forwards or backwards. Then, the other workmen on the walls attach the ends of the truss to the top of the walls or roof, then, the man in the middle releases the lifting strap(s).
Then the crane operator is signaled to swing the boom back over to the workman on the ground where he attaches another single truss to the strap(s) and the operation is repeated until all the trusses are installed on the walls or roof creating a roof or other structure(s).
Since only one truss in lifted and installed on the walls or roof of the building at a time, a great deal of time is lost in man labor waiting for the next truss to be brought up.
All the time a worker is usually standing on the ground or on the truck waiting for the truss to be installed and the boom and strap to be swung back for him to attach the next truss.
This is an enormous waste of time. There is a need for a multi strap truss lifter that is forgiving in nature, that can compensate for the wide variety of shapes and sizes of trusses, that can be safely and quickly attached to and lift multiple trusses at a time, saving on man hours, lowering the number of men needed for the job and eliminate a great deal of the time the crane is rented and is swung back and forth for each individual truss.
It would be possible for one worker, with the aid and assistance of this novel invention, to attach multiple trusses on to a single, main line, or set of lines and that same worker could now climb up on to the walls or roof and install multiple trusses in one setting, cutting the fatigue and time of climbing up and down the walls or roof for each truss or having an individual waiting by the trusses in order to install each one after the previous one is installed and saving the time that the crane operator spends swinging the boom back and forth.
METHOD
The crane operator would have the workman lay the straps on the trusses next to the balance point of each truss, then, with the hooks between the main strap and the trusses, the workman would attach the hooks to the trusses in reverse order that the trusses are to be installed on the walls or roof, then he attaches the first truss strap that is highest on the main strap first, because this truss is going to be set into place on the wall or roof last, in other words, the first truss picked up by the main strap will be suspended the highest on the main strap after all the trusses are suspended in the air. Then the workman attaches the next strap that is next in line and lower on the main strap, to the next truss that will be the second to the last to be, installed on the walls or roof.
This procedure is repeated until all of the trusses are attached, so that the last truss attached to the main strap is the lowest hanging and the first to be lowered on to the walls or roof and installed.
So when a crane operator swings the boom over to the trusses, he has a workman attach the main strap hook or ring to the crane hook,
The trusses will be vertically pivotal, with or without a bearing, so that the trusses suspended on up the line will be away from or on the other side of the lowest hanging truss or item, then the first truss is lowered into position, it is attached to the walls or roof then the next truss is lowered all the way down on to the walls or roof with the workers positioning the next truss into place as it is being lowered, keeping the previously set truss between the workers and the trusses that is being lowered and set into position so that the trusses still in the air, would not be over the head of the installers on the walls or roof, or the installers on the top of the trusses, setting the top of the trusses.
Then the workers would step over or through the truss that is already attached to the walls or roof to finish attaching the next truss that has just been lowered on to the walls or roof. Then the crane operator lowers the next truss down on to the walls or roof, that is already in the air over the walls or roof, makes a slight adjustment to the boom so as to properly position the truss on to the walls or roof, and lowers the next truss all the way down, on to the top of the walls or roof, with out having to;
- 1. Raise the straps up,
- 2. Swing the boom back over to where the other trusses are still on the ground or truck,
- 3. Have another worker attach the next truss, or have a worker that is on the walls or roof come down and attach the next truss on to the line, then, have that worker climb back up on the walls or roof,
- 4. Raise the next truss,
- 5. Swing the boom over to where the next truss needs to be installed,
- 6. Lower the next truss in place and or among other things.
The multi attaching, lifting and installing of the trusses on to the walls or roof would be repeated till all are installed on the building.
The hooks on the main line would be on the same side or both sides of the main line(s), in any arrangement depending on the need;
Or the main line would not have hooks but would have attachment points that auxiliary straps would be attached to;
The one end of the auxiliary straps would be attached to a main line attachment point; where as the other end of the auxiliary straps would be attached to the trusses or items.
At times, multiple straps would be used on each truss because of large or odd shapes where the balance point of the truss would or would not be off set, these straps would be of different lengths and sizes, in any arrangement or combination as the need may be.
After the truss has been set and fastened to the walls or roof, there would or would not be a place for the hooks that have been removed from the trusses to be attached to, either on the main or auxiliary straps. There would or would not be a covering or shield to cover the stored hooks so that when the crane operator is finished with any given set of trusses and he picks the lines up for another set or the job is done, the hooks would not become entangled, or get caught on any of the trusses and they would be out of the way of the truss installers.
In another embodiment of this invention, the individual auxiliary straps would be “detachable” from the main strap. The main strap attachment points would be either hooks, rings or loops, devises or any other attachable arrangement and the auxiliary strap end that attaches to the main strap would be a hook, ring or loop to attach itself on to the main strap attachment point, either to be removable or replaceable for other types of straps with any attachable device, but also to be removed to be out of the way so as not to become entangled on the trusses or rafters or any other item after these items have been installed on the building.
The main strap would be removable from the crane hook. Any detachable straps, after they have done their job, either the main strap with all the auxiliary straps attached to it or just the auxiliary straps would be passed down to the ground workman to attach to the next set of trusses. Then while the installers are attaching the remaining trusses to the walls or roof, these straps or another set of straps can be attached to another set of trusses to save time so that when the first load is finished being installed and affixed on the walls or roof, all the crane operator needs to do is swing the boom around for another load and have these immediately attached to the crane hook.
In another embodiment of this invention, the auxiliary straps would or would not also have multiple attachment points on them and or, both ends would terminate in a hook, loop, ring or any other attachable arrangement so that other straps weather they be main or auxiliary straps, could be attached to them as the need may be.
In another embodiment of this invention, the main strap would have a ring or hook on one or on both ends, so that additional main straps with other auxiliary straps, coming off of it, could be added when needed to lift larger numbers of trusses at one time and at times, a plurality of trusses or items would be attached to any one or multiple set of straps.
The hooks at any location on any of the straps would be large enough to hook on to the apex or balance point or any other attachment points of the trusses or be made in such a way that the hook and strap would be passed under or through the truss, at the most advantageous location on the trusses, and then the hook would be attached to its own or any other line, forming a loop with safety devices to hold the hooks in place till the workmen physically removes them.
In another embodiment of this invention, the hook would be in the form of a large hook, or clamp. If a clevis is used the pin would be pulled out or unscrewed and removed in order for the workman to attach the clevis and strap to the trusses, in any arrangement and then be removable after the trusses or items are affixed to the walls or roof.
The straps, when there would be all on one main strap arrangement, single or plural for each length, or multiple straps on a main ring, each strap would have a number, color or texture or any combination thereof for the worker to distinguish the correct order of sequence that the trusses or any other items would be in, in order to have them in correct alignment, orientation and or sequence when they are in the air suspended over the walls or roof and when they are lowered, the correct truss would be in position to be installed and affixed at the correct place on the walls or roof.
In another embodiment of this invention, there would be a main ring, with multiple straps, at least one for each truss. Each strap or set of straps would be of a different length for each consecutive truss, lifting at least one truss for each strap or set of straps. Also the straps sometimes would be adjustable as to length as the case may be needed and at times the straps would have an elastic characteristic to them to help balance the amount of weight each strap would carry and make handling the trusses easier for the installers because they would be able to shift or rock them from side to side as needed to align them to the walls or roof. In this configuration, each strap would be single or multiple, and anywhere along its length, there would or would not be attachment points for additional main or auxiliary straps, in any combination or configuration.
In one embodiment of this invention, there would be a swivel between the hook on the crane and the straps, which ever straps they may be so that the trusses could be turned or oriented to the wall or roof and the last truss picked up, which would be the one hanging the lowest on the main line or on the longest straps and in the string of trusses and would be the first to be set into place without the other trusses hanging over the head of the installers.
In another embodiment of this invention, the main strap and the auxiliary straps coming off of the main strap as well as straps coming off of the auxiliary straps, not shown, to hold large and very wide trusses or items, all these straps would be made of steel wire rope, chain links, or Kevlar or nylon or any combination there of or any other materials that would be economical and or of sufficient strength to accommodate the loads placed on it.
There are straps that have a series of loops such as a gun bullet holder where a belt or strap holds numerous bullets; however these simply hold the item for when they are needed, not to assist in installing an item in any sequence of order or for raising or lowering into place as in the case of constructing a building.
