12. TECHNICAL INFORMATION
12.1 Anchorage and Forces
12.1.1 Mid-Floor - The main force applied to the building structure by the lift is a shear force
through a steel structural beam onto two mid-floor joists either side of the lift. The
maximum force applied to each of the two joists is 3150N. The structural beam is anchored
to the two joists by eight M8 x 60 coach screws.
12.1.2 Lower Level - A maximum horizontal force of 1740N is applied to the lower floor level
of the building via the floor track plate. The floor track plate is anchored to the building
using No.12 x 1½” screws.
12.1.3 Upper Level A maximum horizontal force of 1580N is applied to the building via the
fixings at the top of the tracks.
Where a
ceiling patch
is used, this is anchored to the ceiling joists using No.12 x 3 ½” screws.
The load is spread across a minimum of three joists. The track fixing plate is anchored to the
ceiling patch using No.12 x 1½” screws. Where a wall bracket is used, this is anchored to the
wall using M8 or M10 fixings depending on the wall material.
12.2 Electrical Connection
A dedicated power supply of 230Vac is provided for the lift. The dedicated supply is protected by a
double pole control switch rated at 20A and fused at 10A. The supply is wired back to the main
distribution board where protection of 16A is provided.
12.3 Noise emission
The emission sound pressure level at the user’s position is not expected to exceed 70 db(A).
