Surespan Zip 8 Ladders
Read and follow these instructions with care before you install the Zip ladder.
(Units are heavy; safety should be observed at all times)
Zip Ladders with steel casing
1. Check the following measurement; length and width of aperture, depth
of ceiling, length and width of steel casing, height of the steel casing.
Ensure the dimensions of the aperture, on each side are 5mm larger
than the casing.
2. Bring steel casing (2) from below of opening into fixing position. Install
the parts 6, 7, 8, 9 (see diagram A). Fit screws M16 x 160 (8) on all four
corners and secure in the given box sections. Caution: do not turn
screws (8) in too deeply, as they will need to removed later. Lift up the
hatch and swing the bracket (6) over the fringe of the steel casing and
floor. This provides support to keep the casing in a stable situe.
3. Fit strong enough cable on all four corners on the brackets (6) with
shackles (9) (see diagram B) and pull the casing up into the aperture.
Caution: lift up the casing with care.
4. Swing brackets (6) to the outside over the edge of the steel casing and
floor to give support and prevent the casing falling down. For extra
safety, temporarilly fit brackets to the corner pillars for added support.
Make sure the trap door can be opened for adjustment.
5. Fix wooden spacers (3) (see diagram. B) between casing and aperture at
the places the screws are planned.
Zip Ladders with wooden casing and trap door ceiling
1. Place the wooden casing (5) central in the aperture opening. From
above, use wooden batons (3) (not supplied by Surespan, 30 x 30mm)
fixed to the casing (5) with screws (1) for wood (min. Ø 4.5 x 70) to aid
with lowering the casing into the aperture opening. Ensure the casing
is square and level with the ceiling level below.
2. Fix wooden spacers (4) between the casing and aperture using screws
(min Ø 4.5 x 70). As shown in diagram.
3. Install the casing (5) with screws (min. Ø 6 x 70) in suitbable places
(see diagram). Minimum of 6 screws to be used.
4. Check the correct operation from landing below by opening trap door.
5. Fill the gap between the casing and aperture with insulation material.
6. Fix cover strips with nails (1.8 x 35mm) or ceiling tiles to the
underside of the trap door.
