Where it is necessary to erect a scaffold that does not start from the ground, a
cantilever scaffold can be used. The construction of cantilever scaffolding
consists of two scaffold tubes supported between the floors & ceiling by means of
a base plate at the top and a screw jack base plate on the floor.
The scaffold tubes (called Puncheon tubes) are securely adjusted to from a rigid
support for the cantilever. It is important to fix sole plates at the top & bottom of
the puncheon tubes for uniform distribution of load over floor and ceiling.
Additional ledgers are laid under cantilevers to provide supports to the working
platform. Moreover further additional support can be provided by using raker
tubes. An independent scaffold should have a safety fitting, which can be
fastened below any critical fitting.
F. Swinging Scaffolds:
For swinging scaffolds the decking & handrails must be supported by metal
hangers regardless of the type of platform. Such scaffold should be equipped with
guardrail of height not less than 915mm or more than 1145mm from the platform.
The guardrail should be a dressed timber not less than 50mm x 75mm in cross
section. It should be supported in a loop formed in the hanger and securely
fastened preventing any displacement. The toe boards should be not less than
140mm in height, which is securely fastened to the outer edge of the hanger.
The ropes supporting swinging scaffolds should be made of finest grade manila
fibre, not less than 20mm in diameter. It should be properly rigged into a set of
standard 150mm blocks, consisting of at least one double and one single block.
Swinging scaffolds should be properly hung from secured supports equipped
with hooks of sufficient strength to provide a safety factor of at least 4:1.
Swinging scaffold hooks should be tied off with at least 25mm diameter manila
rope secured to a stable roof mounted structure.
Where steel cables are used, it should be less than 15mm in diameter alongwith a
hoisting mechanism provided at the end of the scaffold platform. There must be
at least three turns of wire rope left on the cable drums during hoisting or
lowering.
It is not permissible to allow more than two persons at a time on a swinging
scaffold. Each person working on a swinging scaffold should wear safety belt and
lifeline extending from roof to the ground. The safety belt should be tied to the
lifeline with a triple sliding hitch or with a mechanical rope grab.
When load testing the scaffold for its intended maximum weight, the decking
should be more than 450mm from the ground.
G. Rolling Scaffolds:
All caster brakes should be locked when the scaffold is in its working position.
The height of the working platform should be never be more than 3 times the

smallest base dimension. The guardrails must be provided for such scaffolds and
moreover leg-adjusting screws should not be in a fully extended.
The workers are not allowed to ride a rolling scaffold when it is being moved. It
is to be ensured prior to using such scaffold that it is completely upright, level
and caster on a firm base.
H. Ladders:
The ladders must have adequate strength, and capability to bear the load intended
to support safely. The ladder with missing or defective rungs must not be used.
The wooden stiles, sides and wooden rungs should have running grained along its
length. The rungs shall be properly fixed to stiles or sides and should not be
painted or treated to cover the timber defects. The rungs should have
reinforcement ties in case the tenon joints are not secured by wedges.
The ladder, which is not standing on a firm base, must be secured properly by
uniform suspension at each stile or side to prevent undue swinging. Similarly the
ladder, which is standing on a firm base, must be properly supported on each stile
or side and also duly secured at the upper point of rest. If such fixing is
impractical, a person must be stationed at the foot of the ladder to prevent
slipping. The ladder shall have a non-skid type shoes to prevent slipping.
The recommended angle to set a ladder is 14° from the perpendicular.
Consequently the distance between the foot of the ladder to the point immediately
below the upper support should be equal to one quarter of the height. The ladder
must rise to a height of at least 1050mm above the landing place or above the
highest approachable rung, except in case of adequate handholding support at the
landing location.
The spacing at each rung should be sufficient to provide adequate foothold. A
landing place of adequate size should be provided if practicable every 9.0 meters,
(30 feet) of vertical distance or more often. The landing place (from which
persons are liable to fall from a height of more than 2 meters) should be provided
with hand rails of height between 915mm to 1143mm alongwith toe boards to a
height of at least 200 mm. The space between guardrails and toe board should not
be more than 762 mm.
1. Ladder Scaffolds:
The ladder scaffolds should be used for only light work and materials
permitting safe use. These ladders should have adequate strength and
stability to prevent collapse & slipping.
2. Gangways & Runs:
The gangways being used for passage of materials should be wide enough
for the purpose. However the gangways must be at least 430 mm wide if
it is to be used for the passage of persons through it.
