摘要： Hoists, platforms and davits are described as well as methods of securing same to telecommunication and other towers. The hoists, platforms and davits may be secured to the towers on a temporary basis using clamps. The clamps may include brackets and cables. The cables may be attached to the brackets, may wrap around the outer surface/perimeter of the tower pole/leg and may use tension to keep the bracket in place.

摘要： A method for searching transition routes from an initial state of a plurality of stackable items to a target state by a computer at predetermined conditions includes connecting between transitionable states at an edge by a single handling operation transitioning from the initial state to the target state, to generate a state space graph; evaluating a lower bound of handling operation cost from a certain state to the target state, based on both the stacking sequence of the plurality of items in the certain state and the stacking sequence of the plurality of items in the target state; and searching a route from the initial state to the target state where the handling operation cost is minimal on the state space graph using a heuristic search algorithm based on the lower bound.

摘要： Bales of crop scattered on a field are loaded on a vehicle by means of a loading apparatus mounted thereon. The loading apparatus comprises a gripping device for successively gripping the bales on the ground and lifting them to a position on the platform of the vehicle. The movements of the gripping device between said positions are performed automatically and controlled by a programmable controlling device which may be programmed in accordance with the desired pattern of stacking the bales on the vehicle platform. While the gripping device is lifting a bale and placing it on the vehicle platform and returning to the bale engaging position the driver drives the vehicle to the next bale to be loaded. The loading apparatus may also be used for reloading the vehicle if the control device is provided with a suitable program.

摘要： This crane control device controls the operation of a boom and a winch and transports a load from a start point to an end point, the control device comprising: an acquisition unit that acquires position information of the start point and position information of the end point; a horizontal trajectory generation unit that, by using an optimal control theory, generates a horizontal trajectory for a distal-end part of the boom as represented by a horizontal-direction component of a straight line linking the start point and the end point; a movement trajectory generation unit that generates a trajectory of movement of the boom for transporting the load so as to follow the horizontal trajectory, and a trajectory of rotational movement of the winch; and a movement control unit that controls the boom and the winch based on the trajectory of movement of the boom and the winch.
