18.3.3OPERATIONAL USE

HEALTH AND SAFETY

Always use full protective clothing i.e. Safety Glasses and Gloves.

PREPARING FOR USE

1.Place the anchor point against a support.

2.Releasing

Turn the cable release safety catch (1) and
push the cable release lever (2) towards the
anchor pin until it locks into position when
raised slightly at its limit. Release the safety
catch.

3.Pull through required amount of cable
(Do not overrun cable drum by deploying
too quickly).
4.Anchor machine and cable shackle with
the correct sling.

5.Engaging

5.1Turn the cable release safety catch.

5.2Press the cable release lever vertically downwards, allowing the lever to travel back to its original position under the effects of its spring. Release the safety catch.

6.Take up excess cable.

ANCHORING OF TIRFOR MACHINES

Horizontal or Angle Pulling

The unit can be anchored by its hook, using a sling or a chain, to any fixed point; a ring in the ground or a support column, a rail track, a lorry, a tree, a beam across a door opening or window etc. The Tirfor Ground Anchor is designed to aid rapid anchoring;

Height of Anchorage

For horizontal pulling, or for angles of up to 45E, secure the anchor hook about 150mm above the ground. For angles between 45E and 90E, the recommended height above the ground is 600mm.

Lifting

There are several ways of lifting:-

(a)The most popular is to anchor the Tirfor by its hook to a fixed point as near the ground as possible, and take the cable over a pulley fixed directly above the load. This system is convenient for the operator and keeps him away from the danger of the load.

(b)The Tirfor can be anchored by its hook to a fixed point above the load, and the load lifted toward the machine.

(c)The Tirfor can be anchored directly to the load, and the cable hook anchored directly above it. In this case the cable remains static and the machine and load climb the cable.

Height of Anchorage

For horizontal pulling, or for angles of up to 45o, secure the anchor hook about six inches above the ground. For angles between 45o and 90o, the recommended height above ground is two feet.

LIFTING AND PULLING (See also APPENDIX A)

Tirfor machines can be used for any lifting and pulling job within the rated capacities for the machines. The sketches below show the various ways in which Tirfors are used.

With the operating handle on L1, a to and fro lever action is employed to move the cable through 45mm machine. As the machines do not have ratchets, the operating handle need not be used through its full stroke; if space is confined, short strokes can be made. The handle can be left in any position of its stroke.

When using the Tirfor machine, if the operation is too hard for one person, the work should be stopped and the hauling cable reeved through a snatch block enabling a pull to be made on two parts of the cable. If still too difficult, increase the number of blocks. Never use any other object to replace the telescopic operating handle. Should the...
