DETAILED DESCRIPTION
FIGS. 1A-1D illustrate a control cable meant to provide material control by introducing a downward tension force on the material being lifted. The control cable is threaded through the material being lifted and applies a downward tension force on the material to provide both rotation, tilt, and swing control.
FIGS. 2A-2M illustrate several embodiments of a double-sided tape measure device used to measure the length of a load. The double sided tape measure may include an under hood light and a two strap centering system. Finding the center of a material being lifted is essential for a balanced lift when the load is suspended via cable or chain. In one embodiment, each side of the double sided tape measure includes colors that correspond to different lengths. As a result, the user may match the colors of each tape measure to ensure a centered position. In some embodiments, the ends of each tape measure may include a magnet or clip to secure the ends of the tape measure to the material. The tape measure may further include an encoder that alerts the user (e.g., via visual, sound, haptic, etc.) that the tape measure is in a center position. In another embodiment, the tape measure may be spring-expandable and allow the user to place one hook into the end of a pipe and stretch over the pipe to place a second hook on the other end. The tape measure may include a sleeve that sides along rigging to find and easily adjust the center. In some embodiments, the device may include an auto-center with a 1:1 expansion rate.
FIGS. 3A-3G illustrate a hopper device configured to attach to a lifting device for providing a method for feeding a lift material up to an installer at an elevated height. The hopper is advantageous because it improves the lack of efficiency involved in the “stick-by-stick” installation process. Additionally, the hopper can be adaptable to be used with or without a scissor lift in tandem. The hopper may be positioned relative to a work space to elevate pipe from a lower surface (e.g., the ground) to an elevated surface (e.g., a cab of a scissor lift) or vice versa. The hopper includes a carrier that may be controlled by the user (e.g., wirelessly, wired control, etc.). The carrier may repetitively ascend and descend to allow the user to remain at an elevated workspace. In one embodiment, the hopper may include a carrier portion that is movably along an elongated body of the hopper. The carrier moves along the elongated body of the hopper to supply pipes to the user's elevated workspace. The user's workspace may be a scissor lift cab. In some embodiments, any combination of scissor jacks, mini lifts, articulating arms, or platform rollers may be positioned within or formed on the user's workspace to assist the user during movement of the pipe. For example, scissor jacks may be mounted on front or back rails of a scissor lift, a mini lift may be positioned within the lift cab, an articulating arm may be mounted on the scissor lift rail or to framing, and/or platform rollers may be formed on the rails of the scissor lift or positioned within the user's workspace. As a result, the user may maneuver the pipe (e.g., by pushing/pulling the pipe), while the bulk of its weight is being supported by one or more of the scissor jacks, the mini lift, the articulating arms, or the platform rollers.

FIGS. 9A-9H illustrate a remote hoist lift including an extendable ground hoist having a powered hoist mounted on the ground hoist that can selectively perform lifts in response to actuation from a remote. The remote hoist may include a cable and a securing device (e.g., a hook, a securing device as described in Paragraph 28 below, etc.) that is adjustable to secure a desired material such as a pipe to the securing device. The remote hoist allows the user to control the position and height the pipe is elevated to from a remote location. The remote hoist may be used with a rotating trolley that includes a boom having a trolley, an overhead conveyor, and a 3-joint dual hoist rotating jib. The rotating trolley is capable of rotating 360 degrees around a mast axis and the trolley may move along the boom. As a result, the pipe may be elevated and translated to a desired position. In another embodiment, the remote hoist may be used with a duct jack platform having a base with wheels so the platform is movable within a desired area. The platform includes a vertical support post and a mounting portion that extends transversely from the support post. The mounting portion includes a mounting post that extends from a distal end of the mounting portion to support the remote hoist. In yet another embodiment, the remote hoist may be used with a platform that includes a vertical support post and a cross beam that extends transversely from the vertical support post. The remote hoist is connected to a distal end of the cross beam. In yet another embodiment, the remote hoist may be used with a platform that includes a vertical support post and an overhead track conveyor that extends transversely to the support beam. The remote hoist may be attached to a trolley that is operably coupled to the track conveyor. As a result, the hoist may smoothly roll along the track conveyor so the pipe supported by the remote hoist may translate in an outward direction from the support beam along the track conveyor. In yet another embodiment, the remote hoist may be used with a three-joint rotating jib with a tee. The rotating jib includes a vertical support post and three swivel joints that allow for rotation about the vertical support post, and a mounting portion. Two independent remote hoists are attached to the mounting portion to control a lifting operation of the pipe. The independent remote hoists allow for tilting maneuvers of the pipe during the lifting operation.

In one embodiment, the platform may include a conveyor roller v-groove to assist in the movement of the pipe. In some embodiments, the support surface may further include slides that extend both outward and laterally. As a result, the user may translate the pipe on the support surface in any direction.
FIGS. 63A-63B illustrate a rotating trolley for use with a remote hoist system. The remote hoist system includes a boom having a trolley, an overhead conveyor, and a 3-joint dual hoist rotating jib. The trolley is capable of rotating 360 degrees around a mast axis to a desired position.
FIGS. 64A-64B illustrate an extendable boom system to be used with a powered roustabout. The boom can extend and retract while simultaneously supporting a load.
FIGS. 65A-65C illustrate a tilt/turn system utilizing a powered duct jack. The tilt/turn system can include a platform for supporting a lift material that can lift, tilt and/or rotate the lift material.
