The W12E winch is the largest PTO-driven towing winch on the general market, suitable for dozers up to 600HP. For massive jobs where compromise is not an option, the W12E is the preferred choice of towing winch for handling the toughest towing challlenges. Typically used in mining, conveyer relocation, railroad wreck recovery and large pipeline construction, the W12E winch can work under sustained load for long periods without adding excess heat to the dozer hydraulic system. The extreme duty drum seal option makes submerged operation feasible without risk of water and grit intrusion.
