On enquiry
Already have a cart? Upgrade it.
Many plants run sound cart structures with worn-out lead-acid batteries, trailing cables and pendants. We keep the steel and the wheels and replace the power and the controls.
What we replace
New power and control, same cart
- Lithium pack and BMS in place of lead-acid: no acid topping, faster charging, longer life
- Industrial radio remote in place of the pendant: the operator stands clear of the load
- Modern motor drive with soft start and stop: less shock to the load and the gearbox
- Laser anti-collision, E-stops, beacon and horn
- Optional: station auto-stop and an interlock with the crane above
What we keep
The parts that still have life
- Platform and structure, after inspection
- Rail wheels and axles, if wear is within limits
- Gearboxes, if they pass inspection; otherwise replaced
- Existing rails, after a straightness and level check

How a retrofit runs
Survey first, then a fixed scope
Survey
We inspect the cart, rails and route, and log a day's trips.
Proposal
A fixed scope: what is replaced, what is kept, and the downtime needed.
Shutdown work
Fitting planned around your maintenance shutdown.
Trial and handover
Load trial on site, operators trained, documents handed over.
| What we need to know | Why |
|---|---|
| Cart capacity and self-weight | To size the drive and the battery |
| Present power supply | Battery, trailing cable, cable drum or bus bar |
| Route length and trips per shift | To size the battery and plan charging |
| Motor and gearbox nameplates | To decide what can be kept |
| Photos of the cart and rails | For a first view before we visit |
Send us photos of your cart
A few photos and the nameplates are enough for a first opinion.
