Bison 40t

COMEUP Bison 40t – Dual-Speed Hydraulic Recovery Winch. Bison and HV hydraulic recovery winches for recovery vehicles, heavy trucks and special-purpose vehicles, built for continuous duty.

Traditional hydraulic winches require a trade-off between line speed and pulling force. The Bison 40t Dual-Speed Hydraulic Recovery Winch eliminates that compromise by delivering both in a single winch. Operators can switch between High-Speed Mode for rapid cable retrieval and Low-Speed Mode for maximum pulling force, maximizing productivity without increasing hydraulic flow or system pressure.
  • Dual-Speed Operation
    High-Speed Mode for fast no-load recovery; Low-Speed High-Torque Mode for maximum pulling power.
  • 40,000 kg (88,184 lb) Pulling Capacity
    Powered by a 492 cm³/rev hydraulic motor for heavy-duty performance.
  • High-Precision Roller Bearings
    Fitted on drum and gear assemblies to reduce friction and extend service life.
  • Hardened 2-Stage Planetary Gear Train
    53.5:1 gear ratio provides optimal line speed and strength.
  • PTO-Driven System
    Driven by a PTO pump for variable recovery speeds and high work efficiency.
  • Air Clutch System
    Built-in air clutch for rapid and easy wire rope payout.
  • Patented Multi-Disc Brake (MDB)
    Ensures reliable, positive full-load holding safety.
  • Control & Safety Accessories
    Includes cable tensioner and two-way counterbalance valve.
  • Certified Compliance
    Meets SAE J706 and CE Machinery Directive 2006/42/EC.
