Product Description
 
Insulated Buckets
Two parts of an insulated bucket truck, the bucket itself and the boom, have a dielectric fiberglass coating. This prevents electricity from flowing through the boom, damaging the equipment, or potentially electrocuting the operator. Typically, a boom has 3 insulating areas: one in the lower boom, one in the upper boom, and one in the bucket liner. All have different insulation ratings.
The fiberglass component certainly raises the price of the unit, whether it be new or used. But for industries like utilities, where linemen are repairing and maintaining power lines, the safety is well worth the price.
