The construction industry contributes significantly to many countries' gross domestic products (GDP) and thereby contributes to the economic development of the same. Currently, global expenditure on the construction industry exceeds $11 trillion a year and is expected to rise to around $14.8 trillion by 2030. Specifically, the building construction industry consists of many facets. Whether residential or commercial construction, extensive manpower is needed to complete a construction project. Residential construction may be undertaken by independent property owners, specialized construction builders, property developers, general contractors, or local authorities. Often heavy construction equipment is used, such as construction cranes for the purpose of lifting and maneuvering heavy loads.
Unfortunately, although the construction industry promotes economic development and brings many non-monetary benefits to many countries, it is one of the most hazardous industries. For example, about 20% of US industry fatalities in 2019 happened in construction. There are three serious hazards of the construction industry, in general, and crane operation, in particular, including electrocution, falls from heights, and collapsing loads. Falls are the most common causes of injuries on construction sites because they occur so often. Even if workers take all the necessary precautions to ensure a fall never happens, they still can occur because people can make mistakes or unexpected things can happen. Falls can cause serious injuries from broken bones to paralysis depending on how high the fall is and where it occurs. As to collapsing loads, these can occur whether safety precautions and proper planning have been implemented. Specifically, during the crane's operation, numerous injuries often result from maneuvering loads and/or unhooking a load from the crane hook. In particular, the crane hook must be hooked and unhooked from a forklift that carries a load of building materials. Sometimes injuries can occur including flesh wounds, broken limbs, loss of limbs and loss of life.
It is within this context that the embodiments arise.
Embodiments of gripping device for a crane hook and method of communicating open and closed status of the hook to a crane user-interface is provided. It should be appreciated that the present embodiment can be implemented in numerous ways, such as a process, an apparatus, a system, a device, or a method. Several inventive embodiments are described below.
In some embodiments, the gripping device for the crane hook is provided. The gripping device for a crane hook for safely removing a hook from a forklift may include a handle, having a trigger coupled to a cable. The gripping device may further include a central rod coupled to the handle, wherein the cable can lie seated within a central rod. A pair of jaws may couple to the central rod, having a finger coupled to one of the pair of jaws. Particularly, the cable can be coupled to the finger, wherein when the cable is pulled by the trigger, the finger pivots downward toward the latch of the crane hook to open the same. As such, when the trigger is actuated, the cable is pulled, which pulls the finger down to open the latch of the crane hook. When the trigger is released, the cable is released and the finger retracts up. The gripping device can also include a pair of magnets coupled to each one of the pair of jaws for attracting each jaw to a side of the crane hook to hold the crane hook stable. Further, the gripping device may include a sensor for detecting the open and closed status of the hook. Moreover, the gripping device may include a transceiver to communicate the open and closed status of the hook to the crane cab user-interface for the driver to be notified.
In some embodiments, a method of a crane hook open and closed state with a crane cab is provided. The method may include detecting contact between a finger of a gripping device and a latch of the crane hook. In particular, the detecting step may include sensing a first juxtapose position of a magnet of a pair of jaws of the gripping device with the crane hook. Further, the detecting may include sensing, in response to the sensed first juxtapose position, a second juxtapose position of the finger of the gripping device with the latch of the crane hook. As a result, the method may include affirming, in response to the sensed second juxtapose position, the contact between a finger of a gripping device and a latch of the crane hook exists. The method may further include indicating, in response to the detected contact, the open state of the crane hook. In the alternative, the method may include indicating, in response to absence of the detected contact, the closed state of the crane hook. Accordingly, the method may include transmitting the open and closed state to a transceiver of the crane cab; and finally, displaying the open and closed state on a display in the crane cab.
In some embodiments, a tangible, non-transitory, computer-readable media having instructions whereupon which, when executed by a processor, cause the processor to perform the crane hook open and closed state communication method described herein. The method may include detecting contact between a finger of a gripping device and a latch of the crane hook by a sensor in a client unit. In particular, the detecting step may include sensing a first juxtapose position of a magnet of a pair of jaws of the gripping device with the crane hook. Further, the detecting may include sensing, in response to the sensed first juxtapose position, a second juxtapose position of the finger of the gripping device with the latch of the crane hook. As a result, the method may include affirming, in response to the sensed second juxtapose position, the contact between a finger of a gripping device and a latch of the crane hook exists using a processor of the client unit. The method may further include indicating, in response to the detected contact, the open state of the crane hook by a transceiver of the client unit. In the alternative, the method may include indicating, in response to absence of the detected contact, the closed state of the crane hook by a transceiver of the client unit. Accordingly, the method may include transmitting the open and closed state to a transceiver of the crane cab using the transceiver of the client unit; and finally, displaying the open and closed state on a display in the crane cab coupled to the transceiver of the crane server unit.
Other aspects and advantages of the embodiments will become apparent from the following detailed description taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the described embodiments.
The described embodiments and the advantages thereof may best be understood by reference to the following description taken in conjunction with the accompanying drawings. These drawings in no way limit any changes in form and detail that may be made to the described embodiments by one so skilled in the art without departing from the spirit and scope of the described embodiments.
The following embodiments describe a gripping device for a crane hook and method of communicating open and closed status of the hook to a crane user-interface. It can be appreciated by one skilled in the art, that the embodiments may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the embodiments.
