A wireless assembly for use with a long line, an aircraft and a battery is provided, the wireless assembly comprising: a hook, which includes an electro-mechanical actuator; a waterproof housing mounted on the hook; a wireless receiver which includes a microprocessor, is retained in the waterproof housing and is in electrical communication with the electro-mechanical actuator; a wireless transmitter, which includes a microprocessor; and a switch which is in electrical communication with the wireless transmitter, the wireless transmitter and the switch for locating in the aircraft. A method of wirelessly controlling the release of a load from the hook is also provided.

A mobility handling vehicle mechanism includes a tubular frame having a battery and winch secured within the frame. A telescoping lift arm is movably secured to the outside top surface of the frame. A hook and cable are secured to the end of the telescoping lift arm and winch. When secured within a transporting vehicle, the device enables a user to utilize the winch to lift a mobility handling vehicle into the transporting vehicle.

Modular crane attachment device for purlins is a crane attachment jig that attaches to the hook of a crane and functions to lift a plurality of purlins in one lift to place each purlin at the precise location on the rafters of a building under construction to allow for immediate attachment of all purlins to the rafters wherein each purlin is fastened into place while held by the crane and modular crane attachment device for purlins, which functions as a giant assembly jig in this manner. Modular crane attachment device for purlins is modular so that it can be broken down by hand into a bundle of 10-20 foot long structural members, fittings, and cables. Modular crane attachment device for purlins is modular so it can be assembled in any length and width to fit any application of any number and any length of purlins required for the building.

A swivel hook assembly which comprises a hook unit that supports a hook which facilitates suspending a desire piece of equipment from the swivel hook assembly. The hook unit is engageable with a free end of a wire cable that controls vertical and horizontal movement of the hook unit. A hook coupling has an upper end which engages with a jib and a second end for engaging with the hook unit. When the hook unit is spaced away and disengaged from the hook coupling, the hook unit is rotatable relative to the hook coupling. However, when the hook unit is moved, by the wire cable, into engagement with the hook coupling, relative rotation between the hook unit and the hook coupling is prevented and more precise control over the suspended desire piece of equipment is achieved by the operator.

A crane block mountable safety beacon device for increasing awareness of a crane block includes a housing that is mountable to a crane block. A set of bulbs that is coupled to the housing selectively emits light to indicate a position of the crane block to an operator of a crane utilizing the crane block and to persons proximate to the crane block.

The invention relates to a device (1) for the emergency manual control of a remote system, said device comprising: a body (2); a manual actuator (3); a system for transmitting a movement of the manual actuator (3) to the remote system; and a security element that limits the possibilities for an operator to actuate said manual actuator. Said manual actuator (3) comprises a keeper (300) and the security element is a latch (4) that can be rotated about a latch axis (A2) of the body and comprises a notch (40) that can cooperate with the keeper (300).
