15 Years Double Girder Overhead Cranes Manufactruer

Introduction

Double girder overhead crane is composed of main beam, cross traveling mechanism, long traveling mechanism, and electrical equipment. According to the frequency of use, it is divided into three working levels: A5, A6, A7, A8. It is widely used in steel factory, construction industrial, warehouse, freight yard, cement factory and other heavy duty works.

It is rely on the bridge frame along the workshop orbital direction moving longitudinal, the trolley along the main beam direction moving transverse and the hook lifting movement to work. As it max lifting weight up to 350, so it realized most of client needs.

We design and manufacture custom-built cranes according to customer specifications. When you order the cranes from us, please give us the detail of your requirements and your using situation, we will be the one to ensure what we offer is totally according to your requirement. And our components are designed with the idea of adjustment free and according to the lift time of the crane, so you can always rely on the functioning of the cranes.
