2.4 Point loads
All systems should have minimum of two
anchoring (attachment) points.
One attachment point = one or more fixings
(expander bolts, chemical anchors etc.)
All attachment points of a ceiling lift system
should, according to prevailing standard EN-ISO
10535:2006, withstand a pullout force; the work-
ing load of the system installed times a safety
factor 1,5.
MRS attachment point Load Calculations:
• Molift Lift motors have 5 different weight
capacities within the range: 160 – 300 kg

• Standard ceiling lift system including any
straight rail or traverse system with 1 lift
motor.
• Estimated weight of equipment at pendant
support location for standard system =
approx. 30 kg
(includes: lift motor weight, rails, pendant,
traverse carrier, etc)
• Ultimate Point load for each support
attachment location is based upon the
maximum capacity of the lift motor +
estimated weight of the equipment at the
support attachment location times a safety
factor of 1,5
Example:
For a standard system with 200 kg motor:
200 kg = 200 kg – Safe Working Load
200 kg +30 kg = 230 kg – Working Load
230 kg x 1,5 = 345 kg – Ultimate Point
load
All fixings should always be tight-
ened with torque specified by the
anchor/fixture manufacturer.
