ANCHORING
Failure to anchor the tirfor
®
machine correctly runs
the risk of a serious accident. The user must always
ensure before operation that the anchor point(s) for
the machine and wire-rope are of sufficient strength
to hold the load.
It is recommended that tirfor
®
machines should be
anchored to a fixed point or to the load using an
appropriate capacity sling.
It is forbidden to use the
machine’s wire rope as a sling
by passing it around
the load and hooking it back onto itself (Fig. 10.1:
incorrect anchoring arrangement; Fig. 10.2: correct
anchoring arrangement).
The anchoring arrangement of models TU
™
8 and TU
™
16
is a hook fitted with a safety catch (Figs. 11 and 12).
In all cases when anchoring the machine the safety
catch of the anchor hook should be correctly closed,
in its position at the tip of the hook (Fig. 12). This advice
for the machine anchor hook also applies to the hook
fitted to the wire rope.
tirfor
®
machines TU
™
32 and T500D are anchored by
means of a removable anchor pin, fitted across the two
ends of the side cases (Figs. 13 and 14) and locked in
position by a spring clip (Figs. 15 and 16).
Optional hooks are available to fit the anchor point of
models T500D and TU
™
32.
To anchor using the anchor pin, follow the procedure
below:
1. Open the spring clip of the anchor pin.
2. Remove the spring clip from the anchor pin.
3. Slide the anchor pin out of the side cases (Fig.14).
4. Fit the anchoring arrangement, such as a sling,
between the side cases.
5. Refit the anchor pin through the side cases and
anchoring arrangement, such as the eyes of a
sling.
6. Refit the spring clip to the anchor pin.
7. Close the spring clip, ensuring that it fits correctly
over the end of the anchor pin and cannot fall out.
WARNING:
It is essential for the safe operation of
the machine to ensure that, before loading the machine,
the anchor points, hooks or pins, are correctly secured,
(with the safety catch correctly located on the hook -
Fig. 12).
6. OPERATION
tirfor
®
machines are very easy to use. Place the
telescopic operating handle on either the forward or
reverse operating lever, lock it into position by twisting,
and move the operating handle to-and-fro. The operating
arc is variable for ease of operation.
When operation stops, both jaws automatically grip the
wire rope and hold the load which is spread equally
between the jaws.
The to-and-fro operation of the forward or reverse lever
gives continuous movement of the load.
7. DECOMMISSIONING AND STORAGE
It is essential to take the load off the machine before
attempting to release the jaws.
To do this, operate the
reverse operating lever until there is no tension in the
wire rope.
Remove the telescopic operating handle and return it
to the closed position.
Release the jaw mechanism and follow the
instructions for installing the wire rope in the reverse
order. Re-engage the jaws of the machine before
putting it into storage.
Store the machine and wire rope in a dry place, away
from the effects of the weather. The wire rope should
be completely removed from the machine and rewound
onto its reeler.
Before reeling the wire rope, it is recommended to
inspect it, clean it with a brush and then grease it
(see section 10: “Wire rope”).
