Truck Crane AK 42/4000

The power package on a 16 t or 18 t truck

The truck crane 42/4000 combines maximum ranges and payloads up to 4,000 kg on a compact ruck of 16 or 18 tonnes. With a winch of 2 tonnes, the AK 42/4000 is able to lift up heavy loads. However, the strengths of the crane are its ranges. Even under a load of 1,000 kg, the crane reaches a range of 22 meters. Therefore, the AK 42/4000 is good for the ambitious roofer, carpenter or solar and metal installation builders. Being a versatile machine, the crane can surely be converted to a lifting platform within a short time.  

Thanks to the stable mast package made of aluminium, a precise settling of the load is guaranteed all the time. Like all the other models the crane retracts or telescopes quickly and safe even under load. By the design-related incredibly low swivel radius, working is easily possible in streets even with running traffic.
