Mobile access towers are a type of lightweight scaffolding system. Usually made from aluminium, they can be easily moved from one place to another. We predominately use HAKI tower systems, where we SUPPLY, ERECT, HANDOVER the Tower to allow all necessary site members to access the roof.
HAKI TOWER
The HAKI Stair Tower is a versatile staircase system that can be set up for ascending in either a clockwise or counter-clockwise direction. It can accommodate single or double stair flights and allows for entrances and exits in all directions. The system features large landing areas and beam spacings of 2.0m, 1.5m, and 1.0m.
The HAKI Public Access Stair is a robust, safe, and all-inclusive solution for temporary public stairs. It’s perfect for public use and contractor stairs on railway and infrastructure projects, as well as for emergency exits.
HAKI Suspended Stair Towers use the same components as a traditional stair erected from the ground, but with the addition of suspension devices or supporting scaffold above.
The Compact Stair Tower is ideal for locations where space is at a premium, with a footprint of 2.5m x 1.25m.
Construction Site Stairways can handle a variety of pitch angles and are available in both steel and aluminium. They come in six independent sizes: 3, 6, 9, 12, 15, and 18 steps.
Inspection Requirements
Regular inspections are crucial to maintain the safety and integrity of HAKI stair towers:
Daily Checks:
Inspect the tower for any signs of wear or damage before use each day.
Weekly Inspections:
Conduct a more thorough inspection weekly, checking all bolts, clamps, and structural components.
Post-Weather Event Inspections:
Inspect the tower after severe weather conditions to ensure stability and safety.