FIGS. 66A-66B illustrate a tensioning system utilizing a winch control system. The tensioning system allows the user to control and maneuver a lift material mid-air with powered winches while maintaining constant tension between the lift material and the control system. The winch control system allows users to both control and maneuver a pipe with powered winches. More specifically, the system uses counter-tension from the ground in order to control the pipe during the lift. Because the downwards tension is actively controlled (e.g., powered), the user can not only prevent unwanted movement but they can also adjust the tilt of the pipe with the push of a button.
FIGS. 67A-67B illustrate a coordinated winch system utilizing a winch control system. The coordinated winch system allows multiple winch units to be oriented in various combinations depending on a lift material's placement (long run unit, or difficult to reach location).
FIGS. 68A-68F illustrate a set of slings. Each sling may include a securing region that is wrapped around a desired material (e.g., a pipe) and two loop regions positioned at each end of the sling. When the sling is secured to the pipe, one loop region extends upward from the pipe and may be attached to a lifting hook to lift the pipe. The loop region that extends upward from the pipe may be various colors (e.g., red, green, blue) to indicate the respective length of each sling (e.g., each color corresponds to a length). As a result, when a user is able to determine the length each sling by the color of the sling, rather than having to check a small label. Additionally, the slings may include a label that denotes the pipe diameters with which each sling works best. For example, the label on each sling indicates with which pipe diameters each sling should be used to minimize the amount of excess sling/overhead during operation
FIGS. 69A-69E illustrate a belt syncher including a sling having two loop regions positioned at each end of the sling, a D-ring or cam buckle, and a plurality of grommets positioned at different locations on the sling. The belt syncher does not choke around the pipe, but rather synchs down using the D-ring and grommets. As a result, the user can quickly wrap the sling around any size pipe, slide the sling through the D-ring, and synch the pipe using the D-ring and grommets. This allows the user to minimize the overhead of the sling during lifting.
FIGS. 70A-70F illustrate a belt choker including a sling having two loop regions positioned at each end of the sling, a D-ring or cam buckle, and a plurality of grommets positioned at different locations on the sling. The user may insert one end of sling through the D-ring or cam buckle and adjust the length of the choker to conform with the diameter of the pipe being lifted. The grommets allow the user to take up an excess portion of the sling to limit the overhead of the sling. As a result, the user can quickly secure the sling to any size pipe without having to wrap the sling around the pipe to limit the overhead of the sling.
FIGS. 71A-71E illustrate a cam lock choker device including a sling having two loop regions positioned at each end of the sling and a cam lock attached to the sling. In the illustrated embodiment, the cam lock is directional, so the slack of the sling can be pulled through the cam lock easily to tighten the sling around pipe. However, the sling cannot be pulled back through (e.g., to loosen) the cam lock unless a cam lever is pressed. As a result, the user is able to quickly choke any size pipe and then synch up the excess material of the sling through the cam lock.
FIGS. 72A-72D illustrate a multi-loop sling including a sling having two loop regions positioned at each end of the sling and a plurality of loops formed along the length of the sling. One end of the sling may be inserted through one of the plurality of loops to choke a pipe being lifted. As a result, the user is able to form a choke around any size pipe without having to wrap the sling around the pipe multiple times. Additionally, the user may adjust the overhead section of the sling by changing the loop through which the one of end of the sling is inserted.
FIGS. 73A-73E illustrate a mobile application utilizing a mobile device to determine optimal lifting location(s) on a material/load being lifted. The mobile application may be used with a mobile device to determine the optimal lifting location(s) on a pipe being lifted. In the illustrated embodiment, the user may take a picture of the pipe on a mobile device and the mobile application calculates attachment position(s) on the pipe that the users should place a lifting sling(s) to perform a level lift. For example, mobile application may estimate the visual center point of the pipe and attachment position(s) of the lifting sling(s) based on the profile of the pipe. As a result, the mobile application decreases the amount of time required to perform a level lift and allows the user to double check the attachment position(s) of the lifting sling(s).
FIGS. 74A-74E illustrate a trigger clamp and leveler device including a plurality of trigger clamps connected to a leveling mechanism. The trigger clamp and leveler device may include two trigger clamps connected to a leveling mechanism. As a result, the device includes two points of contact with a pipe when the user lifts the pipe and allows the user to alter the balance of the pipe in-air (e.g., during lift) as needed. The trigger clamps allow the user to clamp the pipe from above so the pipe does not need to be raised or shimmed before the device engages with the pipe to perform a lift. In the illustrated embodiment, the clamps are adjustable to allow pipes with nominal pipe diameters between 1.5 inches to 6 inches to be lifted. To attach a pipe to the device, the user may place the two trigger clamps over the pipe and repeatedly pump a trigger of the clamps to tighten the clamp around the pipe. In some embodiments the leveler may include an acme screw coupled to a handle to allow the user to adjust the height of one end of the pipe (e.g., raise or lower) to level the pipe in-air. In other embodiments, a power tool and a level with an electric readout may be coupled to the leveler to allow the leveler to automatically level the pipe in-air.
FIGS. 75A-75D illustrate a gravity clamp device including a pivoting lever arm that may be adjusted to lift a lift material (e.g., a pipe) with a nominal diameter between 2 and 6 inches. The gravity clamp device may include a pivoting lever arm that may be adjusted to lift pipes with a nominal diameter between 2 and 6 inches. The device further includes stabilizing wings that allow a small angle tipping motion of the pipe during lifting. The pivoting lever arm is adjustable to different diameters of pipe before attaching to the pipe. During operation of the device, the user may place the unit on top of the pipe and the pivoting lever arm will clamp around the pipe to securely lift the pipe in one swift motion.
