Description

technical field [0001] The invention relates to the technical field of a truck-mounted crane control room, in particular to a truck-mounted crane control room with an adjustable backrest angle. Background technique [0002] Crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places. The name of crane is the unified title of lifting machinery. It is usually called crane, mainly car crane, crawler crane and tire crane. The usefulness of crane For hoisting equipment, emergency rescue, lifting, machinery, and rescue, the control room of the truck-mounted crane is used to control the up and down, left and right, front and rear, etc. of the lifted objects. There are mechanical joysticks, electrical control electrical cabinets, and pneumatic or hydraulic devices. [0003] The existing truck-mounted crane control room cannot adjust the angle of the seat back. The driver sits for a long time at an angle that...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a vehicle-mounted crane control room with an adjustable backrest angle, to solve the problem that the existing vehicle-mounted crane control room cannot adjust the angle of the seat back in the background technology, and the driver can not adjust the angle of the seat back for a long time. Sitting at a suitable angle for a long time will easily cause physical damage and affect work efficiency. At the same time, the seat position cannot be adjusted, which will also affect its work efficiency and cannot meet people's needs.
