Abstract

The invention provides a small-sized autocrane which comprises an operating valve, a bracket, a loading limit rod, a lower knuckle arm, a foldable hydraulic cylinder, an upper knuckle arm, a telescopic hydraulic cylinder, a telescopic arm, a lifting hook, a middle arm, a lifting hydraulic cylinder, a swing mechanism, a rack and a supporting leg, wherein the bracket is arranged at the top of the operating valve; one end of the bracket is in close contact with the lifting hydraulic cylinder; the loading limit rod is arranged on one side of the lifting hydraulic cylinder, and is arranged at one end of the lower knuckle arm; the foldable hydraulic cylinder is arranged on one side of the lower knuckle arm; the foldable hydraulic cylinder is in close connection with the upper knuckle arm; the telescopic hydraulic cylinder is arranged on one side of the upper knuckle arm; the telescopic arm is fixedly connected with the tail end of the telescopic hydraulic cylinder; the lifting hook is arranged at one end of the telescopic arm. Pressure on the road surface by a vehicle below the autocrane is reduced, and a lifting arm does not need to be unloaded from the vehicle to be independently transported; compared with the conventional large-size autocrane, the labor is saved, the transportation cost is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a crane, in particular to a small truck crane, which belongs to the field of mechanical lifting. Background technique [0002] A car crane is a kind of crane installed on an ordinary car chassis or a special car chassis, and its driving cab is set separately from the lifting control room. The chassis performance of the truck crane is equivalent to that of a truck with the same total weight, which meets the technical requirements of road vehicles, so it can pass unimpeded on various roads. This kind of crane is generally equipped with two control rooms for getting on and off the car, and the outriggers must be extended to keep it stable during operation. With the rapid development of my country's economic construction, construction sites have higher and higher requirements for the lifting capacity of cranes. Various companies have successively launched large-tonnage truck cranes to meet market requirements. [0003] However, l...
