Lorry-mounted crane and transport cart with same

Abstract

The invention discloses a lorry-mounted crane and a transport cart with the same. The lorry-mounted crane comprises a support assembly (1) and a rotary arm support assembly (2) mounted on the support assembly, wherein the arm support assembly can be overturned between a vertical position and a horizontal position. According to the lorry-mounted crane and the transport cart, when the transport cart with the lorry-mounted crane transports goods, the arm support assembly can be overturned to the horizontal position, so as to reduce the height of the lorry-mounted crane and improve the traffic capacity of the transport cart with the lorry-mounted crane; the transport cart with the lorry-mounted crane smoothly passes through places such as a bridge opening and a tunnel; and the transport work of the transport cart with the lorry-mounted crane is guaranteed. In addition, as the height of the lorry-mounted crane is lower after the arm support assembly is overturned to the horizontal position, the loading of some goods needing to stretch out from a chassis cannot be obstructed, thereby increasing a goods loading space. However, when the transport cart with the lorry-mounted crane carries out hoisting work, the arm support assembly can be overturned to the vertical position, so as to guarantee the normal implementation of the hoisting work.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a truck-mounted crane and a truck-mounted crane transporter including the truck-mounted crane. Background technique [0002] like figure 1 As shown, the truck-mounted crane generally includes a support assembly 1 and a rotatable jib assembly 2 mounted on the support assembly 1 through a slewing bearing 9, wherein the jib assembly 2 is in an upright state. The truck-mounted crane transport vehicle is formed by adding a truck-mounted crane on the basis of the truck chassis, which can realize the dual functions of lifting operation and cargo transportation. like figure 2 As shown, the truck-mounted transport vehicle generally includes a chassis 10 and a truck-mounted crane 11 , and the truck-mounted crane 11 is installed on the chassis 10 . Since the boom assembly 2 is in an upright state, the truck-mounted crane is relatively high as a whole. In this way, when the ...

AI Technical Summary

Problems solved by technology

Since the boom assembly 2 is in an upright state, the truck-mounted crane is relatively high as a whole. In this way, when the truck-mounted crane transport vehicle needs to pass through bridge openings, tunnels, etc., the upright boom assembly 2 may cause the truck-mounted crane to The heavy transport vehicle cannot pass through, which affects the transportation operation of the truck-mounted lifting transport vehicle
