Crown bumper energy management system

产品概况：

Parker’s patented 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 breaking 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” permanent deflection.

Features of the Crown Bumper include:
• Capable of being installed without welding if desired to reduce down time
• Complete with high-strength netting for added safety
• Maintenance-free, extended life elastomer bumper pads
• Each assembly individually serialized for traceability per API requirement
• Two-part epoxy coated metal for corrosion resistance

Typical Configuration:
• Three bars and three elastomer pad assembly
• Standard bar length 30" to 40"
• Modifications available to accommodate attachment span requirements

Standard Materials:
Steel: Three bar (standard) galvanized A3 ERW Type F square steel tubing
Elastomer pads: NR/NBR combination; Temp range -50F to 250F
Nylon safety net: Triple strand nylon netting (not flame retardant) with polypropylene debris net and safety snap hooks

Typical applications:
• Oil and gas drilling rig crown
