Outrigger pads and crane pads are the foundation of safety in construction workplaces. They are the basis for the stability of a crane setup in any kind of ground conditions. Outrigger pads must match the weight and pressure of the set up. The size of the pads is important when it comes to providing a stable base. Tough and reliable outrigger crane pads are an essential safety item in a number of industries like construction toon, mining materials utilities etc.
Safety standards for outrigger crane pads
The U.S. OSHA defines the conditions for the assembly of cranes. The ground should be firm, drained and properly graded. Supporting materials like blocking, cribbing, pads, and mats should be used for support and to level the ground if needed. These guidelines are set out in OSHA 1926.1402.
Further, ASME provides the standards for outrigger blocking or cribbing. It must be strong enough to prevent crushing, bending, or shear failure. The size, in terms of thickness, width and length should completely support the float and transmit the load to the supporting surface. It should prevent shifting, toppling or excessive settlement. These guidelines are outlined in ASME B30.5-2011.
A better crane outrigger pad
The purpose of outrigger pads is to distribute the load from the outrigger float. They should stay level when the load swings, to keep the crane stable. Crane pads should be suited to handle the amount of pressure they will bear during operations. Crane outrigger pads should meet or exceed the bearing, flex and shear strength.
Newer outrigger pads are made from an engineered thermoplastic, which is a much better alternative than wooden or steel crane pads. The plastic is dense and strong and will not buckle or shear. It is lighter than steel and more stable than wood. Newer crane pads made of thermoplastic meet the need for operating in different ground conditions, ease of use, weight, ergonomic safety and lifespan.
Getting the right size
It’s important to use the right size crane pads for every operation. If they are too small, the operation can become unstable. Crane pads that are too large for the job are wasteful in terms of price, as well as labor and transportation costs.
When choosing the right size, a number of factors should be taken into account, including ground conditions and ground bearing capacity.
Outrigger crane pads are crucial to safety in a number of industries like construction, maintenance, electrical utility, mining, oil and gas and tree care as well as government and military. Meeting OSHA and ASME standards for rigging and cranes is an essential safety measure on these work sites.
