High Quality Overhead Crane Single Girder Double Girder Overhead Crane

Product Description

It be used for transporting materials in a line, which can directly connect the loading worker and unloading worker, such as
the out-back haul, circle haul, etc. single track is of flexible travelling directions, running arbitrarily from the single track line
to multiple tracks, and ring track. So it is widely used in all walks of life conveying link or system.
 

Advantage:

1.Decrease industrial costing;

2.Design the whole structure based on original industry space and requirements;

3.Increase or decrease devices based on production demands, easy disassembly and relocation,

not affect other equipments working;

4.Light and small structure, easy operation and accurate positioning;

5.Low consumption & energy and environmental protection;

6.Low noise: simple structure, low Failure rate;

7.High Comprehensive benefits.

The have two types

A. Single girder overhead crane

Single beam overhead crane configuration is made up of a single bridge girder, two end carriages and a hoist with trolley,
which runs along the bottom flange of the bridge girder between the end carriages.
* It is widely used in industrial factory, warehouse, workshop, stock ground, workstation factory, goods yard etc.
* It looks like bridge, because both ends of girder are on the tall concrete column and metal support structure.
* It consists of metal structure, crane travelling mechanism, lifting mechanism, safety protection and operation.

B.Double girder overhead crane
Double beam overhead crane configuration is made up of two bridge girders, two end carriages and a hoist with trolley.
The hoist travels on top of rails that are mounted to the top of bridge girders. It is widely used for transferring material,
goods equipment installation and maintenance in factory, power station, storeroom, warehouse etc.

Product Struture

Main Girder:

1. Main girder uses bias-rail box type structure, with optimized design and light dead weight. 
2. Steel material. Q235B / Q345B.
3. The cover and web plate should get surface rust removal by roller-way conveyor blasting machine before welding;this 
     blasting machine can perform blanking, sandblasting, painting and drying.
4. The welding work of main girder should be performed on work platform (welding assembly unit). In order to avoid 
    distortion of main beam, we adopts U-shaped welding assembly unit to assure that vertical deflection degree between 
    the top cover plate and joint edge of stiffened plate and web plate is no more than H/200, and also effectively reduce the 
    partial wave of web plate.
