Q355E Material Low Temperature Resistance Single Girder Mobile Gantry Crane 15 Tons With Wire Rope Hoist

Introduction:

A single girder gantry crane is a type of overhead crane that is typically used for material handling and lifting operations in outdoor environments or facilities where the installation of an overhead runway system is not feasible or practical. It consists of a single horizontal beam, known as the girder, which is supported by vertical legs on each end. The legs are mounted on wheels or rails, allowing the crane to move along the ground or on a track.

These cranes are operated by a control system that allows the operator to control the movements of the crane, including lifting, lowering, and horizontal travel. They can be equipped with various lifting mechanisms, such as wire rope hoists or chain hoists, depending on the specific application and load requirements.

Single girder gantry cranes are known for their compact design, which allows them to be easily assembled, disassembled, and relocated as needed. They offer a cost-effective solution for lifting and moving materials in areas where overhead crane systems may not be feasible.

Advantage

Versatility: They can be used in a wide range of industries and applications, such as construction sites, warehouses, manufacturing facilities, and shipping yards.

Cost-Effectiveness: Single girder gantry cranes are often more cost-effective compared to double girder gantry cranes, making them a popular choice for light to medium-duty lifting operations.

Easy Installation: Since they do not require an overhead runway system, single girder gantry cranes are relatively easy to install and can be quickly set up in outdoor or indoor environments.

Flexibility and Mobility: The wheels or rails on the legs allow the crane to be easily moved and repositioned as needed, providing flexibility in material handling operations.

Space Efficiency: Single girder gantry cranes require less headroom compared to other types of cranes, making them suitable for facilities with limited vertical space.

Gantry Crane
 

1.Capacity: The lifting capacity of a crane is typically measured in metric tons (t) or short tons (st). For example, a single girder gantry crane may have a lifting capacity of 5 tons or 10 tons.

2.Span: The span refers to the distance between the two vertical legs of the gantry crane. It is usually measured in meters (m) or feet (ft). For instance, a single girder gantry crane may have a span of 20 meters or 65 feet.

3.Height: The height of a single girder gantry crane can refer to the height of the legs or the height of lift. It is typically measured in meters (m) or feet (ft). For example, the height of the legs may be 6 meters or 20 feet, while the height of lift may be 8 meters or 26 feet.

4.Speed: The speed of the crane's movements, such as hoisting, trolley travel, and bridge travel, is typically measured in meters per minute (m/min) or feet per minute (ft/min).

5.Power: The power requirements of a single girder gantry crane, such as motor power or electrical supply, are usually measured in kilowatts (kW) or horsepower (hp).

Technical Parameter:

Gantry crane features:

1. Overloading is efficient;
2. Suitable for any environment (high temperature, explosion-proof, etc.);
3. Long lifespan: 30-50 years;
4. Easy installation and maintenance;
5. Reasonable structure and strong rigidity;
6. Speed variable frequency speed regulation;
7. The control method is cabin control or remote control;
8. According to the lifting cargo, the crane can be equipped with beam magnet or magnet chuck or grab bucket or C hook;
9. The crane is equipped with all standard safety devices such as mobile limit switches and loading limits to ensure the safe operation of the crane.

Component:

1. Girder: The single girder forms the main horizontal beam of the crane. It is usually made of steel and is designed to withstand the weight of the load and the forces applied during lifting operations.

2. Legs: The legs provide vertical support to the girder and are responsible for bearing the weight of the crane and the load. They are typically made of steel and are either fixed or equipped with wheels or rails for mobility.

3. End Carriages: The end carriages are located at each end of the girder and house the wheels or rails on which the crane moves. They enable the crane to travel along the length of the gantry and are often equipped with drive mechanisms for powered movement.

4. Hoist and Trolley: The hoist and trolley are responsible for lifting and moving the loads. The hoist is typically mounted on a trolley that travels along the length of the girder, allowing for horizontal movement of the load. The hoist can be operated manually or powered by electric or hydraulic systems, depending on the specific requirements of the application.

5. Controls: Single girder gantry cranes are operated using a control system that governs the movement of the crane, including lifting, lowering, and horizontal travel. The controls can be pendant-based, where the operator uses a handheld pendant controller, or remote-controlled, allowing for operation from a distance.
