Description
The UTS 1450/850 Ladder AGR tower is manufactured to BSEN1004-1:2020 CLASS 3 8/8 XXXD H2 and TARGET
MARKED. The TARGET MARK is a recognised symbol that reassures the user that the product is certied to BSI
stated standards.
The UTS 1450/850 Ladder AGR tower is a lightweight aluminium industrial tower designed for use in a variety of
commercial and domestic environments. It gives a safe and secure and robust work area at a range of heights
indoors and outdoors to enable maintenance, installation work and short term access, ensuring that working at
height is as safe as possible.
• Instructions for erection and use to be followed carefully.
• The UTS 1450/850 Ladder AGR has a maximum working platform height of 8.2 meters outdoors and 8.2
meters indoors.
• This is a Load Class 3 MAT, therefore maximum permissible load on the UTS 1450/850 Ladder AGR tower is
950kgs and evenly distributed on each platform is 275kgs. This must not be exceeded over the working height
platforms, not including rest platforms.
• Maximum of 1 working platform per tower.
• Maximum of 2 people per working platform.
• Damaged or incorrect components shall not be used.
Risk analysis
Proper risk analysis of our towers reveals that all components are integral to the safety of the tower once assembled,
and while assembling is the greatest period of risk. If the user follows the instructions set out in this manual it will
contribute to the reduction of risk of injury, this along with the PASMA training recommended in the manual should be
enough to signicantly reduce the risk possibility down to improbable if not impossible.
The components have been designed in such a way that they can be assembled in an order that allows for minimal
risk to occur, such as making locking parts easy to lock but harder to unlock to ensure easy assembly but prevent
accidental removal during use, and colour coding parts that are harder to distinguish between. Instructions in the
manual and training courses are very clear about how to access the tower and the correct method is displayed on
the tower as a reminder, but ensuring all components and materials are of the highest standard, means we can be
condent that even if misuse was to occur, we can be condent that the components would be able to still prevent
injury.
It is important to limit the risk of all tasks especially when working at height. It is the user’s responsibility to complete
a risk assessment then use that to reduce the risk associated with the task (a blank one can be found at the back of
this manual). Once the full risk assessment is completed and all hazards have been identied and controlled it is
down to the user to decide if there is still too much risk in which case do not erect or use tower and look for
alternative access arrangements.
Safety Notes
ERECTION & DISMANTLING - THE AGR (Advanced Guardrail System) 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 Ladder AGR tower is the AGR Method.
This method ensures the operators erecting the tower position themselves on a guarded platform to add or remove
advanced guardrails for the next level up.
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 7)
• Do not use boxes, ladders, or other devices on the platform to gain additional height.

• 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.
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.

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 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.
When using tower near a wall or in a
corner, the stabiliser layout needs to
adjusted to accommodate.
As shown in the diagram if against a
wall 2 stabilisers should be made
parallel to the wall and the others
should remain at 45°.
If being used in a corner, the closed
corner stabiliser can be removed and
the 2 near walls should be made
parallel with the open corner stabiliser
remaining at 45°.
