Intended Use
Shears are used for cutting and demolishing steel structures, and preparing bulk scrap for further processing. The shears feature 360 degree rotation and a high force-to-weight ratio. Shears can be mounted on the boom or the stick. Shears can be mounted on a quick coupler or without a quick coupler. Smaller shears can be mounted on Skid Steer Loaders or Mini Hydraulic Excavators.

Shear Capacity
The following table provides an overview of the profiles of steel that can be cut by the shear jaws. The profiles are the most common profiles. The profiles are made of Fe360 (ASTM 283C) steel.
The dimensions of the profiles are the maximum dimension that can be safely cut. Consult your Caterpillar dealer before you cut materials that are larger than the dimensions in the table. Consult your Caterpillar dealer before you cut steel that has a rating that is higher than Fe510 (ASTM A572Gr50).

Out-of-balance Loads
In order to prevent rotation of the shear that is not wanted, you must not exceed the rating for an out-of-balance load.
