Recommendations
The lift control
panel had been submersed in sewage and the microprocessor printed
circuit boards exposed to the necessary hygiene cleaning chemicals.
Therefore, given the potential for an adverse effect on the safe
operation of the lift and continued component failure we recommended
complete replacement of the control panel. Furthermore the lift
trailing cables were connected directly between the control panel
and lift car. Consequently the trailing cables displayed evident
of contamination and would require replacement.
Our recommendations
also included through cleansing of the lift shaft pit area and
lift shaft. All the evident corrosion to lift guide rails, lift
shaft steelwork and hydraulic ram support was to be cleaned,
examined and re-painted. The hoisting ropes and rope termination
hitches within the lift shaft pit were corroded. Therefore we
recommended replacement of the hoisting ropes and hitches. Upon
completion of the all the remedial repairs the lift was subject
of a full series of commissioning/safety tests prior to restoration
of normal operation.
The aforementioned
recommendations of J Bashford and Associates resulted in an early
restoration of the lift service. Our knowledge and |
experience providing
a safe and reliable long-term lift operation at the saving of
several thousand pounds to the owners

Future operation
The existing lift
control panel cabinet was a floor mounted design. Therefore given
the layout of the communal sewage/drainage system and the juxtpositioning
of the inspection manhole within the floor of the lift plant
room, there was potential for a re-occurrence of this incident
with similar cause and effect. Our recommendations for the future
operation of the lift included the provision of a wall mounted
replacement control panel complete with a sealed hinged access
door and raising the hydraulic drive unit onto a suitable frame/stool.
The key here is, although you think you are getting the advice
of experts, check how independent it is. |
