METAL CONDUCTS ELECTRICITY
Do not use this equipment where contact may be made with power lines or other live electrical circuits.
OPERATION AND SAFETY
Do not use this equipment if you are in poor health, taking medications, drugs, or have
been consuming alcohol, all of which may impair your ability to work safely on this
product.
All equipment must be inspected before use to ensure the integrity, good repair, and
suitability for intended use.
Inspect before use. Do not use this scaffolding if damaged or parts are missing.
Always use this scaffolding in conformity with local or national legislation
which applies.
A scaffolding must be erected, altered, and dismantled by qualified workers or under
the direct supervision of a qualified person.
The base must be firm and level enough to support the load of scaffolding, workers,
and materials. Sills and base plates are required on soil and unstable ground, or
where any leveling adjustment is needed. The sill must be sound, rigid, and capable of
supporting the maximum loads without settlements or deformation.
Leveling jacks must be adjusted within the limits specified by local regulation.
Frames must be plumb, level and spaced to adequately support loads.
Always install inner and outer handrails to the stair before using the stairway.
Upper adaptable handrail post MUST be secured at the correct compatibility position
to the handrail with bolts.
All handrails MUST be secured to the stair with bolts or locking pins before
using the stairway.
ALWAYS secure both ends of the stair to the scaffolding structure with bolts (TOP and
BASE) to prevent lifting of the stairway.
To prevent the scaffolding from overturning, scaffolding MUST be tied to a building or
structure using wall attachments or guyed when built above the 3:1 ratio. Guying or
tying a scaffolding may require the direction of a professional engineer.
Wall attachments MUST be used to ensure stability for heights exceeding the 3:1 ratio.
Wall attachment must be installed at every 15 ft in height and every 21 ft in length of
the scaffolding structure.
All workers MUST be protected from falls by guardrails or a personal fall arrest system
when working at 10 ft from ground or more.
Guardrails must be installed on all open sides of the platform where a person could
fall a distance of 10 ft. or more. The top rail must be placed 40-44 in. above the work
surface. An intermediate rail must be placed halfway between the top rail and the work
surface. DO NOT STAND ON OR PLACE LOADS ON GUARDRAILS.
STAIRWAY CAPACITY
Uniformly distributed load: 800 lb (363 kg)
Point load applied at the center of any stair tread: 495 lb (225 kg)
SAFETY FACTOR 3:1
FAILURE TO UNDERSTAND AND FOLLOW ALL SAFETY RULES AND ASSEMBLY
INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.
WARNING
1
Work Planning
1)
Evaluate the position of the stairway based on access, soil capacity and
possible anchor points;
2)
Depending on the local or national legislation, an installation plan sealed
by a professional engineer may be required;
3)
Forming a team of at least three competent workers able to assembly a
scaffolding; (1 equipment provider & 2 assemblers).
2
Protective Equipment
Workers MUST always wear their equipment on a construction site.
1)
Protective helmet, safety boots, protective goggles & gloves;
2)
Full safety harness complying to local regulations;
3)
Life line & anchor points complying to local regulations;
3
Preparation before assembly
1)
Secure the work environment with ribbons or job site fence
to limit access.
2)
Install vertical lifelines, one per worker.
3)
Ensure that the equipment does not fall when properly installed.
4
Assembly
1)
Place the sills (planks) on the ground to distribute the loads.
2)
Install four leveling jacks on the planks and adjust the level
to compensate irregularities of the soil.
3)
Install the stair starting tube on two of the leveling jacks
(starting point of the stairway).
4)
Install the first arch frame on the starting tube.
5)
Install two cross braces to the first arch frame.
6)
Install the second arch frame on the other leveling jacks, connect it to
the cross braces.
7)
Adjust the levels, nail the jacks to the planks placed on the ground,
check the perpendicularity of the base.
8)
Install the service platforms (not included) at every story on the top
horizontal tube of the arch frames.
9)
Install the next two arch frames to the lower frames using coupling pins
and pigtail locks.
10)
Connect the two arch frames with cross braces.
11)
Repeat steps until the final installation of the access tower to the desired
height.
12)
Always Install wall attachments every 15 ft in height (3:1 ratio).
13)
Install lifting system at the top of the access tower; hoist post, gin block
pulley and lifting cable.
14)
Bring up the stairs starting at the top of the tower.
15)
Finish the installation with the stairs at the bottom.
16)
Secure both ends of the stair units to the scaffolding structure with bolts
(top and base).
17)
Install inner and outer handrails to the stairs, secure it to the stairs using
bolts or locking pins.
18)
Install adjustable end-stop guardrail to every arch frame at the upper
point of a stair unit (one by story).
19)
At the top of the access tower install the guardrail system.
20)
Secure the guardrail and deck installation by making sure there is no fall risk
