Mobile and Extendible Step Units

Ajax Mobile and Extendible Step Units have been designed to provide a safe working environment for workers who need to gain access to areas at various heights from the ground.

Each Step Unit has been designed for areas where floor space is considered to be at a premium and a fixed unit is not suitable.

The Step Units require minimum effort to operate and manoeuvre due to their have heavy duty locking wheels.

Each Unit also has a full safety cage as standard, which is attached to the Step Unit platform and provides an enclosed working area for maximum safety at height.

There are two designs to choose from depending on your access requirements; the counter-balance design and the outrigger design.

Construction

The Mobile Step Units have a robust yet lightweight construction, which are manufactured from mild steel and coated in a hot dipped galvanised. This method completely protects the Unit from any harsh environmental elements, making it suitable for both corrosive and chemical conditions.

The ladder and the safety cage are both fabricated from aluminium, which combined with the body of the Step Unit, gives excellent structural strength and manoeuvrability. The safety cage has a yellow powder coated finish (BS 08E51) for maximum visibility in low light conditions.

For high risk petrochemical environments, the Step Units can be supplied with comprehensive documentation to give evidence that all components and materials of each Unit fully complies with the latest ATEX Directives (94/9/EC).

Operation

The Mobile Step Units sit in a retracted position when not in us or while manoeuvring the Unit. Once the Unit is in front of its desired position, the height of the ladder can be adjusted using the mechanical winch slightly higher than the platform the operator wishes to access.

  • Minimum Access Height: 3500mm
  • Maximum Access Height: 4500mm

The Step Unit can then be moved into position and locked in place using the rubber locking wheels. For uneven or sloping surfaces, the Step Unit has adjustable stabilisers either side to cater for the gradient.

The adjustable ladder is then winched back down onto the platform ready to be used by the operator.

The safety rails and non-slip rungs of the access ladder will assist the operator in climbing the Step Unit safely.

Outrigger Vs Counter-Balance Design

Both Mobile Step Units provide the same safe access result, with only the design of the construction being the difference.

The Outrigger Mobile Step Unit has its feet positioned forwards, which can roll underneath a construction, vehicle or other object the operator is required to access.

The Counter-Balance Mobile Step Unit has its feet positioned backwards, with the addition of a triangle construction either side which acts as a counter-balance when an operator is in action. This design option is recommended when a construction, vehicle or other object the operator is required to access has a minimum floor clearance or no clearance at all.
