Safety Notes
ERECTION & DISMANTLING - THE 3T(through the trap) METHOD
Towers should be erected following a safe method of work, there are two approved methods recommended by
‘Prefabricated Access Suppliers & Manufacturers Association’ (PASMA) in co-operation with the Health and Safety
Executive (HSE) & the “working at height regulations 2005”
The method used for erecting and dismantling the UTS 1450/850 tower is the 3T METHOD (through the trap).
This method ensures the operators erecting the tower position themselves in the trapdoor of the platform to add or
remove horizontal guardrail braces for the level above the platform.
NEVER STAND ON AN UNGUARDED PLATFORM.
Before assembly or erection of this Mobile Access Tower (MAT) please ensure that:
• A risk assessment has been done and all safety equipment is on site.
• The ground conditions will take the working loads of MAT as specied.
• Always check that the MAT is vertical, (Level, slope, uneven ground etc.) if levelling is required make sure you
adjust legs , in line with instructions (use spirit level).
• Beware of (overhead) obstructions – live wires, electrical apparatus or moving parts of machinery or other.
• Wind conditions are within limits as specied. (Refer to page 6)
• Do not use boxes, ladders, or other devices on the platform to gain additional height.
• If in doubt DO NOT ERECT.
• Check that all components are on site and that they are in good working order before use (refer to the
components and quantities shown at each stage). Auxiliary equipment and safety equipment. (ropes, etc)
• All platforms MUST have horizontal guardrails tted.
• The tower should always be accessed from the inside using the ladder frames provided.
• Never climb up the outside.
• Do not use the guardrail braces as a rung or step.
• It is recommended that 2 persons erect this tower.
• The assembled tower should not be used as a means to enter or exit other structures, e.g. as a stair tower.
• Beware of horizontal forces (e.g., when using power tools on an adjacent structure), which could generate
instability or overturning of the tower.
• Maximum distance between platforms is 2.25m, maximum distance to the rst platform is 3.4m.
• Maximum horizontal force 20kgs.
• Mobile access and working towers are not designed to be sheeted
• The tower height used should be appropriate for the working height, e.g. within 2 meters above the platform

Page 5UTS SALES & REPAIRS LTD
• User training courses cannot be a substitute for instruction manuals but only complement them.
• Only the original UTS components specied in the manual shall be used.
• Mobile access and working towers designed in accordance with BS EN 1004-1:2020 are not anchor points for
personal fall arrest equipment.
• Working is only permitted on a platform with a complete side protection including guardrails and toe boards.
• Mobile access and working towers are not designed to be used as edge protection.
STABILISERS & BALLAST
Stabilisers or outriggers and ballast shall always be tted when specied. When using the MAT externally stabilisers
must be tted. Should ballast be required, a platform should be positioned on the lowest rung and the weights should
be rmly attached to it and evenly distributed. For advice on ballast contact your supplier.
LIFTING OF EQUIPMENT
Tools and other equipment should be hauled up by a person on the platform using rope or similar, through the
trapdoor of the platform or within the tower footprint.
Please see footprint guide on page 16.
Safe working loads of platform and tower not to be exceeded.
MOVING THE TOWER AND LEAVING IT UNATTENDED
• Adjust the stabilisers to provide ground clearance.
• Unlock the castor wheels.
• Move with manual force only, and only from the base.
• Beware of (overhead) obstructions – live wires, hanging apparatus or other objects.
• Do not move with people or material on the tower.
• Do not move the assembled MAT if wind speeds exceed a moderate breeze. Relock the castors and readjust
the stabilisers once in the new position.
• When moving the tower over uneven or sloping ground remove all tools.
• Do not move the assembled tower if over 4 meters high.
• Recheck that the MAT is vertical or needs readjustment of legs before ascending. (Using spirit level)
• Mobile access and working towers shall only be moved on a at and solid ground without obstacles and not on
a slope of more than 10mm/1m
It is recommended that towers should be tied to a solid structure, when left unattended.
TIES
When ties are required, they should be in accordance with table 17 of BS 5973:1990 and table 24 of BS 5975:1982.
Always tie to a solid structure.

CHECK LIST, INSPECTION CARE AND MAINTENANCE FOR MOBILE
ACCESS TOWERS
• All components should be inspected before use to ensure that they are not damaged or broken,
particularly the welds.
• ANY damage to ANY part particularly tubular members, castors, platform decking MUST be
replaced.
• Adjustable leg threads should be cleaned and lightly oiled.
• All locking claws should be cleaned, and the locking mechanism checked for operation.
• When storing your MAT, please ensure that all components are neatly stored and not left lying
around where they could be stood on or damaged.
• When transporting the MAT always tie the components down so that they do not move around and
get damaged.
• Should the tower be left unattended it should be tied to a suitable structure and on reuse ALWAYS
check that the tower is vertical and safe before ascending correct and complete structure.
• The MAT is not designed to be lifted or suspended as a complete structure.
• Always keep this instruction manual safe.
• Broken, damaged or incorrect components must never be used. The equipment shall be quarantined
and assessed for replacement repair or destruction.
WIND EFFECTS
• Beware of high, gusty, or moderate breeze conditions in exposed areas. It is recommended that in
wind speeds over a Moderate Breeze (see Beaufort Scale below) that work on the tower is stopped
and reassessed. If the wind becomes a Strong Breeze, (see Beaufort Scale below) the tower should
be tied to a rigid structure. If the wind is likely to reach Gale Force (see Beaufort Scale below) or
over, work should be stopped, and the tower should be dismantled.
• Beware of tunnelling effect caused by open ended buildings, uncladded buildings and building
corners.

Dismantling
The dismantling procedure should follow the assembly steps in reverse order, take particular
attention about the removal of guardrails and platforms.
You should ensure that you are standing in a safe position and always protected by guardrails
NEVER remove diagonal braces or stabilisers prematurely.
After removing the toe-boards the operator disengages the horizontal guardrail brace clamps
furthest from the trap door, horizontal guardrail braces are then removed with the operator
positioned through the trap door before descending to the lower level, from where the upper
platform and extensions/guardrail frames can be removed.
NOTES:
DO NOT OVER-REACH and NEVER DROP COMPONENTS when dismantling always lower
them to the ground.
STABILISERS
Attach one stabiliser to each corner of
tower at approx. 45 degrees. The
bottom clamp should be tted as low
as possible, refer to the diagram
opposite. Ensure that all four rubber
feet are in contact with the ground and
that the clamps are secured. Position
stabilisers as shown in the diagrams.
When using the S2 stabilisers, always
extend the telescopic legs to their
maximum position and lock into
position with the interlock clip.
When moving the tower lock each
telescopic leg just clear of the ground,
unlock castors ensuring area is rm
and clear of all obstructions both on
the ground and above.
After moving check all castors are
rmly on the ground and locked, and
that the tower is vertical. Re-position
stabilisers as above.
