You fabricate the girder and assemble the crane. We send a set whose hoist, end carriages, drives, panel and controls were engineered to work together — with the interface and load data you need to design the girder around them.
A crane kit is a matched set of the components a crane is built from — hoist unit, end carriages, travel drives, control panel and controls — engineered to work together and supplied to a crane builder who fabricates the girder and assembles the crane locally. It is not a complete crane.
Overview
A kit is configured per crane rather than picked from a shelf, and it normally contains:
Where the crane runs in a classified area, an ATEX version of the set is engineered to the site's own zone map and certified per project by a third-party notified body. See Explosion-protected cranes.
Kit scope
The split matters more than the parts list, so here it is plainly.
We send the components above, configured for the crane you described, with their technical data, the connection details at the girder interface, and the loads the crane will transfer.
You build and provide the main girder and its fabrication and paint, the runway and its conductor line, the structural design of the runway and building interface, the assembly of the crane, its installation, load test and commissioning.
Both halves have to be true for the crane to work, and the second half is where a kit either saves a builder time or costs them a rework. That is why the interface and load data leave here with the set rather than after it.
Responsibility
This is the question that decides how a builder files the job, and the category answers it badly, so we will answer it directly.
The party who assembles the crane and places it on the market is the manufacturer of that crane. If you build the girder, assemble our components onto it and hand the crane to your customer, that crane is yours: you carry out the risk assessment for the finished machine, you compile its technical file, you issue its declaration of conformity and you apply the CE marking.
What we supply does not change that, and it is not meant to. A kit is a mixture: some items in it are complete machines in their own right and carry their own conformity documentation, while others are supplied for incorporation into your machine and come with the documentation appropriate to that. Our job is to give you what your technical file needs from us, and to be exact about which item is which.
A supplier who tells you the kit is "CE certified" and leaves it there has told you nothing useful, and has left the ambiguity on your side of the table.
Design data
The one thing a builder cannot produce without us is what our components do to their steel.
With the kit we issue the wheel loads and the forces the end carriages transfer, the wheel spacing and the connection geometry at the girder, the hook approaches and headroom the arrangement produces, and the duty class the set is configured to. Those are the inputs to your girder section, your camber and your customer's runway check.
Getting them at configuration rather than at delivery is the difference between designing a girder once and designing it twice.
Technical data
Our wire rope hoists cover 250 kg to 160 tonnes as a family, in the BR23, BR30, BR33, BR36, BR46, BR58 and BR68 series, with the machine type set by the crane: double girder, underhung monorail or side-mounted. Machine-level duty is FEM 1Am (ISO M4) or FEM 2m (ISO M5) — the practical difference being 30% ED at 180 starts per hour against 40% ED at 240 starts per hour. At crane level the range runs FEM 1Bm to 5m (ISO M3 to M8), set per project.
Hoisting is stepless under inverter control, 2.3 to 8 m/min by series, reeving and duty class; trolley travel is stepless 4–16 m/min or fixed at 16 or 20 m/min. Supply is 380–415 V / 50 Hz, or 60 Hz for export, with IP54/IP55 protection and an ambient range of −10 to +50 °C.
The duty class is where most kit specifications go wrong, and it is worth settling before the capacity: a crane classed for the wrong duty is not a crane with the wrong hoist, it is a crane with the wrong life. The duty class guide sets out how it is determined.
Process
The components in a kit are the ones we build for our own cranes, in our own plant — the hoist unit, the steel fabrication, the end carriages and wheel groups. That matters to a builder for one practical reason: when something has to change late, it is our drawing and our line, not a conversation with somebody else's supplier.
It also means the parts stay available. Spares for the components you fit are the same items we hold for our own installed base, which is the question a builder's customer asks in year six rather than in week one. See crane spare parts.

FAQ
The kit is the hoist unit, end carriages with the girder connection, long-travel drives, the bridge panel with overload protection, the controls and the bridge electrification, plus the interface and load data. You fabricate and paint the girder, provide the runway and its conductor line, assemble the crane, and install, load-test and commission it.
You are. The party who assembles the crane and places it on the market is its manufacturer, which means the risk assessment, technical file, declaration of conformity and CE marking for the finished crane are yours. Our part is to supply components with the documentation your file needs from us, and to be precise about which item in the set carries which kind.
The wheel loads and forces the end carriages transfer, the wheel spacing and connection geometry at the girder, the hook approaches and headroom the arrangement produces, and the duty class the set is configured to. They are issued at configuration rather than at delivery, because they are inputs to your girder design and your customer's runway check.
The components in a kit are the ones we manufacture for our own cranes, so the spares your customer needs are the same items we hold for our own installed base. That is a different position from a kit assembled from parts bought in, where availability depends on somebody else's product cycle.
