ProSilva 15-4ST

A 15-ton load softly –from soft terrain

ProSilva 15-4ST BogHopper track mounted forest machine is a uniquely light wanderer. Although machine weighs 35 000 kg when loaded, the contact pressure is very small. The rear suspension is supporting, also the suspension is made thinking about comfort and duration. The track plates are bent, so no tracks are left to the terrain.

Rear suspension

• a contact area with a 8 cm depression and 800 mm track plates: 7 m

• track frames are tilted along the terrain lengthwise and crosswise

• bent track plates

Suspension

• reduces vibration to the driver

• reduces stress to the machine body

• combined to an active swivel it transfers the pressure to the most supporting part of the terrain

Active swivel

• the position data of the machine from sensors

• swivel operation can be chosen by the driver

• in soft terrain the articulated joint is aimed to be held straight

• in uneven terrain cockpit movements can be balanced

ProSilva BogHopper is an unbelievable forest machine. Timber harvesting on soft terrains can be made around the year –powerfully and without damaging the nature.
