MAINTENANCE:
• Clean Rope Grab with water and mild soap. Wipe off with
clean dry cloth. Low pressure compressed air may be used.
• Lubricate with light oil such as WD-40. Use a small amount
of oil on pivot and roller bearing points. Wipe off excess oil
from body and surfaces of the rollers so that oil is not
transferred to the rope.
INSTALLATION AND USE:
• To open the US-5000C pivot the locking clip away from the
body then turn' locking screw Counter-clockwise till
disengaged then pivot open. Inspect as outlined above.
• Position Rope Grab with arrow pointing up (roller attached to
hinge pin will be pointed down)
• Insert the lifeline. Only 5/8" (15.875mm) dia. rope should be
used.. (See LIFELINE section following).
• Pivot the ring so that the gripper does not press against the
rope then close the unit around the rope.
• Tighten the locking screw. It should thread easily and tighten
against the Rope Grab body with both body parts touching.
Rotate the locking dip over the detent (dimple) into the,
notch in the body. It should move easily. and be held in the
locked position by a combination of the detent and bronze
thrust wash-er. Be sure the screw is tight and clip is fully in
the locked position.
• Test mobility: This Rope Grab was designed to function with
a. minimum of effort Move upward by pulling.up on the ring,
the Rope Grab should move easily upwards. Move
downward by lifting up on the ring enough-to release the
gripper and allow the weight of the unit to 'Move the Rope
Grab downwards. Repeat to ensure the freedom of
movement.
• Test the installation by pulling down sharply on the ring to
ensure that the mechanism locks onto the rope. Continued
on other side.
•
WARNING: WHEN IN USE, DO NOT REPOSITION / MOVE THE
UNIT BY HOLDING ON TO THE BODY OF THE ROPE GRAB. IF A
WORKER SHOULD FALL WHILE HOLDING THE ,BODY OF THE
ROPE GRAB THEY MAY BE RESTRAINING THE LOCKING
MECHANISM, RENDERING IT UNABLE TO ARREST THE FALL.
SERIOUS INJURY COULD RESULT. See Diagrams 1 & 2.
• To assist the 'trailing' movement of the Rope Grab the
vertical life line should be held taught by attaching a 6 to 10
lb. weight or by securing the lifeline from below. The safest
method is determined by job site conditions and trained
personnel.
• Rope Grabs are designed for use in a one person fall arrester
restraint system with a maximum weight (person and
equipment) of 400 lbs.
• Anchor point should be capable of supporting a 5000 lb
(22.3kN) load and located directly above the user or twice
the intended load.
• Lanyards should be selected to meet the application with a
5000 lb (22.3kN) tensile strength on all components. ANSI
Z359.1 lanyard or twice the intended load. CSA Z259.2 - a
permanently attached 3 ft (0.6m) lanyard may be installed.
• Never allow rope or rope grab to contact any outside objects
during use. Make sure that your path is free and clear of
obstructions and hazards.
• Positioning the rope grab above user on the life line
minimizes falling distance.
• Calculate fall distance
• Avoid swing falls by working directly below the anchor point
whenever possible.
• If Rope Grab is subject to an arrest it should be removed
from service and discarded.
• After use, inspect as instructed above then clean and store.
