Abstract

At present, most front lifting-up dump trucks adopt a multi-stage sleeve-type plunger cylinder single-cylinder direct push structure. Although this type of structure has certain advantages, due to the poor working conditions of dump trucks, the lateral stability of its cargo box is poor, resulting in a large off-load torque. This often causes the lifting cylinder to become stuck or twisted, and even causes rollover and other accidents. At present, some manufacturers have improved the structure, but new problems have appeared. In order to better solve the problem of lateral stability of the cargo box, this article is based on the problems of the multi-stage sleeve-type plunger cylinder single-cylinder direct push structure of the front lifting-up dump truck, combined with the rear-mounted double cylinder lifting mechanism, and analyzed a two-cylinder synchronous lifting system for front lifting-up dump truck. This system can better solve the problem of lateral stability.
