Claims

[Scope of utility model registration request]

In a crane truck equipped with a lifting hook at the tip of a straight-extending boom, there is a boom length detector that detects the length of the boom, a boom undulation angle detector that detects the undulation angle of the boom, and a winch rope payout length. a rope length detector for detecting the rope length, a mode changeover switch for switching between two modes: parallel movement of the hook and horizontal movement of the suspended load, and a controller that receives signals from each of the detectors and the mode changeover switch and controls the winch. 1. A crane truck hook control device comprising: a computing unit that sends out a predetermined control signal; and a winch operation valve that is controlled by the output signal of the controller.
