<p>The present invention provides a crane with off-road tyres and a method, apparatus and system for controlling the engine thereof, used for solving the problem in the prior art that the safety performance of cranes with off-road tyres is lacking when moving with a suspended weight. The method comprises: confirming the operating status of a crane with off-road tyres, the operating status comprising a moving status and a suspended weight status; determining the idle speed of the engine thereof according to the operating status, wherein, if the operating status is moving status, determining the idle speed as a first idle speed and, if the operating status is suspended weight status, determining the idle speed as a second idle speed, the second idle speed being greater than the first idle speed; and receiving a voltage signal from a throttle pedal, determining the rotational speed of the engine according to the voltage signal and the idle speed, and then controlling the engine according to the rotational speed. Use of the technical solution of the present invention helps to avoid the risk of failure caused by moving with a suspended weight, and improves the safety performance of cranes with off-road tyres when moving with a suspended weight.</p> |
