Chain Lift Design The FISHER® chain lift design offers a wide range of performance and reliability advantages over a direct lift system. Clean Scraping: The chain lift design allows the blade to continuously “float” while plowing, enabling it to freely follow the contours of the plowing surface for a cleaner scrape. Higher Stacking: With a chain lift you can stack snow higher because the plow’s movement is not restricted by the length of the ram stroke like on cylinder lift systems. Reliability: With the simple mechanical chain lift design, there are fewer hydraulic and electrical components to worry about, so you can count on long life dependability. Easy Recovery: In the rare event of a hydraulic failure, you can push the snow plow up into a snowbank and “short chain” it to the specially designed bracket for safe transport back to the shop.
