MANEUVERABILITY CHARACTERISTICS OF CABLE SKIDDER     pdf     HR     EN 259
Summary
Maneuverability of specialized forestry vehicles is defined by their ability to overcome terrain unevenness during which interaction between vehicle and terrain geometry occurs. Maneuverability, as a segment of vehicle mobility, is defined by: 1) obstacle crossing, 2) vehicle controllability and 3) ride comfort.
Vehicle specifications are determined during design and construction (dimensions, steering and locomotion systems, mass and its distribution on axles etc.) and together affect the level of vehicle maneuverability. Independently of vehicle purpose, many maneuverability parameters (directly connected to operational use) including approach, departure and ramp (break-over) angles as well as clearance radii are known, but their calculation for varying types of vehicles (different construction, purposes etc.) is still vague.
On the example of wheeled cable skidder, this paper deals with approach, ramp (break-over) and departure angles, longitudinal and transversal clearance radii as significant parameters for skidder mobility and maneuverability on uneven forest stands. Considering specific wheeled cable skidder design and construction together with constant relation of dimension characteristics regardless of different manufacturers, expressions for approach, ramp break-over and departure angles, longitudinal and transversal clearance radii are derived.

Key words: skidder; approach angle; ramp (break-over) angle; departure angle; longitudinal clearance radius; transversal clearance radius
