Working in extreme forest environments presents many challenges such as uneven ground and adverse weather conditions: operating machines must be able to cope with them, without compromising safety and efficiency. SAI designs solutions that meet these requirements:

  • Proportional variable displacement motors with minimum to maximum ratios up to 10:1 that offer high torque without the need for gearboxes or clutches
  • Transmission configurable with motor on axle or gear motor on wheels for greater flexibility
  • Possibility of equipping wheel assemblies with positive and negative brakes

COMPATIBLE PRODUCTS

TS8W

Fixed displacement seven-piston wheel motor integrated with a planetary gearbox having a 6:1 reduction ratio, also available with negative brake version (TS8WF).

K4

Fixed displacement motor with integrated planetary gearbox having 7:1 or 5:1 reduction ratio, also available with negative disc brake version (BVFK3). The BVK series is also available with different hub types (31A, 31B, 31D).

K4D

Double displacement motor with integrated planetary gearbox with 7:1 or 5:1 reduction ratio, also available with negative disc brake version (BVFK3). The BVK series is also available with different hub types (31A, 31B, 31D).

TS5V

Variable displacement motor with integrated planetary gearbox having 5,6:1 reduction ratio, also available with positive brake (DYN). Hub (41A) option is also available.

K4V

Variable displacement motor with integrated planetary gearbox with 7:1 or 5:1 reduction ratio, also available with negative disc brake (BVFK4). The BVK series is also available with different hub types (31A, 31B, 31D).

TV

Series of variable displacement engines with extreme specific power.
High sustainable pressure and flow rate make T motors ideal in the most severe and demanding applications.
TV-TD motors allow continuous displacement variation. Minimum displacement 0 cc can be achieved from any maximum displacement.
Maximum efficiency enables optimal engine performance even at 10 percent of maximum displacement.
