Abstract:
1. A vehicle comprising: a vehicle body on which a load is loaded; a loading/unloading apparatus installed in the vehicle body and loading and unloading the load on and from the vehicle body; and a controller for controlling the operation of the loading/unloading apparatus based on a manipulation instruction from a manipulation remote control unit, wherein the loading/unloading apparatus includes: rotary shafts installed in the vehicle body such that axial directions thereof coincide with a forward and rearward direction of the vehicle body; a pair of booms supported by the vehicle body via the rotary shaft to be rotatable toward a left and right direction of the vehicle body and installed at front and rear sides of the vehicle body at a predetermined interval; and a working beam installed between the pair of booms and suspending and maintaining the load such that as the pair of booms are rotated in the left and right direction of the vehicle body, the load is loaded/unloaded, and wherein the controller includes: a load factor acquiring section acquiring a load factor of the loading/unloading apparatus; a first reference value determining section determining whether the load factor of the loading/unloading apparatus acquired by the load factor acquiring section reaches a first reference value; a stopping section stopping the operation of the loading/unloading apparatus when the first reference value determining section determines that the load factor of the loading/unloading apparatus has reached the first reference value; a second reference value determining section determining whether the load factor of the loading/unloading apparatus acquired by the load factor acquiring section has reached a second reference value that is smaller in load factor than the first reference value; and an operation speed reducing section reducing operation speed of the loading/unloading apparatus when the second reference value determining section determines that the load factor of the loading/unloading apparatus has reached the second reference value.
