Mast Crane

Product Introduction

The Mast Crane is a non-standard, fixed-type derrick crane designed for heavy-duty lifting operations. It uses an upright mast as its primary load-bearing structure and is typically equipped with a boom, hoisting winch, guy ropes, base supports, and other essential components. By operating wire ropes and the associated lifting mechanisms, the crane can perform heavy-load hoisting and, depending on its configuration, boom luffing and slewing operations.

Mast cranes are particularly suitable for heavy component installation, large equipment handling, and construction projects in confined or space-restricted working environments.

The WGQ500T Mast Crane is a large-capacity fixed lifting solution custom-developed by Chunhua for a leading global transformer manufacturer, with whom the company has maintained a long-term, in-depth cooperation. The equipment received the honor of being recognized as Anhui Province’s first-of-its-kind fixed dock lifting equipment. With its substantial lifting capacity and stable operation, it is primarily designed for lifting and transferring large transformers and other heavy industrial equipment.

Key Features

• Heavy-Duty Lifting Capacity: Designed for demanding heavy-load lifting operations, including the handling of oversized industrial components and large transformers.
• Adaptability to Confined Spaces: Its fixed structural configuration can be tailored to challenging sites with limited working space and specific installation requirements.
• Customized Engineering: Non-standard design allows the crane configuration to be adapted to project-specific lifting conditions, equipment dimensions, and operational requirements.
• Flexible Lifting Operations: Depending on the engineered configuration, the crane can support lifting, boom adjustment, and slewing operations to accommodate different lifting procedures.
• Reliable Operation and Maintainability: A purpose-designed mechanical configuration supports stable operation and facilitates routine inspection and maintenance.
• Controlled Stability and Safety: Structural stability and overturning resistance must be evaluated against the intended load, working configuration, foundation conditions, and applicable engineering requirements.

Working Principle

The Mast Crane uses an upright mast as its primary load-bearing structure, supported by a base and an engineered stabilization system. A boom and hoisting winch work together with wire ropes to lift and position heavy loads.

During operation, the hoisting mechanism winds or releases the wire rope to raise or lower the load. Where the design includes a luffing mechanism, the boom angle can be adjusted to change the working radius. Where a slewing mechanism is provided, the crane can rotate the lifting assembly to position the load within its permitted operating range.

The crane’s stability depends on the structural design, guy-rope arrangement where applicable, foundation or anchorage conditions, load distribution, and operating configuration. These factors must be verified through project-specific engineering calculations and operating procedures before the equipment is put into service.

Applications

Mast cranes are suitable for heavy lifting and installation projects where conventional lifting equipment may be difficult to deploy or where specialized lifting procedures are required.

Typical applications include:

• Transformer Installation and Handling: Lifting and transferring large power transformers and associated heavy equipment.
• Dockside Heavy Lifting: Handling oversized components in fixed dockside lifting applications, subject to the approved crane configuration.
• Industrial Equipment Installation: Positioning heavy machinery, large assemblies, and other industrial components.
• Construction Projects: Supporting heavy structural component installation at sites with restricted space or complex lifting requirements.
• Customized Engineering Projects: Providing project-specific lifting solutions for non-standard loads, installation conditions, and specialized lifting procedures.

OEM & Customization

Chunhua provides customized mast crane solutions for specialized heavy-lifting applications. Design considerations can include rated lifting capacity, lifting height, working radius, boom configuration, hoisting and slewing mechanisms, support and anchorage arrangements, and site-specific operating conditions.

For projects involving large transformers, dockside lifting, or other oversized equipment, the proposed configuration should be developed according to the load characteristics, lifting procedure, site layout, foundation conditions, and applicable technical requirements.

Customers are encouraged to provide the load weight, load dimensions, required lifting height, working radius, site drawings, and intended lifting procedure so that the appropriate technical configuration can be evaluated.

FAQ

1. What is a mast crane used for?

A mast crane is used for specialized heavy lifting, equipment installation, and handling operations. It is particularly useful for projects involving oversized components, restricted working spaces, or non-standard lifting requirements.

2. What is the lifting capacity of the WGQ500T Mast Crane?

The WGQ500T Mast Crane is a customized heavy-duty lifting solution with a stated lifting capacity of 500 tonnes. Its permissible load depends on the approved technical configuration and specified operating conditions.

3. Can a mast crane be customized for transformer installation?

Yes. Mast cranes can be engineered for transformer installation and other specialized lifting applications. The design must account for the load weight and dimensions, lifting height, working radius, site conditions, and required lifting procedure.

4. What information is needed to select a suitable mast crane?

Important information includes the maximum load weight, lifting height, working radius, load dimensions, site layout, foundation or anchorage conditions, and the required lifting and positioning sequence.

5. What should be considered when evaluating mast crane safety?

Key considerations include structural strength, stability and overturning resistance, foundation and anchorage design, wire-rope and hoisting-system capacity, operating limits, inspection requirements, and project-specific safety procedures.
