Blocfor® – 50 ft. Self-Retracting Device for Leading Edge with Galvanized Steel Wire Rope

The Blocfor® wire rope self-retracting device provides freedom of movement to workers performing their job at various heights. The device automatically takes up the slack in the wire rope, keeping it out of the way while minimizing the free fall distance, should a fall occur. In the event of a fall, the sudden jerk in the wire rope will activate the centrifugal locking mechanism, arresting the fall within 2 ft. (0.6 m).

FEATURES

• Very lightweight
• Galvanized steel wire rope
• Easy to handle
• Tamper proof connector assembly including carabiner
• Leading edge capability on certain models
• Polyamide 6/ABS
• Sleek and durable housings
• Synchronized twin inertia-braking pawls
• Constant triggering speed regardless of position
• Impact-indicating snap hook
• Rubber recoil bumper
• Features two carrying handles that facilitate the transportation and installation of the device
• Provides freedom of movement at various heights
• Optional swivel at top recommended for horizontal applications
• Capacity 310 lb. (140 kg), one person

HOUSING

• Synthetic case works with the frame to dissipate and absorb shock if dropped or struck by objects

CONSTRUCTION

• Isolated drum keeps all brake components contaminate-free
• All parts are corrosion resistant
• Mechanical parts are not dependent on the integrity of the housing

BRAKE MECHANISM

• Twin stainless steel disc brakes with copper/alloy coil in the centre (all parts are anti-spark)
• Twin inertia and speed-activated brake pawls are designed to activate and engage at the same time. This design compensates against gravitational effects when the block is used horizontally. As a result, the braking system of the blocfor® offers faster reaction

DESIGN

• Features a carabiner-positioning washer
• Rubber stop which is easy to take in hand and acts as a buffer when cable is accidentally released (high-speed recoil)
• Reinforced plastic rope guide is designed for high wear resistance, low cost and easy maintenance
• Swivel self-locking snap hook has a visual fall indicator to allow inspection before each use
