A perverse aspect of new technology is that it often complicates life, especially for ongoing maintenance. Fortunately, this is not the case with a hydraulic winch. In fact, there is almost no ongoing service needed. The only significant requirement is maintaining the cleanliness of the hydraulic oil.
Some of our winches have an independent hydraulic system, such as the H4A winch on Caterpillar G Series. This winch has its own hydraulic oil reservoir and filter. It is imperative to respect the replacement schedule for both fluid and filter on this winch. While the traditional PTO winch could run for years on the original oil (though not recommended), this practice won’t work on the H4A winch.
By contrast, some of our other hydraulic winches connect to the dozer auxiliary hydraulic circuit. Here, the oil change frequency is dictated by the dozer manufacturer. But it also must be respected faithfully.
