2.0 REQUIREMENTS

Consider the following requirements when planning and installing the Powered Climb Assist System:

2.1 FALL ARREST SYSTEM: The Powered Climb Assist System is not certiﬁ ed for Fall Arrest. It must be used in combination with a Lad-Saf™ Ladder Safety System or similar Fall Arrest System certiﬁ ed to the safety standards of the locale of installation.

2.2 LADDER STRUCTURE: The ladder structure on which the Powered Climb Assist System is installed must meet the structural and anchorage requirements of the accompanying Fall Arrest System. See the Fall Arrest System manufacturer’s instructions for details. The PCAS is NOT intended for use with portable ladders or ladders exposed to the environment. Ladders should be nearly vertical with a minimum slope of 75 degrees from horizontal for proper system operation.

2.3 CAPACITY: The Powered Climb Assist System is designed for use by one person with a combined weight (clothing, tools, etc.) of no more than 310 lbs (141 kg). Only one person should be attached to the PCAS at any time.

2.4 ELECTRICAL: The Plug-and-Play Motor Control Unit that powers the Powered Climb Assist System requires a 110-240 VAC, 50-60 Hz power source.

2.5 FULL BODY HARNESS: A Full Body Harness must be used with the Powered Climb Assist System. The harness must have a frontal connection suitable for fall arrest when climbing a ladder. The fall arrest connection point must be above the user’s center of gravity.

RECOMMENDED HARNESSES: Capital Safety recommends speciﬁ c DBI-SALA Wind Energy Harnesses with integrated Climb Assist

Lanyards for use with the 6160026 Cable Grip. Contact Capital Safety or see www.CapitalSafety.com for details.

OTHER HARNESSES: Other harnesses may be used with the 6160024 Cable Grip Lanyard Assembly, but do not offer the same level

of comfort as the recommended DBI-SALA Wind Energy Harnesses.

WARNING: Body Belts are not authorized for use with the Powered Climb Assist System. Falls with a Body Belt may result in

unintentional release or possible suffocation due to insufﬁ cient body support.

2.6 HAZARDS: Use of this equipment in areas with hazards may require additional precautions to prevent injury to the user or damage to the equipment. Hazards may include, but are not limited to; heat, chemicals, corrosive environments, high voltage power lines, explosive or toxic gases, moving machinery, and sharp edges.

PINCH POINTS: Avoid touching areas where

the moving Wire Rope Cable passes through grommets in the Bracket Assemblies when the PCAS is running.

2.7 COMPONENT COMPATIBILITY: Capital Safety equipment is designed for use with Capital Safety approved components and subsystems only. Substitutions or replacements made with non-approved components or subsystems may jeopardize compatibility of equipment and may effect the safety and reliability of the complete system.

IMPORTANT: Equipment substitutions require written consent from Capital Safety.

1 Competent Person: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary,

hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.

2 Inspection Frequency: Extreme working conditions (harsh environments, prolonged use, etc.)may require increasing the frequency of competent person

inspections.

2.8 CONNECTOR COMPATIBILITY: Connectors are considered to be compatible with connecting elements when they have been designed to work together in such a way that their sizes and shapes do not cause their gate mechanisms to inadvertently open regardless of how they become oriented. Contact Capital Safety if you have any questions about compatibility.

Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 5,000 lbs. (22.2 kN). Connectors

must be compatible with the anchorage or other system components. Do not use equipment that is not compatible. Noncompatible connectors may unintentionally disengage (see Figure 4). Connectors must be compatible in size, shape, and strength. Self-locking snap hooks and carabiners are required by ANSI Z359 and OSHA.

2.9 MAKING CONNECTIONS: Snap hooks and carabiners used with this equipment must be self-locking. Ensure all connections are compatible in size, shape and strength. Do not use equipment that is not compatible. Ensure all connectors are fully closed and locked.

Capital Safety connectors (snap hooks and carabiners) are designed to be used only as speciﬁ ed in each product’s user’s instructions. See Figure 5 for examples of inappropriate connections. Do not connect snap hooks and carabiners:

A. To a D-ring to which another connector is attached.

B. In a manner that would result in a load on the gate.

NOTE: Large throat snap hooks should not be connected to standard size D-rings or similar objects which will result in a load on the gate if the hook or D-ring twists or rotates, unless the snap hook complies is equipped with a 3,600 lb (16 kN) gate. Check the marking on your snap hook to verify that it is appropriate for your application.

C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor, and

without visual conﬁ rmation seems to be fully engaged to the anchor point.

D. To each other.

E. Directly to webbing or rope lanyard or tie-back (unless the manufacturer’s instructions for both the lanyard and

connector speciﬁ cally allows such a connection).

F. To any object which is shaped or dimensioned such that the snap hook or carabiner will not close and lock, or that

roll-out could occur.

G. In a manner that does not allow the connector to align properly while under load.

4 – Unintentional Disengagement 5 – Inappropriate Connections

If the connecting element to which a snap hook (shown) or carabiner attaches is undersized or irregular in shape, a situation could occur where the connecting element applies a force to the gate of the snap hook or carabiner. This force may cause the gate (of either a self-locking or a non-locking snap hook) to open, allowing the snap hook or carabiner to disengage from the connecting point.

Force is applied to the Snap Hook.

Small ring or other non-compatibly shaped element

The Gate presses against the Connecting Ring.

The Gate opens allowing the Snap Hook to slip off.
