支腿垫板

Outrigger pads are load-distributing plates used with hydraulic outriggers to increase ground contact area and prevent sinking on soft surfaces.

技术定义与适配语境
典型 支腿垫板 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

Outrigger pads are structural components designed to be placed under hydraulic outrigger feet on mobile machinery such as cranes, aerial lifts, and concrete pumps. They function as load-spreading interfaces between the outrigger shoe and the ground surface, reducing ground bearing pressure to prevent soil failure, equipment tipping, or structural damage. These pads are engineered to withstand compressive forces while maintaining stability on various terrain types including asphalt, concrete, grass, and uneven ground.

定义
Outrigger pads are structural components designed to be placed under hydraulic outrigger feet on mobile machinery such as cranes, aerial lifts, and concrete pumps. They function as load-spreading interfaces between the outrigger shoe and the ground surface, reducing ground bearing pressure to prevent soil failure, equipment tipping, or structural damage. These pads are engineered to withstand compressive forces while maintaining stability on various terrain types including asphalt, concrete, grass, and uneven ground.
工作原理
Outrigger pads operate on the principle of pressure distribution. When hydraulic outriggers extend to stabilize equipment, the concentrated load from the outrigger shoe is transferred to the pad, which spreads this force over a larger surface area. This reduces ground pressure below the soil's bearing capacity, preventing sinking and maintaining equipment stability. The pad's rigid structure ensures even load distribution while its surface texture provides friction to prevent lateral movement.

常见问题

What surfaces require outrigger pads?

Outrigger pads are essential on all surfaces with insufficient load-bearing capacity including asphalt, concrete near edges, grass, soil, sand, gravel, and uneven terrain. They should always be used unless operating on engineered concrete pads specifically designed for the equipment's load.

How do I determine the correct pad size for my equipment?

Calculate required pad size using: Pad Area = (Outrigger Load × Safety Factor) ÷ Ground Bearing Capacity. Consult equipment manufacturer specifications for maximum outrigger loads and always include a minimum 2.0 safety factor. Professional engineering assessment is recommended for critical applications.

Can outrigger pads be stacked for additional height?

No, stacking pads is not recommended as it creates instability points and uneven load distribution. Use specifically designed outrigger extensions or blocking systems if additional height is required. Always maintain a single, solid interface between outrigger and ground.
