Spare Parts / Equipment Supply.
Marine crane spare parts, hydraulic motors and pumps, valves, electrical components, joysticks, wire ropes, seals and overhaul kits.

Spare parts supply is a department of its own at CranesTech because a repair is only as fast as the part.
Spare parts supply is a department of its own at CranesTech because a repair is only as fast as the part. We keep common wear parts, seals and overhaul kits for the crane makes we service, and we source pumps, motors, valves, electrical components and wire ropes from the manufacturers and from the market.
Every request is checked against the crane's type plate and the maker's parts list before an offer is made, so the part that arrives is the part that fits. Where the original is no longer made, we offer a tested alternative and say clearly what it is.
The product catalogue on this site lists the hydraulic, mechanical and electrical families we supply, from Bosch Rexroth and Danfoss piston pumps to Hägglunds motors, Spohn+Burkhardt joysticks and rotation-resistant hoist ropes.

What to send us
- Crane type plate: maker, model, serial number
- Part number or a photo of the part and its plate
- Quantity and whether the vessel needs it on board or at the agent
- Delivery port and the date the vessel arrives

- 04Hoist rope renewal: rotation-resistant rope supplied with certificate and reeved by our team.
Asked before the first visit.
Do you supply original parts or alternatives?
Both. The offer states which it is. Original parts are sourced from the maker or its distributors; alternatives are parts we have fitted and tested on the same crane type.
How quickly can a part be delivered to a vessel?
Stock items leave the same day. Items on order depend on the manufacturer; we quote the lead time with the price and can arrange delivery to the agent at the port of call.
Can you identify a part from a photo?
Usually yes, if the type plate of the crane or component is in the photo. Dimensions help when the plate is missing.
