The Garlock Life-Link Cart is a roofing fall protection system for up to 3 contractors working at or near a roof edge. It is only intended for work performed on flat, level roofs with a maximum pitch of 0.5 in. over 12 in. (0.5:12).
The Life-Link has been tested and approved for:
- Fall arrest—Stopping a worker after he or she has fallen off a roof, or
- Fall restraint—Preventing a person from falling over the edge.
Specifically, the Life-Link Cart is approved for use on the following substrates:
- Built-up roofing systems (BUR)
- PVC / TPO / EPDM fully adhered and loose-laid membranes
- 20 gauge and 22 gauge metal decks
- Adhered plywood and hardwood decking
- 4,000 PSI lightweight concrete (2-person fall arrest ONLY)
In this post, we’ll detail the steps to properly hoist, set up and safely attach to the Garlock Life-Link Cart. While this information was taken from Garlock’s operating manual, Hy-Tech Products recommends that every contractor working with the Life-Link Cart read through the manufacturer’s instructions carefully before using.
Hoisting the Life-Link Cart to the Roof Deck
Before hoisting the Life-Link Cart to a roof deck, make sure that the roof can support the cart’s weight (1,000 lbs.) in addition to all material, equipment and personnel. Weak roof decks under this type of stress can collapse.
To hoist the Life-Link, use an OSHA-approved 4-point sling with a minimum-rated capacity of 2,000 lbs. Hook all four sling connection points onto the four cart lift lugs (1 connection point to 1 lug lift) (see right).
When attached, the sling’s chains should be long enough not to press against the cart. If they are too short, you will need to purchase longer changes as the stress put on the chains by the cart’s weight may cause damage to the cart or cause the sling to fail.
Cart Set Up and Positioning
On the roof deck, remove all debris, loose roof coverings, and any ice, snow, water, oils, dirt or dust from where the cart will be positioned, as these may prevent the cart from locking in place.
Next, perform a pre-use inspection using the Inspection Label on the side of the toolbox.
To set up the Life-Link Cart:
- Make sure there is nothing obstructing the pull plate (square green plate that the green attachment rings are secured to) from extending forward, and that the claw can swing down directly into the roof deck should someone fall.
- Align the cart so its side runs parallel to the roof edge and is a minimum 15 feet (no less) away.
- Position it straight back from the work area (see right).
- Make sure the cart handle points straight forward, and the angle brake (perpendicular bar located near the end of the handle) engages the tires to keep them from rolling.
Attach Contractors to the Life-Link Cart
When attaching contractors to the Life-Link Cart, use only self-locking snap hooks and carabineers that are specifically designed for fall-protection devices.
The Life-Link Cart includes two types of attachment rings.
- Yellow Rings (2 total): Use these rings when kneeling behind the roof edge. Adjust the length of the lifeline so the worker’s shoulders cannot extend over the roof edge. (Top Right)
- Green Rings (3 total): Use these rings when working at the roof edge. Attach only one lifeline to each ring, and the lifeline should be adjusted to be no more than 2 feet longer than the distance from the cart to the roof edge. (Bottom Right)
When attaching snap hooks and carabineers to either rings, make sure all closures are fully closed and locked in place.
While attached to the Life-Link Cart, make sure the angles of lifelines to the cart are no more than 45°. Venturing past this “safe zone” could cause serious injury or death should the worker fall.
