Problems solved by technology

The operator of the lower operation mode operates the truck-mounted crane on the ground. Due to factors such as height, height of the cargo box railing, and height of the chassis, the operator has insufficient vision and is inconvenient to lift the cargo.
The operator in the high-position operation mode must be on the top of the slewing column of the truck-mounted crane to have a wide field of vision. Because the workbench is too high, it is not convenient for the operator to go up and down, especially in bad weather, and the safety is relatively poor.
Most of the existing neutral operation methods have complex structures, high manufacturing costs, and limited installation angles of multi-way valves
Some truck-mounted cranes cannot perform bilateral operation at the lower position while realizing the middle position operation, and it is not easy to repair the crane if it fails

Abstract

The invention relates to a neutral position operating device for a straight-arm type truck-mounted crane and belongs to the technical field of auxiliary equipment of the straight-arm type truck-mounted crane. The neutral position operating device is simple in structure, convenient to operate and convenient to dismount and maintain. The neutral position operating device comprises a multi-way valve, a supporting platform and an operating rod assembly, wherein the supporting platform is mounted on a base cross beam of the crane, positioned between a cab and a packing box and positioned on one side of a stand column of the crane; the operating rod assembly is arranged at the top of the supporting platform, and the multi-way valve is arranged under the supporting platform; the operating rod assembly comprises a multi-way valve controller, a remote accelerator cable, an operation box, a support and an operating handle. The neutral position operating device is applied to the straight-arm type truck-mounted crane.

Description

technical field [0001] The utility model relates to a median operating device of a straight-arm type truck-mounted crane, which belongs to the technical field of straight-arm type truck-mounted crane auxiliary equipment. Background technique [0002] The operating device of the straight arm truck-mounted crane mainly has three modes: lower position operation, high position operation and middle position operation. There are some deficiencies in these three existing modes of operation. The operator of the lower operation mode operates the truck-mounted crane on the ground. Due to the influence of factors such as height, height of the cargo box railing, and height of the chassis, the operator has insufficient vision and is inconvenient to lift the cargo. The operator in the high-position operation mode must be on the slewing column of the truck-mounted crane to have a wide field of vision. Because the workbench is too high, it is not convenient for the operator to go up and do...
