Outdoors Use Box Type Double Girder Gantry Crane With Electric Trolley

Product Description

A double girder gantry crane is a type of crane that features two parallel girders as the main load-bearing components. It is commonly used in industrial environments, construction sites, shipping yards, and other locations where heavy loads need to be lifted and moved.

Product Parameters

Features:

1. Double Girder Design: The crane consists of two horizontal girders that run parallel to each other and are connected by cross beams. The double girder design provides increased stability, higher lifting capacity, and better control compared to single girder gantry cranes.

2. Load Capacity: Double girder gantry cranes are capable of lifting and moving heavy loads, ranging from a few tons to several hundred tons or more. The load capacity is determined by various factors, including the strength and design of the girders, the hoisting mechanism, and the configuration of the crane.

3. Gantry Structure: The gantry structure supports the girders and provides stability to the crane. It typically consists of legs or columns at each end, along with bracing and cross beams. The gantry structure can be designed as a fixed or adjustable height configuration, depending on the specific application requirements.

4. Hoisting Mechanism: The hoisting mechanism is responsible for lifting and lowering loads. It typically includes an electric hoist or a trolley system that travels along the girders. The hoisting mechanism is powered by an electric motor and can be controlled using a control pendant or a remote control.

5. Travel Movement: Double girder gantry cranes can have various travel movements, depending on the specific design and requirements. They can be equipped with wheels or tracks to facilitate movement on paved or uneven surfaces. Some cranes may also have additional mechanisms for lateral movement.

6. Control System: Double girder gantry cranes are operated using a control pendant or a remote control unit. The operator can control the movement of the hoisting mechanism, including lifting, lowering, and horizontal travel. Some advanced cranes may also feature programmable controls and automation functions.

7. Safety Features: Double girder gantry cranes incorporate various safety features to ensure safe operation. These may include overload protection systems, emergency stop buttons, limit switches to prevent overtravel, and safety interlocks to protect personnel and equipment.
