Choose your configuration
All four models fold up, have a fixed boom and an electric wire hoist, and run on the vehicle’s 12V system. They differ in height and lifting capacity.
| Item no. | Model | Lifting capacity | Boom reach | Weight | Folded (W x H) |
|---|---|---|---|---|---|
| 4100 | Standard | 220 kg | 850 / 1,150 mm | 22 kg | 240 x 1,475 mm |
| 4110 | Low model, for vans with a low cargo area | 220 kg | 850 / 1,150 mm | 20 kg | 240 x 1,290 mm |
| 4200 | Reinforced | 400 kg | 850 / 1,150 mm | 29 kg | 240 x 1,475 mm |
| 4250 | High model, for extra lifting height | 80 kg | – | 25 kg | – |
What can it lift?
The crane is made for the equipment that goes in and out of the vehicle every working day. Fit the right lifting tool and it handles tasks like:
- Plate compactors, trench rammers and other smaller construction equipment
- 60-litre canisters, car batteries and steel drums
- Tools, machine parts and materials that are too heavy to lift by hand
Folds away when you don’t need it
Fold the crane up when the job is done. It takes up minimal space in the vehicle during transport and storage, so you keep your cargo space free.
One crane, many places: the universal baseplate system
You don’t need a crane for every vehicle. You only need a baseplate.
How it works:
- Install a baseplate wherever you want a lifting point: in a van, on a flatbed, on a trailer or in the workshop.
- Place the crane in the baseplate. It locks into place without tools.
- Lift the crane out when the job is done, and place it in a baseplate somewhere else.
Example: Install a baseplate in the van, one on the trailer and one in the workshop. One crane covers all three places. You move the crane, not the load.
Baseplates for every setup:
- Above the cargo floor: standard 50 x 40 cm or compact 40 x 40 cm
- Below the cargo floor: for a flat floor with no parts sticking up
- Vertical baseplate: for walls and the sides of machines
- Concrete block or crane trolley: a movable lifting point on site or in the workshop
- Custom baseplates: made to fit your specific vehicle or trailer
All Knap On cranes fit all Knap On baseplates.
Why choose it
- Lightest in the range: from 20 kg, so it uses very little of the vehicle’s payload
- Takes up little space: folds away when not in use
- Fewer heavy lifts: the crane takes the load, not your back
- No idling needed: the energy-efficient hoist runs on the 12V system without the engine running
