Abstract
The utility model discloses an electric tire crane which comprises an underframe, wherein road wheels and supporting legs are mounted at the bottom of the underframe; a rotary table seat is mounted at the upper part of the underframe; a rotary table rotating around the rotary table seat is arranged on the rotary table seat; slewing mechanisms, a hoisting mechanism, a luffing mechanism and an upper rotary column are distributed on the rotary table; crane jibs are mounted on one side of the rotary table; luffing sheave blocks are mounted on the crane jibs through the upper rotary column; a balanced counterweight is arranged at the tail part of the rotary table; and the upper rotary column is a detachable A-bracket. The luffing mechanism, the hoisting mechanism and the slewing mechanisms of the electric tire crane are all distributed on the rotary table, and meanwhile, a detachable A-bracket type is adopted by the upper rotary column, so that not only does the crane have higher maneuverability when being driven, but also the dead weight of the crane is reduced.
Description
Technical field
The utility model relates to a kind of hoisting crane, relates in particular to a kind of electric tyre crane.
Background technology
The principal feature of wheel-mounted crane is: its travel operator's compartment and the lifting control cabin unites two into one, be to be developed by crawler crane (crawler crane) to form, crawler belt and the mobile roof support of traveling gear are partly become the chassis that tire is arranged, overcome the shortcoming that crawler crane (crawler crane) caterpillar block road pavement damages, the speed of travelling is also fast than crawler crane (crawler crane); Operation is stable, hoisting capacity large, can lift heavy walking in particular range.
Plurality of advantages in view of wheel-mounted crane, it has been widely used in the lift heavy operation in the limited place of the miles of relative movement such as goods yard, harbour, building site, traditional wheel-mounted crane is unreasonable because of rotary column on it and turntable layout, has the shortcoming that volume is large, manoevreability is poor.
The utility model content
The purpose of this utility model is to provide a kind of electric tyre crane, and it is by the improvement to upper rotary column and operating mechanism, and reduce in the space that operating mechanism is taken, and manoevreability is good, to solve the problem that electric tyre crane exists in the prior art.
For reaching this purpose, the utility model by the following technical solutions:
