Winch

Winches face critical issues related to high loads during lifting and anchoring operations. Repeated stresses further compromise the operating system. Here is what SAI can offer to optimize operations:

  • Wheel or shaft units, ideal for motorization, offer radial load support and negative braking
  • Maximum control of rotation during lifting and anchoring operations, improving safety and efficiency
  • Double or variable fixed displacement controls to cover all functions required by the various types of winches.

COMPATIBLE PRODUCTS

TS8

GS

A fixed displacement motors series that can reach rotation speeds up to 3 times higher than traditional radial piston motors. The high ratio of maximum to minimum speed together with excellent efficiency and resistance to cavitation make this series ideal for high power density applications, where performance and reliability are the characteristics required of the circuit.

GM

Range of fixed displacement motors with established design obtained by continuous improvements from decades of field experience. High mechanical and volumetric efficiency and excellent resistance to cavitation make them the ideal product for all circuits where reliability, high performance and rotation control are required.

TD

Series of double displacement motors 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. It is possible to achieve minimum displacement 0 cc from any maximum displacement.
Maximum efficiency enables optimal engine performance even at 10 percent of maximum displacement.

BD

Double displacement motors available with a wide variety of displacement ratios (1:2; 1:3; 1:4 and possibility 1:0). The motors can handle power supplied in torque or speed depending on the application requirement. Displacement change can take place in motion and with hydraulic or electric drive, thus ensuring reliability and high performance of the entire hydraulic circuit.

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.
