Adjustable mobile gantry crane is a popular choice for temporary lifting, workstation transport, or flexible use in multiple scenarios, thanks to their adjustable height and rapid deployment. However, choosing a model that is both safe, efficient, and cost-effective requires careful consideration of several key factors.

Define The Application Requirements

  ● Rated load: Determine the maximum working load (including a safety factor) and the load under common operating conditions.

  ● Working height and adjustable range: This includes the minimum height, maximum height, and commonly used height settings.

  ● Span: Measure the worksite's clearance and traffic width to determine the required inner and outer spans of the gantry.

  ● Frequency and purpose: Consider whether the crane will be used frequently for daily tasks or for temporary transport, and whether it will require extended outdoor use.

  ● Environmental requirements: Whether the crane will be used in a cleanroom, food-grade, corrosion-resistant, or explosion-proof environment will determine the material and surface treatment.

Core Parameters and Structural Key Points

  ● Load-bearing structure and materials: Common materials are carbon steel, stainless steel, or aluminum alloy; stainless steel or special coatings are recommended for cleanroom applications. The structure should be stress-checked, and beams and columns designed for bending and torsion resistance should be selected. 

  ● Adjustable Height: Mechanical bolting, electric lift, or screw adjustment. Electric adjustment is convenient and fast, but also more expensive, while mechanical adjustment is less expensive and more reliable.

  ● Casters and Mobility System: Polyurethane wheels are suitable for indoor use, while steel wheels are suitable for rail travel. Pay attention to the caster load capacity and locking mechanism to prevent displacement during operation.

  ● Safety Devices: Limit switches, anti-drop devices, overload protection, emergency stop, and brake lock are essential.

  ● Electrical and Control: Electric hoists are available with variable frequency or single-speed control, and remote/manual operation is available depending on the application.

After-Sales and Maintenance

  ● Choose a supplier that provides spare parts and on-site technical support.

  ● Pay attention to the replacement cycle and interchangeability of wearing parts.

  ● Discuss the need for installation and commissioning, operator training, and acceptance documentation.
