Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the single rubber wheel of the current engineering vehicle cannot cope with various complex road surfaces in use, and to provide an engineering vehicle with a spare lifting track wheel, which can be used in an emergency by touching the ground with the lifting track wheel
[0005] The present invention has the following advantages and effects: the engineering vehicle thus constituted can easily move the track wheels by touching the ground when the road surface cannot be moved due to an accident during use, which solves the problem of accidents caused by the single rubber wheel of the engineering vehicle. The problem of being unable to move, the design is scientific, and the engineering vehicle is more convenient to use

Abstract

The invention provides an engineering truck provided with lifting crawler wheels for use. Crawler wheels connected through hydraulic lifting rods are arranged in the space between front and back rubber wheels under a truck body of the engineering truck. Therefore, when the rubber wheels cannot be used due to loose and soft roadbeds in the running process of the engineering truck, the crawler wheels can descend to touch the ground for use.

Description

technical field [0001] The invention relates to an engineering vehicle, in particular to an engineering vehicle provided with a spare lifting track wheel. Background technique [0002] Now engineering vehicles have been popularized in engineering use, especially self-unloading engineering vehicles are more convenient to use in many projects, but during the use of engineering vehicles, because the wheels are rubber wheels, when walking on soft ground and muddy roads, the wheels touch the ground. limited, resulting in the inability to move, which brings a lot of trouble to the normal operation of the project. Under normal circumstances, it is necessary to increase the throttle to increase power, but it still cannot solve the fundamental problem. At the same time, increasing the throttle not only causes energy consumption but also causes smoke Excessive air pollution. Contents of the invention [0003] The purpose of the present invention is to solve the problem that a singl...
