bystep instructions to ensure that your system is erected
with themaximum of ease and safety. Before assembly,
please read thesafety notes. Operatives must be qualified
or competent toerect the tower. If the scaffold is passed
on to another personthey should also receive these
instructions. Consult the PASMA Guide for full information
on the use of Mobile Towers.
Checklist
Inspect components prior to erection
Inspect tower prior to use
Tower upright
Castors locked and legs correctly adjusted
Braces & platform level
Stabilisers fitted as specified
Platforms located & windlocks on
Handrails in place
Toeboards located
Refer to this checklist before using each time.
Check that all components are on site and that they are
functioning correctly – (refer to check list and quantities).
Check that the ground is level and capable of
supporting the weight of the strucure.
During erection it is recommended that a temporary
guardrail brace be employed.
The safe working load is 220 kgs per platform uniformly
distributed, 500kg per tower structure.
This must not be exceeded.
The tower should always be climbed from the inside.
Do not use boxes or step ladders on the platform to
gain additional height.
Lifting of Equipment
Components should be firmly secured by a reliable

The device described in this manual is the Youngman MiniMax Mobile Aluminium Tower, a modular scaffolding system designed for safe and efficient work at height.

Function Description

The MiniMax Mobile Aluminium Tower provides a stable and secure working platform for various tasks requiring elevated access. It is designed for easy assembly and dismantling, with components that lock into place to ensure structural integrity. The system allows for different platform heights and configurations, including extensions for greater working heights. It emphasizes user safety through features like guardrails, stabilisers, and a trapdoor platform for internal climbing. The tower is intended for use by qualified and competent operatives who understand the assembly and safety guidelines.

Important Technical Specifications

• Platform Length: 1.83m
• Safe Working Load: 220 kgs per platform (uniformly distributed), 500kg per tower structure. This must not be exceeded.
• Maximum Free Standing Height (when moving): 3.7 metres (maximum free standing height 5.8 metres).
• Working Heights (m) and Platform Heights (m) for 1.83m platform length:
  • Internal/External Use:
    • Working Height: 2.8m, Platform Height: 0.9m
    • Working Height: 3.7m, Platform Height: 1.7m
    • Working Height: 5.7m, Platform Height: 3.7m
    • Working Height: 7.8m, Platform Height: 5.8m
• Component Weights (KG):
  • Folding Base Frame: 34 KG
  • Guardrail Pack: 16 KG
  • 2m Extension Pack: 44 KG
  • Small Stabiliser Pack: 12 KG
  • Medium Stabiliser Pack: 9 KG
• Stabiliser Requirements:
  • All 4 stabilisers must be fitted when specified.
  • When using the 1.7m tower externally, 4 small stabilisers must be fitted.
  • Small Stabilisers: Extend 2.9m from the base, with a 3.2m spread.
  • Medium Stabilisers: Extend 4.6m from the base, with a 4.2m spread.
  • Stabilisers should be attached at approximately 45 degrees to each corner of the tower, with the bottom clamp fitted as low as possible.
• Tie Frequency: Every 4m intervals vertically when ties are required. Ties should be rigid (e.g., solid tube and couplers) and attached to a solid structure.
• Wind Speed Guidelines:
  • Medium Breeze (Beaufort No. 4, 8-12 m.p.h / 4-6 m/sec): Raises dust and loose paper, twigs snap off.
  • Strong Breeze (Beaufort No. 6, 25-31 m.p.h / 11-14 m/sec): Large branches in motion, telegraph wires whistle. Cease working on the tower if wind speeds exceed 7.7 m/s (17 m.p.h.). Tie the tower to a rigid structure if wind becomes a strong breeze (expected to reach 11.3 m/s or 25 m.p.h.).
  • Gale Force (Beaufort No. 8, 39-46 m.p.h / 17-21 m/sec): Walking is difficult. Dismantle the tower if wind is likely to reach gale force (over 18 m/s or 40 m.p.h.).
• Maximum Horizontal Force: 20 kg (to prevent instability from power tools, etc.).

Usage Features

• Modular Design: The tower is built using various packs (Base Pack, Guardrail Pack, 2m Extension Pack, Stabiliser Packs) and individual components (Folding Base Frame, Trapdoor Platform, 8 Rung Frames, Diagonal Braces, Horizontal Braces, Toeboard Kit, Guardrail Frames, Stabilisers).
• Internal Climbing: The tower should always be climbed from the inside, using the trapdoor platform.
• Adjustable Legs/Castors: Features adjustable legs for levelling on uneven ground and lockable castors for mobility and stability. Castors should always face outwards.
• Windlocks: Platforms are secured with windlocks, which must be locked in position.
• Temporary Guardrails: During assembly, temporary guardrails are employed to ensure safety before permanent guardrails are in place.
• Bracing: Diagonal and horizontal braces are crucial for structural stability, following a zig-zag pattern.
• Toeboards: Toeboards are fitted to prevent objects from falling off the platform, ensuring no large gaps and allowing the trapdoor to open freely.
• Lifting Equipment: Components should be lifted within the tower's footprint, firmly secured by reliable lifting material (e.g., rope) and knots.
• Movement Guidelines:
  • Move the tower only by manual effort, from the base.
  • No person or materials should be on the tower during movement.
  • Exercise caution when moving over rough, uneven, or sloping ground.
  • Unlock and lock castors as needed.
  • Beware of live electrical apparatus, overhead wires, and moving machinery parts.
  • When moving, lock telescopic legs just clear of the ground, unlock castors, ensure the area is clear of obstructions, and re-position stabilisers after movement.
• Safety Precautions:
  • Do not use boxes or step ladders on the platform for additional height.
  • Do not abuse equipment; damaged or incorrect components must not be used.
  • The assembled tower is a working platform and should not be used as a means of access to other structures.
  • Beware of open-ended buildings that can cause funnelling effects of wind.
  • Ensure all components are on site and functioning correctly before assembly.
  • The ground must be level and capable of supporting the structure's weight.
  • During erection, a temporary guardrail brace is recommended.

Maintenance Features

• Regular Inspection: All components and their parts should be regularly inspected for damage, especially welds.
• Replacement of Parts: Lost or broken parts must be replaced.
• Tubing Integrity: Any tubing with an indentation greater than 5mm should not be used.
• Adjustable Leg Maintenance: Adjustable leg threads should be cleaned and lightly lubricated to ensure free running.
