Main Components

Let's explore the fundamental components of overhead crane systems and uncover their vital functions.

Bridge Frame

The bridge frame is the basic component of the overhead bridge crane, which is composed of bridge girder, end beam and other parts.

Bridge Girder: This is the primary load-bearing structure of the overhead bridge crane, responsible for supporting and carrying the weight of the entire overhead crane as well as the loads generated during lifting operations.
End Beam: Bears the load of the main girder and enables the bridge frame to move along the tracks through the wheels installed at its two ends, realizing the longitudinal operation of the overhead bridge crane.

Trolley and Driving Mechanism

The trolley is the main component of the overhead crane used for lifting materials. It is placed on the guide rail of the bridge frame and can move along the width of the workshop. The trolley is mainly composed of a trolley frame, a trolley driving mechanism and a lifting mechanism.

Trolley Frame: It is welded from steel plates, and is equipped with components such as the trolley driving mechanism, lifting mechanism, railings, and lifting limit switches.
Trolley Driving Mechanism: It is composed of motor, reducer, roller, brake, etc. The motor drives the driving wheel to move the trolley.
Lifting Mechanism: It is composed of motor, reducer, reel, brake, etc., and is used to drive the lifting movement of the hook. The lifting motor is connected to the reducer through the brake wheel and clutch. The output shaft of the reducer is connected to the lifting drum. The drum is wrapped with a wire rope, and the other end of the wire rope is connected to the hook.

Crane Running Mechanism

The crane running mechanism is the main component of the overhead bridge crane that moves along the length of the workshop, which is composed of driving motor, brake, transmission shaft, reducer and wheels.

Cabin

The cabin is the pod that operates the crane. The cabin is equipped with large and small crane running mechanism control devices, lifting mechanism control devices and crane protection devices, etc.

Electric System

Bridge crane is also equipped with electric system, including a trolley conductive device (auxiliary slide wire) and crane main power conductive devices a crane main power conductive device (main slide wire), which are used to provide power to the crane and trolley.

Feature of Overhead Crane

Three-Dimensional Motion Mechanism

The overhead crane is driven at longitudinal movement, while the trolley moves horizontally, and the hook lifts vertically.

High Adaptability to Working Conditions

The overhead crane can be specially configured to meet various working conditions, allowing it to perform normal lifting operations in specialized environments by utilizing adaptive components.

Bridge Load Structure

The overhead crane features a design typical of a bridge, consisting of a main beam and end beams. The main beam bears the load, providing a stable "skeleton" structure for the crane.

Wide Range of Lifting Capacity

The lifting capacity is designed to match actual scenarios, ranging from several tons to hundreds of tons, enabling it to handle diverse lifting tasks in various settings.

Versatile for Indoor and Outdoor Use

This overhead crane is suitable for indoor and outdoor locations, capable of lifting raw materials, finished products, and various goods, demonstrating strong adaptability to different working environments.

Comprehensive Buyer’s Guide for Overhead Crane

Identify your specific usage needs

Considering key factors such as weight capacity, lifting height, and span requirements.

Assess the working environment

For indoor spaces, evaluate the level of noise and the weight of heavy items. For outdoor settings, consider the type of track construction.

Choose the appropriate type of crane

A single girder overhead bridge crane is suitable for lifting goods weighing up to 15 tons, while a double girder overhead bridge crane can handle a wider variety of goods.

Select the crane based on usage frequency and task intensity

For high-frequency, heavy-load tasks, opt for a crane with higher capacity; if the frequency is low, a crane with lower capacity may suffice.
