China made high quality crane outrigger pads

2020-7-22      View:

An outrigger pad is a safety tool that can be used with any equipment that has outriggers, down jacks or stabilizers. 

It is a must for stability when a piece of equipment – such as a crane – lifts loads or personnel aloft. 

This article will provide an overview of outrigger pads, including how to use them safely and 

what kinds of pads are available on the market today.

The Basics
Outrigger pads are placed on the ground under the equipment’s outrigger, shoe, float or foot. 

The size and thickness of the outrigger pads to be used should be selected based upon the type of equipment, 

soil conditions of the work site and type of lift being performed.

When working with outrigger systems, it’s important to understand that the point of contact between 

an outrigger and the ground is quite small. 

Because of the pressure of the outrigger, the ground underneath may shift, be displaced or collapse if an outrigger pad is not used. 

If any of those things happen, there is the potential for the equipment to shift or tip the load, which could lead to the equipment toppling over. 

In fact, approximately half of crane lifting accidents are caused by improper use of outriggers.

Outrigger pads were created to stabilize equipment so that the ground below doesn’t shift and equipment doesn’t topple over. 

Stability is dependent upon the equipment’s footprint and center of mass. 

The footprint is the total area enclosed by the support structure of the equipment. 

The center of mass is the point at which the equipment would balance if it were set on top of a single point to support it. 

If the center of mass is on the edge of the footprint or outside of it, the equipment will topple. 

There are two ways to provide extra stability. 

The first is to use a counterweight to help shift the center of mass back over the footprint. 

The second is to make the footprint bigger with an extendable outrigger system.

All cranes have counterweights, but there is a limit to how heavy they can be due to transportation and setup considerations. 

As noted earlier, the ground can only sustain so much pressure before it gets displaced or collapses. 

Even if you can transport a crane to the work location, there is no guarantee the ground conditions will 

be stable enough to set up and hold the crane. 

Because of that, it is essential for the stability of the equipment to use retractable outriggers to extend the crane’s footprint. 

After deploying the outrigger system, installing outrigger pads underneath the outriggers will 

expand their point of contact with the ground and displace the pressure from the equipment through the outrigger pad to the ground.
