Securing points
The ability of the ceiling/wall structure to bear the loads applied at the securing points by the
planned system must be assessed. Current standards stipulate that each securing point is to be
able to bear 1.5 x SWL. The current requirements for EACH for ceiling hoist system securing point
are therefore as follows:
Vertical load:
SWL (weight class)
Max load for the hoist
Requirements in accordance
with EN/ISO 10535
The load each securing point must be
able to bear (maximum working load)
160 kg 1,5 x 160 kg 240 kg ≈ 2,4 kN
205 kg 1,5 x 205 kg 307,5 kg ≈ 3,1 kN
230 kg 1,5 x 230 kg 345 kg ≈ 3,5 kN
255 kg 1,5 x 255 kg 382,5 kg ≈ 3,8 kN
300 kg 1,5 x 300 kg 450 kg ≈ 4,5 kN
Table 1. The table specifies the maximum working load requirements in relation to SWL, for
fastener elements used to fit a bracket.
Ceiling hoist systems are to also be able to withstand the lateral loads that are applied when the
patient is in a position of up to 25 degrees from the vertical plane at the very start of the lifting
process.
Horizontal load:
SWL
Max load for the hoist Molift specification
Max allowable horizontal load
in ceilings
160 kg 160 kg x sin 25 ° 68 kg
205 kg 205 kg x sin 25 ° 87 kg
230 kg 230 kg x sin 25 ° 97 kg
255 kg 255 kg x sin 25 ° 108 kg
300 kg 300 kg x sin 25
°
127 kg
