Available in 2" to 12" Dia. Steel Base designs have a steel base plate with 4 bolt holes, bonded to the cylindrical bumper. They are available from 2" Dia. up to 12" Dia. Econo Bumpers are available with a bolt molded to the base. All Crane Bumpers comply with C.M.A.A & O.S.H.A. requirements.
"P" Series Crane Bumpers
Poly-Pro "P" series Crane bumpers are made of single piece molded Polyurethane bumper body with integrally molded base, with reinforcing expanded metal screen(s) molded inside the base.
