ASYMMETRICAL FIBREGLASS LADDER FOR THE MAINTENANCE OF REFRIGERATION SYSTEMS

In the modern retail and wholesale trade individual

refrigeration units are often joined together in longer series

(‘multiplex’ systems), which makes access from the side

diffi cult. The multiplex systems are usually mounted on

walls, with the result that access from the back is not possible

either. Important parts, among others the refrigerant and

electricity, as well as pipes, cables, connections, valves, fi lters,

etc., are therefore often situated on the top of the systems, at

a height of 2–2.5 m. For maintenance and servicing purposes,

the installations on the top of the refrigeration systems have

to be regularly tested, cleaned and, if necessary, replaced.

This work has to be carried out while the systems are in

operation.
