General information

We have manufactured a self-supportive crane frame with its own power source and a knucle-boom crane. It can be towed on a small size trailer or a small truck as cargo. It can lift it self off of the vehicle and be used as a stationary  construction crane. Furthermore, it can be moved on road, and into position by a self-propelled radio controlled trailer that we also manufactured. The crane frame is powered by a hybrid power pack. It can be driven on diesel fuel an/or electric power. In this way, the crane can work on site without noise and emissions.

The crane has three joints, which makes it extremely flexible. It is radio controlled and has a horisontal outreach of 9,4 m, where it can lift 300 kg.

The crane frame has 100% lifting capacity in a 360° sector without counterweights, which is remarkable!

The hydraulic power pack has an extra outlet for hydraulic tools. For example, it can run a hydraulic generator of until 7 kW and provde electricity to your construction site. It can also run a core drilling machine, bilge pumps, hydraulic high pressure washers, hydraulic wiches, etc. For maximum flexibilty, the crane can lift its own power pack off of the crane frame and over on a pickup truck etc, for use as a separate power pack. In this case, the crane is connected to a separate hydraulic outlet on the trailer, who has its own power pack. 

The trailer is a radio-controlled diesel driven three-way tipper. It can move the cunstruction crane by it self, be used as a load carrier or as an ordinary trailer. For maximum safety, the trailer has automatic rear stabilizers who adapt to the terrain when tipping. Furthermore, it has powerful woking ligts to the front and rear, 360° warninglights and movement activated sound warning. Everyhing is conveniently operated on the radio control panel, as well as start and stop of the power pack that runs it.

The propulsion system consists of two hydraulic motors with robust drive wheels. When activated, they are pushed down between the trailers wheels with hydraulic force. This provides a powerful four-wheel drive. The trailer can easily manouver with full load, even in rough terrain.
