Component · Electrical
The controller is the part of a lift that ages fastest. Rails and structure last thirty years; control electronics rarely reach fifteen before parts get scarce.
Configurations
Configuration is decided by how many cars share the shaft group, not by building size alone.
What it does
On a modern lift this is a VVVF drive that ramps speed up and down rather than switching between two fixed speeds. That single difference is what people feel as a smooth stop.
Specification
An automatic rescue device brings the car to the nearest landing and opens the doors on power failure. On a residential building it is usually worth the addition.
When to replace
Controllers rarely fail outright. They become unsupportable, which is a slower and more expensive problem.
Once a board takes weeks to find, every future fault becomes a long outage regardless of who maintains the lift.
A two-speed drive switches rather than ramps. No amount of maintenance fixes that — it is a drive characteristic.
Ageing relays and contactors produce faults that come and go. Chasing them costs more over time than replacing the panel.
An old drive draws substantially more than a modern VVVF unit, which shortens the payback on replacement.
Ordering
Photographs of the nameplate save days. Most delays come from identifying the wrong variant, not from supply.
Common questions
Control panel price depends on configuration — simplex, duplex or group control — and on whether the drive is VVVF or a legacy two-speed unit being upgraded. Send the machine nameplate and the lift figures and we return a price against your actual controller, not a generic per-panel rate.
Often yes, if the machine and brake are sound. We inspect them first — fitting a new drive to a worn machine is not a saving.
Typically one to two weeks per lift including commissioning and drive tuning. In multi-lift buildings we phase it so a car stays available.
It is the core of it. Full modernization adds doors, cabin and fixtures, but the controller delivers most of the benefit.
Yes. Send the machine nameplate and photographs of the existing panel and we will confirm what fits.
Also supplied
Supplied for lifts we maintain and for lifts we do not.
VVVF drives and controllers. The part that most often decides whether an old lift is worth keeping.
OpenCar interiors in stainless, glass, stone and timber, with lighting and flooring.
OpenMachined T-section rails and brackets. Ride quality is mostly a rail alignment problem.
OpenGovernors, safety gear, buffers and interlocks — the parts that are never optional.
OpenSend photographs of the panel and the machine nameplate. We will tell you whether it is repairable or due for replacement.
