What size outrigger pads do I need?
A Rule of Thumb An outrigger pad should be at least three times the square surface area of the outrigger shoe or float, provided you are working on Grade A soil conditions.
Does OSHA require outrigger pads?
According to OSHA, safety is always a requirement. OSHA 1926.1402 states that, in all instances in which a crane or other lifting equipment is used, the ground on which the equipment is placed must be firm, sufficiently drained, properly graded, and able to support blocking, cribbing, and outrigger pads.
What are outrigger pads made of?
polyethylene
Industrial plastic outrigger pads, like the ones engineered here at Cope Plastics, are made from an extremely tough polymer called UHMW (ultra high molecular weight) polyethylene. There are several reasons why UHMW outrigger pads outperform those made of hardwood.
What is the purpose of outriggers on cranes?
When you operate a crane truck, you also operate hydraulic or manual outriggers. Outriggers keep your truck stable during any kind of lift by extending outward and making contact with the ground several feet away from the truck. This provides a solid, stable base by distributing the crane’s load over a larger area.
How do you measure crane pads?
Crane mat size can be calculated by dividing the crane load by the maximum permissible ground pressure.
Are crane outrigger pads required?
Some believe setting up on concrete or asphalt would be safe and you may not need outrigger pads. However, it is recommended to always use outrigger pads under crane floats to distribute ground pressure just in case there is an open cavity or unseen voids,” says Billy Smith EVP of Claims and Risk Management of NBIS.
How do outrigger pads work?
An outrigger pad is either wood, metal, or a synthetic flat structure that is placed on the surface to provide support for the outrigger feet. Outrigger pads are mainly used under the outrigger feet to ensure a stable surface and work to prevent ground damage from the heavy load pressure.
What is an outrigger mat?
Placed under a crane’s outrigger feet, these strong and durable protection mats spread the load to create a more stable lifting base and to reduce floor loading. Manufactured in high resistance polyethylene, the size of the mat require will vary according to the working environment and point loadings.
Do outriggers need to be fully extended?
Use The Correct Load Chart: The purpose of outriggers is to improve the stability of the crane. Accurate use of the “on-outriggers fully extended” load chart, requires that outriggers be fully extended and they must bring the rig completely off-rubber.
What is the difference between stabilizers and outriggers?
Stabilisers and outriggers have many configurations depending on the application and are used to minimise the risk of toppling when the centre of gravity of the combined load and vehicle is outside the support base of the vehicle. Outriggers lift the vehicle’s wheels off the ground while stabilisers do not.
What is the standard size of outrigger pad?
There are many different sizes and styles, but the following four are the most common ones for sale: Outrigger Pad 4 x 4 Ft x 2 Inch. Outrigger Pad 3 x 3 Ft x 2 Inch. Outrigger Pad 2 x 2 Ft x 2 Inch.
