Our client, a UK based multi-brand online retailer, required one of their most important lifts to be modernised. This business-critical lift was over 30 years old and works were needing to be completed before their Christmas peak period. The lift in question was a 7 floor, 5-tonne heavy passenger/goods lift.
The lift was designed in the late 70s with a Ward Leonard DC motor & and AC generator. The control panel was a relay-based VVF drive system manufactured by Thames Valley Control (TVCL).
