Top Running Box Frame Double Girder Gantry Crane With Trolley

Product Description

Double girder gantry crane is a type of overhead crane that utilizes two parallel girders to support the crane's trolley and hoist system. These cranes are commonly used in various industries for heavy-duty lifting and handling applications. They can handle loads ranging from a few tons to hundreds of tons, making them a versatile and powerful solution for handling heavy materials.

Product Parameters

Main Components

A double girder gantry crane typically consists of the following components:

1. Girders: Two parallel girders, running the length of the crane, support the trolley and hoist system. They are usually made of steel and provide the structural strength needed to handle the crane's rated capacity.

2. Legs: Four or more legs, depending on the crane's design, provide vertical support for the girders. Gantry cranes can either have fixed or adjustable legs, which are used to adjust the height of the crane.

3. End trucks: These are located at both ends of the girders and enable the crane to move along the rails. They consist of multiple wheels that bear the crane's weight and allow for smooth movement.

4. Rails: Rails are placed on the ground or on a raised structure and provide a path for the movement of the end trucks. The rails are securely anchored to ensure stability and safety during crane operation.

5. Trolley: The trolley is a wheeled unit that travels along the girders, carrying the hoist system. It can move horizontally, allowing for precise positioning of the load.

6. Hoist: The hoist is the main lifting mechanism of the crane, and it is suspended from the trolley. It typically consists of a motor, gearbox, drum, wire rope or chain, and hook. The hoist system is responsible for raising, lowering, and holding the load.

Advantages

Some advantages of using a double girder gantry crane include:

• High load capacity: Double girder cranes can handle heavy loads, making them ideal for various industrial applications.

• Increased span: The double girder design allows for a wider span compared to single girder cranes, providing more coverage area for lifting operations.

• Better height and headroom: Double girder cranes offer better hook height and headroom, which can be beneficial when lifting tall or bulky loads.

• Increased stability: Due to the double girder design, these cranes offer greater stability and rigidity, which can help improve safety and reduce wear on components.
