SAFETY FIRST
Stabilisers
Stabilisers shall always be fitted when specified.
Attach one stabiliser to each corner of the tower as shown.
Ensure stabilisers feet are equally spaced to form a square.
Telescopic stabilisers must always be fully extended.
Position the lower clamp so that the lower arm is as close to
horizontal as possible. Adjust the position of the upper clamp to
ensure the stabiliser foot is in contact with the ground. Ensure
clamps are secure.
Props
The BoSS StairMAX 700 Mk2 tower shall be adequately propped or tied to prevent lateral movement. They must be fitted
at regular 4.0m intervals. To improve stability, additional props or ties can also be fitted at lower levels.
The method shown below illustrates the use of BoSS Confined Space Stabilisers.
Attach one confined space stabiliser to each corner of the tower as shown (see page 16). Ensure stabiliser feet are
touching the lift shaft walls - adjust confined space stabilisers as necessary to achieve this.
