Main technical

 

Mobility & Flexibility

Freestanding design requires no permanent installation

Equipped with lockable casters for easy relocation around facilities

Ideal for multi-site operations or temporary work areas

Space-Efficient Operation

Doesn't require overhead support structures

Fits in facilities with height restrictions where bridge cranes can't be used

Collapsible designs available for storage when not in use

Cost-Effective Solution

Lower initial investment than fixed crane systems

Minimal installation costs - just needs level ground

Reduced maintenance compared to more complex systems

Versatile Load Handling

Compatible with various hoist types (chain, wire rope, or lever hoists)

Can be fitted with specialized lifting attachments (spreader bars, magnets)

Adjustable height (typically 2-6m) and span (3-10m) configurations

Safe & Easy Operation

Stable base design prevents tipping

Includes standard safety features like overload protection

Simple controls require minimal operator training

1. Design & Engineering
Create detailed technical drawings and 3D models.

Perform structural analysis and stress calculations.

Select appropriate materials and components.

Plan production workflow and quality control points.

2. Material Procurement
Source high-quality steel plates, profiles, motors, electrical parts, and accessories.

Verify material certifications and compliance with standards.

3. Cutting & Preparation
Cut steel plates and profiles for main beam, legs, end carriages, and trolley parts using CNC cutting or plasma cutting.

Prepare components by cleaning, deburring, and pre-fitting.

4. Welding & Assembly
Weld the main girder, A-frame legs, and end carriages according to welding procedures.

Use fixtures and jigs to ensure dimensional accuracy and alignment.

Inspect weld quality via visual and non-destructive testing (NDT) methods like ultrasonic or magnetic particle inspection.

5. Machining
Machine critical parts such as wheel seats, motor mounts, and shaft holes.

Ensure precise fitting and smooth operation.

6. Surface Treatment
Clean and sandblast steel surfaces to remove rust and scale.

Apply primer and anti-corrosion paint coatings according to specifications.

Optional: Apply additional layers like polyurethane or epoxy paint for outdoor use.

7. Component Assembly
Install wheels, motors, hoisting mechanism, electrical wiring, limit switches, and safety devices.

Assemble the trolley and hook block.

8. Electrical System Installation
Wire motors, control panels, alarm systems, and limit switches.

Install control mode devices (pendant, radio remote, cabin controls).

Perform insulation and continuity tests.

9. Testing & Inspection
Conduct no-load functional tests for hoisting, trolley, and crane traveling.

Perform load testing with gradually increasing weights up to 125% of rated capacity.

Check all safety devices, alarms, and limit switches for proper operation.

Record test data and certify compliance with relevant standards.

10. Final Adjustments & Packaging
Make any necessary adjustments to mechanical and electrical components.

Clean and prepare the crane for shipment.

Package components securely to prevent damage during transport.
