Abstract

The invention relates to a lorry-mounted crane for rescue and a using method thereof, and aims to solve the problems that a lorry-mounted crane in the prior art is easy to vibrate and low in operation precision during operation. Comprising a driving vehicle, a movable arm, a first swing oil cylinder, a hoisting arm and a supporting device, a rotary supporting platform is arranged on a frame of the driving vehicle; the first end of the movable arm is hinged to the rotary supporting platform; the first end of the first swing oil cylinder is hinged to the rotary supporting platform, the second end of the first swing oil cylinder is hinged to the movable arm, the first end of the hoisting arm is hinged to the second end of the movable arm, a hoisting device is arranged on the hoisting arm and comprises a linear motion mechanism and a hoisting hoist, and the linear motion mechanism is connected with the hoisting hoist. The linear motion mechanism does reciprocating linear motion along the extension direction of the hoisting arm, and the hoisting hoist is arranged on the linear motion mechanism; and the supporting device is detachably connected with the second end of the hoisting arm.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a truck-mounted crane used for rescue and a method of using the same. Background technique [0002] The truck-mounted crane, also known as the truck-mounted crane, is a kind of material handling machinery, which can complete the vertical lifting and horizontal handling of heavy objects.
