The key to building a crane outrigger pad is to choose the right materials, design a reasonable structure, and ensure sufficient load-bearing and safe use. The following is a detailed production process and technical points.
- What are the materials suitable for homemade outrigger pads?
Material Features Recommended
UHMW-PE sheet High strength, impact resistance, wear resistance, waterproof, non-slip, light weight Strongly recommended (high-end)
HDPE sheet Low cost, medium strength Recommended (medium load-bearing)
Steel plate Ultra-high strength, but heavy and easy to rust Only for fixed use sites
Hardwood board (multi-layer plywood) Easy to process, but easy to absorb water and short life Not recommended (unsafe)
II. Construction steps of crane leg pads - Select material thickness and size
Choose the appropriate sheet size according to your crane tonnage:
Crane tonnage Recommended size (L×W×T, mm)
Within 10 tons 400×400×30
Within 25 tons 500×500×40
Within 50 tons 600×600×50
Above 100 tons 800×800×60–80
It is recommended to use UHMW-PE (molecular weight above 3 million) for the sheet, and the weight of a single piece is about 10–25 kg, can be carried manually. - Processing and shaping
Use sawing machine or CNC to cut the plate:
Ensure square or rounded rectangle, the edges can be rounded (to prevent scratches);
If it is a multi-layer structure (such as stacking), it can be reinforced with screws or hot melt welding.
Optional hole design (for easy handling):
Open an elliptical hand hole (80×25mm) on one side;
Or make a rope hole with a diameter of 25–40mm to pass the traction rope. - Surface treatment
Process the surface texture or cross anti-skid groove to improve grip;
Rubber pads, aluminum nails or anti-skid stickers can be added to the back to prevent slipping;
Engrave the logo, number, and load-bearing tonnage information for easy management. - Check the load-bearing performance (basic test)
The maximum static pressure can be tested with a jack or a pressure plate;
Ensure no deformation, cracking, or slipping. 3. Precautions for self-made
Project Key points
Material selection UHMWPE is recommended; do not use ordinary plastic or wood
Size matching crane Too small will not bear enough pressure, too large will be difficult to carry
Sufficient thickness At least 30mm, heavy duty requires 60mm+
Surface non-slip design Increase safety, especially on wet ground
Stackability Suitable for height adjustment on uneven ground
