Truss type gantry crane

Types of truss type gantry cranes

A truss type gantry crane is a type of crane consisting of two vertical trusses and a horizontal truss connecting them. It comes in various types, each with different features and applications. Here are some of them:

• Single Girder Truss Gantry Crane

This type of gantry crane consists of a single horizontal girder supported by two vertical trusses. The girder is the main beam that runs horizontally across the crane's span. Single girder truss gantry cranes are commonly used in outdoor applications for lifting loads of up to 15 tons. They are ideal for situations where overhead clearance is limited.

• Double Girder truss gantry crane

Similar to the single girder truss gantry crane, the double girder truss gantry crane has two horizontal girders supported by vertical trusses. The double girder design provides increased lifting capacity and stability, making it suitable for handling heavier loads. Double girder truss gantry cranes are commonly used in industrial yards, logistics centers, and construction sites.

• Box Truss Gantry Crane

Box truss gantry cranes have a rectangular box-shaped truss structure. The box truss design provides excellent strength-to-weight ratio, making the crane lightweight and strong. Box truss gantry cranes are commonly used in workshops, assembly lines, and warehouses. They are suitable for applications that require frequent movement and versatility.

• Portable Truss Gantry Crane

Portable truss gantry cranes are designed to be easily movable and disassembled. They are commonly used in temporary construction sites, events, and maintenance projects. Portable truss gantry cranes are lightweight and compact, allowing for quick setup and transportation. They are ideal for situations where a temporary lifting solution is needed.

Specification & maintenance of truss type gantry cranes

Some important specifications of truss type gantry cranes include:

• Span: The span of the crane is the horizontal distance between the two supporting legs. The span determines the coverage area of the crane, which is the width of the working area. The span should be equal to or less than the width of the working area. A span that is too large can lead to a decrease in the load-carrying capacity and stability of the crane.
Truss height: The height of the truss is the vertical distance from the ground to the main girder. The height of the truss determines the lifting height of the crane, i.e., the maximum height to which the crane can lift the load. The height of the truss should be chosen based on the height of the load to be lifted and the working space available.
• Lifting capacity: The maximum weight that the crane can lift is the lifting capacity. It should be chosen according to the weight of the load to be lifted. The lifting capacity of the crane is often expressed in tons. For example, a 3-ton crane can lift a maximum weight of 3 tons. The lifting capacity of the crane should be greater than or equal to the weight of the heaviest load to be lifted. The crane is most stable when the load is at the center of the span.
• Motor power: The power of the motor of the crane is expressed in kilowatts or horsepower. The lifting, lowering, and traveling functions of the crane are performed by the motor. The power of the motor should be chosen according to the weight of the heaviest load to be lifted and the working conditions of the crane. The power of the motor should be sufficient for the crane to work well under the given conditions.

Proper maintenance of a truss type gantry crane is essential for its safe and efficient operation. Regular maintenance helps to identify and address potential issues before they become major problems, reducing the risk of accidents and downtime. Maintenance tasks typically include:

• Inspecting the crane for signs of wear, damage, or misalignment of components.
• Lubricating moving parts to reduce friction and wear.
• Checking wire ropes and hoist chains for wear, distortion, or lubrication needs. This helps to identify and remove any stretched, broken strands or any other defects that may affect the proper functioning of the ropes and chains.
• Inspecting electrical systems and controls to ensure proper functioning and correct any issues.
• Examining the crane's hooks, lifting devices, and safety devices to ensure they are functioning correctly.
• Inspecting the crane wheels and rails for abnormal wear or damage.
