On all three models, the boom is raised with a manual hydraulic hand pump. They differ in lifting method, boom extension and capacity.
| Item no. | Lifting capacity | Hoist | Boom extension | Boom reach | Power | Weight | Folded (W x H) |
|---|---|---|---|---|---|---|---|
| 4300 | 400 kg | Fixed chain | Manual | 1,200 mm | None | 40 kg | 510 x 1,140 mm |
| 4400 | 350 kg | Electric wire hoist, 14 m | Manual | 1,200 mm | 12V, max 57A | 42 kg | 510 x 1,095 mm |
| 4500 | 350 kg | Electric wire hoist, 14 m | Electric | 1,010–1,550 mm | 12V, max 57A | 46 kg | 510 x 1,095 mm |
What can it lift?
The crane is made for heavy equipment that has to go in and out of the vehicle every day. Fit the right lifting tool and it handles tasks like:
- Plate compactors and other construction equipment
- 60-litre canisters, car batteries and steel drums
- Quarter and half pallets on and off flatbeds and trailers
- Tools, machine parts and materials that are too heavy to lift by hand
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 the same baseplate.
Why choose it
- Works without power: item no. 4300 runs on the hand pump alone, with no wiring and no drain on the battery
- Up to 400 kg: the highest lifting capacity in the Knap On range
- Fewer heavy lifts: the crane takes the load, not your back
- One crane, several vehicles: move it between baseplates in vans, flatbeds and trailers