In some embodiments, the gripping device for the crane hook is provided. The gripping device for a crane hook for safely removing a hook from a forklift may include a handle, having a trigger coupled to a cable. The gripping device may further include a central rod coupled to the handle, wherein the cable can lie seated within a central rod. In some embodiments, a portion of the central rod is flexible, such that the central rod can be placed in a predetermined shape for reaching the crane hook from a plurality of angles. A pair of jaws may couple to the central rod, having a finger coupled to one of the pair of jaws. Particularly, the cable can be coupled to the finger, wherein when the cable is pulled by the trigger, the finger pivots downward toward the latch of the crane hook to open the same. As such, when the trigger is actuated, the cable is pulled, which pulls the finger down to open the latch of the crane hook. When the trigger is released, the cable is released and the finger retracts up. The gripping device can also include a pair of magnets coupled to each one of the pair of jaws for attracting each jaw to a side of the crane hook to hold the crane hook stable. Further, the gripping device may include a sensor for detecting the open and closed status of the hook. Moreover, the gripping device may include a transceiver to communicate the detected open and closed status of the hook to the crane cab user-interface for the driver to be notified.
In some embodiments, the central rod may include a first cylindrical portion and a second cylindrical portion, wherein the second cylindrical portion includes an interior flexible rod. A plurality of plates may be coupled to the interior rod to surround and shield the interior rod. Accordingly, the second cylindrical portion can be flexible, such that the central rod can be placed in a predetermined shape for reaching the crane hook from a plurality of angles.
In some embodiments, the gripping device may include a jaw-adjusting bracket coupled between the central rod and the pair of jaws to change the width of the grasping defined by the pair of jaws. In one embodiment, the jaw-adjusting bracket may include a first set of grooves, wherein a fork portion of a first one of the pair of jaws slidably couples to the jaw-adjusting bracket. The jaw-adjusting bracket may further include a second set of grooves, wherein a fork portion of a second one of the pair of jaws slidably couples to the jaw-adjusting bracket. As such, when the plurality of magnets coupled to the pair of jaws are attracted to the crane hook, the pair of jaws slidably move to form a smaller grasping width.
In another embodiment, the jaw-adjusting bracket may include a first fixed jaw of the pair of jaws and a second adjustable jaw, having a joint. The joint may include a worm thread. The jaw-adjusting bracket may further include a worm screw movably coupled to the worm thread. As such, when the worm screw is rotated about the worm thread, a second adjustable jaw moves a relative distance away from the first fixed jaw, to change the grasping width defined by the pair of jaws. In some embodiments, the jaw-adjusting bracket further includes a swivel member coupled to the central rod, wherein the jaw-adjusting bracket can swivel 360 degrees around an axis of the central rod.
In some embodiments, the transceiver may include a receiver coupled to receive the detected contact from the sensor. The transceiver may also include a transmitter coupled to the receiver to transmit the open and closed state of the latch of the crane hook to a second transceiver in the crane user-interface for notice to the driver of the crane.
Advantageously, of the three dangerous aspects of crane operation, the gripping device and innovative communication environment described herein addresses two of the three hazards. In particular, the gripping device disclosed herein protects and prevents workers from falling from heights that are necessary to climb to unlatch a crane hook from a forklift. Further, the communication system integrated within the novel design enables the driver of the cab to be alerted as to the open and closed state of the crane cab, such that construction workers are protected from collapsing loads. In particular, the gripping device for a crane hook and method of communicating open and closed status of the hook to a crane user-interface can save the construction worker the amount of time necessary to climb a flat bed truck which holds the load carried by the crane hook in an effort to connect and disconnect the crane hook and the load. Further, the novel gripping device for a crane hook can save the construction worker from various injuries including, flesh wounds, loss of limbs, broken bones, and/or death. As a result, the innovative design can save building construction companies substantial amounts of time and money that would have been used to cover injuries, damaged equipment, and property.

In operation, the user may grab the handle 110 of the gripping device 100 and extend the gripping device near the crane hook 142 to grasp the hook. In some embodiments, the user can place the central rod 112 in a predetermined shape for reaching the crane hook from a plurality of angles. In other embodiments, the user can swivel the jaw-adjusting bracket 120 to grab the hook from a variety of differing angles. Further, the user can direct the pair of jaws (130a, 130b) to couple and receive the crane hook 142. Specifically, when the pair of magnets (134a, 134b) coupled to each respective jaw (130a, 130b) comes in proximity to the crane hook 142, each respective jaw (130a, 130b) is attracted to each side of the crane hook, moving the jaws (130a, 130b) to stabilize the crane hook 142. Once the crane hook 142 is stabilized, the user can pull the trigger 102, which is attached to cable 108 that couples to finger 138. As a result, the cable 108 pulls the finger 138 downward to make contact with the latch 144 of the crane hook 142. Accordingly, the finger 138 opens the latch 144, enabling the user to move the crane hook away from the loop 152 of its connection to the forklift 150 holding the load 160 (as shown in

In some embodiments, the sensor 516 may couple to the finger 138 to detect contact between a finger of a gripping device and a latch of the crane hook. In particular, the sensor 516 may sense a first juxtapose position of magnets (134a, 134b) of a pair of jaws (130a, 130b) of the gripping device 100 with the crane hook 142. Further, in response to the sensing the first juxtapose position, the sensor 516 may sense a second juxtapose position of the finger 138 of the gripping device 100 with the latch 144 of the crane hook 142. Accordingly, the sensor 516 may affirm, in response to the sensed second juxtapose position, the contact between a finger 138 of a gripping device 100 and a latch 144 of the crane hook 142 exists. Consequently, the sensor 516 may also affirm the open state of the crane hook 142. In the alternative, the sensor 516 may also affirm the closed state of the crane hook 142 when either of the first and second juxtapose positions are absent. Accordingly, sensor 516 may transmit the open and closed state to the transceiver 520 of the client unit 510.
