Introduction

The single girder overhead crane is designed according to GB3811-2008 and JB/T1306-2008 standards, and it is equipped with electric hoists. It is widely used in mechanical processing, assembly, repair, warehouses, and other workplaces. It is an important tool and equipment for modern industrial enterprises to realize the mechanization and automation of the production process, reduce heavy manual labor, and improve labor productivity.

Single girder eot cranes consist single bridge beam, two rails, end trucks, two runway beams and a hoist to lift the load that runs on the bridge beam. The end trucks run on the rails which are fixed on the runway beams. It is one of the most cost effective equipment for the medium and heavy loads. Single girder eot cranes offer the greatest flexibility for the cover area and the movement control. As is installing on the upper part of the factory, a single girder eot crane occupies the least floor space and meets the fewest number of obstacles in the range of the movement. After so many years’ endeavor, our company has successfully get into the top-ranking single girder eot cranes manufacturer. Single girder eot crane can be modified to adapt the changing demands. The operation of this kind equipment is quite flexible. It also rather easy be tailored depend on the unique conditions of your plant and the variety of the productions and loads.

Structural Component

A Single Girder Overhead Crane is mainly composed of the main beam, end carriages, hoist trolley, long travel (gantry) mechanism, and electrical control system. Here is a detailed structural breakdown:

Main Beam: This is the primary load-bearing component. It is usually a box-section or I-beam structure made of steel. Spanning horizontally above the workshop or rails, it supports the weight of the hoist trolley and the lifted load.
End Carriages: Connected to both ends of the main beam, these support the beam and are equipped with wheels, allowing the crane to travel longitudinally along the runway rails.
Hoist Trolley: Suspended beneath the main beam, this unit travels horizontally along a track mounted on the main beam. It consists of a trolley frame, a hoisting mechanism, and a trolley travel mechanism, and is used for lifting and moving heavy loads.
: Installed on the end carriages, this system includes the motor, reducer, brakes, and wheels. It drives the crane to move longitudinally along the rails.
Electrical Control System: This includes the control cabinet, operation pendant (control buttons), limit switches, and cables. It is used to control the crane’s various movements and ensure safe operation.
