Features and Benefits

The device is designed to dismantle into a compact size making it easy to store and transport. It can also be manoeuvred or carried in its storage mode and has reflective livery so it can be seen at night.

The pivoting bearer beam with jacks at each end allows the lid to remain horizontal during the removal and replacement Extender Bearer Beam with Jacks process.

There are a variety of stock lifting keys available for use with most covers encountered in the UK. However should you have a specific key requirement then this can be easily manufactured and supplied.

The wheels are 260mm diameter with pneumatic tyres allowing the device to be travelled across a gravelled surface.

{note: the device is not designed to travel across rough terrain whilst fully loaded}

Operation Procedure

1 From storage mode, Wind the jack handle of the bearer beam anti clockwise (Figure 1). Pull the handle section back and lower it to the floor (Figure 2). Remove the bearer beam and place it over the lid.

3 The locating pin in the lower section should now be removed and the handle section guided through the gap in the lower section and locked into position by replacing the locating pin (Figure 3)
