Mobile tower scaffolds provide a very useful and efficient working platform for
numerous tasks when used properly. When misused, they provide a means of
serious injury to both users and other employees.
Main Points
• Plan use of mobile tower scaffolds. Ensure SWL’s are sufficient, that manufacturer’s
guidelines are complied with, and that a competent person is available to erect, adjust and
dismantle.
• Check all mobile tower scaffolds prior to use; check general condition, check
Brakes/locking devices are working, check free rotation of wheels, check all bracings are in
place, check for suitable access/egress and for suitable platform.
• Where height exceeds 2m then guard-rails, intermediate guard-rails and toe boards must be
fitted (note this is a minimum requirement – recommended that they be fitted regardless of
height).
Discussion points:
• Check manufacturers guide for base to height ratio. General rule is that the height should not
exceed 3 times the narrowest base width, i.e. where narrowest base width equals 1.5m,
height should not exceed 4.5m. (Note: this can be extended by use of outriggers.)
• Mobile tower scaffolds should only be used on level, firm surfaces. If surface is soft or not
level then should only be used where adequate support is provided.
• Wheels should be locked whenever the tower is in use. Only integral ladders should be used
– on no account rest ladders against outside, or use ladders off of mobile tower platforms.
• Ensure all persons and materials are removed from mobile tower scaffolds prior to moving,
move by pushing at the base, avoid potholes/uneven surfaces, and beware of overhead
obstructions – especially power lines!
• Mobile tower platforms should be fully boarded out where practicable – must be a minimum
of 600mm wide.
• Consider tying the tower to structures where applicable.