2717801 is a jig for lifting multiple rafters at one time however this rack is very unforgiving in nature because the rack would need to be reconstructed to compensate for different shapes of trusses where the inner configurations of trusses must at times, be custom designed for any particular structure, there is no guarantee that the truss shape would match the ridged racks attachment points and if the truss should shift off to one side the truss would become unstable, and if the workmen needed to pull down on one end in order to install or align the truss or member to one side, this could lift the other end of its carrier contact point, possible removing the other end from its cradle, however with straps that hook on to or wrap around the truss and are secured with safety devices incorporated into the hooks or attaching apparatuses, these would not become unhooked when, inevitably a workmen would push, pull, tilt and align either side or end to the installation point(s) they would be with out fear of the other end becoming unattached. The straps with or without length adjustability, or elasticity, would be attached to the fulcrum points or over a wide area of the truss.
Even if different lengths of straps were needed, this would prove no problem because the longer or shorter straps would only need to be attached to the main line or main ring attachment points and if there were a wind, or the trusses are bumped or jarred, the straps would be securely attached to the trusses and would not allow it to shift off to one side and the strap(s) would not become unattached until they were physically removed by the workmen.
Also, if there were some ceiling joists already installed, the rigid lifting frame would be in the way if trusses were to be installed, because the rigid frame must descend down below the previously installed rafter or truss also, there is no mention of a sequence, which is critical because in any building, all the members can be of different length, thicknesses, heights and weights or configurations and with the preferred embodiment of this invention, all can be accommodated by different locations on the main straps or on the main ring, or on different locations on the items being lifted in conjunction with the employment of any number and lengths of straps and with the availability and the capacity of adding on additional straps, different sizes of building materials can be accommodated. Also, with new types of building members that are constructed in new and novel ways as well as with new materials, longer and heaver members are being employed where any length of these items can be created according to an engineers request, to construct larger and better buildings, these member are sometimes far to large to be safely handled physically by workmen.
These also would be placed into position by the use of these lifting straps, in sequence and in multiple numbers. The auxiliary straps on the main line or ring, being single or plural would then have additional straps coming off of it, or in other words, each main or auxiliary strap would or would not have a singe or plural attachable device on one end and terminate in a single hook, ring, loop or any other attachable device on the other end or would have multiples ending straps on each of these main or auxiliary straps with any single or multiple attachable devices and there would be at least one on each side as well as the main auxiliary strap extending down, in any configuration so that the item to be installed would be held with at least one, two, three or more attachment points on each item to be installed, not shown.
6093070 id a life saving strap suspended between two lifting devices, not one and has a lifting area straight across level to the waters surface, not down, lifts all straight across, needs a third center lifting strap to hold it level, when there is a heavy load and there is no mention of dropping each on the deck one after the other and only works if there are two winching devices to pull the main strap taunt to provide the lifting means, said shackles are not hooks which cannot be wrapped around a devices and reattached to its own line creating a secure loop so that the load cannot become unattached by wind, vibration, or any other gyrations and the items are not intended to be installed in sequence.

The sixth strap, 601, in this illustration, has an extra large hook instead of a smaller hook. 11, to be attached directly to the truss with or without a loop. The straps are of different lengths and are numbered, 29, according to the length and sequence that the trusses would be attached and installed on the walls or roof, after it is wrapped around a rafter(s) (not shown) and hooked on to its own strap or directly to the trusses. Also additional straps, 36, could have an add on hook, 12 and there could be a main line, 6, with other straps attached to it, in any number or sequence and as a whole, and the ring, at times would employ any combination of different straps, 100, 101, 102, 103, 6. The longest strap would be attached to the first item that is to be installed on the walls or roof, or moved in any way with or without a sequence and the shortest auxiliary strap would be attached to the truss, rafter, or any other item to be installed with or without a sequence, that would be the last item to be installed. Also each strap would or would not have a storage loop, 27, with or without a safety cover, for storing the bottom hooks, after they have been detached from the truss, or can be attached to the main ring and stored there or left free. In this configuration, additional straps would be attached to the ring, clevis, or what ever other configuration or attaching apparatus of the member that the straps are attached to or any number would be removed as to the number of trusses there are to be installed at any given time. Also, additional straps could be added with the use of an add on extension strap, 36, that would carry the load for another set of main straps in some instances where adding on another main strap on to a main line would over stress the first main strap, thus distributing the weight over the entire ring more evenly. The, add on, extension strap would or would not have its own attachment points, 7 & 8, or be used only as an extension. The straps would be of different or equal lengths, expandable or not, to accommodate any size truss or item.
It is to be understood that this invention described herein does not limit its scope, adaptability and capabilities as many other variations can be created although not specifically mentioned here.
