Incredible visibility and steering, unbeatable stability, excellent performance provided by the double-circuit hydraulics – bearing the environment in mind and with minimum surface pressure. The new PONSSE ScorpionKing offers improved productivity, cost-efficiency and comfort to the most challenging logging sites.

Focus on the driver

The eight-wheeled ScorpionKing offers the best possible setting for efficient and productive work. The unique new crane solution offers excellent visibility in all directions, enabling smooth and flexible working whatever the conditions. Good visibility to both sides of the cabin allows for efficient and unlimited operation – the trees to be felled, felling direction and position of piles can be selected keeping efficiency and eco-friendliness in mind.

As the cabin is located in the middle of the machine, the driver can easily see to the extremes of even dense thinning routes. Moreover, the driver is positioned in the middle of the cabin’s slewing ring: when the cabin turns, the driver does not feel like being on a carousel. This has a significant effect on comfort and well-being at work.

A driver’s machine

Cabin levelling keeps the driver stable, even on difficult terrain. The frame of the machine consists of three parts linked by rotating joints. The cabin is located in the middle frame, which is kept hydraulically balanced, while the front and rear frames tilt according to the terrain. As a result, the pivoting point is as low as possible, not only minimising tilting, but also helping to prevent the driver from swaying sideways.

Stable under all conditions

The incredible stability of the PONSSE ScorpionKing comes from its eight wheels and active stabilisation system. The patented stabilisation system is based on detecting the direction and position of the crane, and then pressing the rear frame in the direction of work. Pressing the rear wheels against the ground and the weight of the rear frame improve the machine’s stability significantly when working on one side – including when the machine is moving. In addition to cabin levelling, stability helps with providing ergonomic working conditions for the driver.
