Problems solved by technology

[0002] The truck-mounted crane is a kind of equipment that realizes the lifting and lowering of goods by hydraulically driving the lifting and telescopic boom. It has the functions of slewing, lifting, telescopic and hoisting. There are two types of truck-mounted cranes, which are mainly composed of three parts: mechanical structure, hydraulic system and electrical system. For cranes, the support frame of the slewing mechanism is high, the lifting moment is small, and the stability is poor

Abstract

The invention discloses a lorry-mounted crane, and belongs to the field of lorry-mounted cranes. A base is designed by adopting a low and flat structure; a positioning mechanism of an amplitude variation movable arm is arranged right below the amplitude variation movable arm; a telescopic oil cylinder is arranged in a telescopic arm, so that the height of the whole crane is lowered effectively, and the stability of the whole crane is improved; a height warning label and an angle indicator are arranged at two sides of the amplitude variation movable arm, and provide reference and help for operators. The adopted technical scheme is that the lorry-mounted crane comprises the base, the amplitude variation movable arm and a lifting arm; the rear end of the amplitude variation movable arm is hinged with the base; the front end of the amplitude variation movable arm is connected with the lifting arm; the base comprises a slewing mechanism and a support frame; the upper end of the support frame is hinged with the amplitude variation movable arm; the lower end of the support frame is connected with the slewing mechanism. The technical scheme can be widely applied to the field of lorry-mounted cranes.

Description

technical field [0001] The truck-mounted crane of the invention belongs to the technical field of truck-mounted cranes. Background technique [0002] The truck-mounted crane is a kind of equipment that realizes the lifting and lowering of goods by hydraulically driving the lifting and telescopic boom. It has the functions of slewing, lifting, telescopic and hoisting. There are two types of truck-mounted cranes, which are mainly composed of three parts: mechanical structure, hydraulic system and electrical system. For cranes, the support frame of the slewing mechanism is relatively high, the lifting moment is small, and the stability is poor. Contents of the invention [0003] The present invention overcomes the deficiencies in the prior art, and provides a truck-mounted crane, including a base and a luffing boom, the luffing boom is hinged to the base, the base includes a slewing mechanism and a support frame, the The upper end of the support frame is hinged with the luf...
