Parker’s Crown Bumper was
designed to replace the existing
wooden bumpers found on many
drilling rigs. The specially designed
elastomeric bumper pads absorb up
to 60% of the kinetic energy created
by a post braking bump of the crown
by the traveling blocks.
The Crown Bumper system has
been tested to withstand a 25,000
lb. “bump” at 3.68 ft./sec. with no
permanent deflection. It was also
tested to withstand a 56,000 lb.
“bump” at 2.94 ft./sec. with only 1/8”
