APPLICATIONS
A. 1
PURPOSE:
The N610LY, N630LY rope grabs are intended to be used as part of a personal fall arrest system. Applications
for these rope grabs include most activities where there exists the need for fall arrest or restraint (on sloped surfaces)
Figures 2 and 3 are examples of these applications. This rope grab is a part of a complete fall arrest system, including
approved lifeline (only lifelines listed in these instructions can be used), integrally attached shock absorbing lanyard
(supplied with N610LY, N630LY – only these shock absorbing lanyards can be used) and full body harness. Maximum
permissible free fall is 1.8 m (6 feet). The rope grab can ONLY be used with the supplied integrally attached shock
absorbing lanyard.

LIMITATIONS:
Always consider the following limitations and requirements when installing or using this equipment.
a
CAPACITY:
The N610LY and N630LY rope grabs with integrally attached shock absorbing lanyard are designed for use by
persons with a combined weight (person, clothing, tools, etc.) of between 45kg (100 lbs) and 160 Kg (352 lbs) NOTE: No
more than one person may be attached to a single lifeline.
b
FREE FALL:
Fall Protection / Restraint systems must be rigged such that there is no possible vertical free fall. The N610LY
and N630LY rope grabs can only be used with the supplied, integrally attached shock absorbing lanyard and the system
must be rigged to limit the free fall to 1.8 m (6 feet) or less per (CSA Z259.2.5). See associated connecting subsystem
manufacturer’s instructions for additional information.
c
FALL CLEARANCE:
Make certain that enough clearance exists in your fall path to prevent striking an object. The amount
of clearance required is dependent upon the type of connecting subsystem used, the anchorage location, and the amount
of stretch in the lifeline, free fall distance, and deceleration distance.
d
CORROSION:
Do not leave this equipment in environments where corrosion of metal parts could take place (i.e. as a result
of vapors from organic materials, sewage and fertilizer plants, corrosive chemicals, etc). Use of these rope grabs near
seawater or other corrosive environments may require more frequent inspections or servicing to ensure corrosion
damage is not affecting the performance of the product.
e
CHEMICAL HAZARDS:
Exposure of these grabs to corrosive or caustic liquids may cause damage to this equipment and
affect is safe use. When working with such chemicals, frequent inspection of this equipment must be performed. Consult
Yoke Industrial if there is a doubt concerning use of N610LY, N630LY around chemical hazards.
f
HEAT:
The N610LY, N630LY are designed for use in high temperature environments. Protection should be provided for
this equipment when used near welding, metal cutting, or similar activities. Hot sparks may burn or damage this
equipment and affect its safety.
g
ELECTRICAL HAZARDS:
Due to the possibility of electric current flowing through this equipment or connecting
components, use extreme caution when working near high voltage power lines.
