The Arcan 1, 500 lb. Engine Load Leveler has a 1, 500 lb. working load capacity accommodates most engines and can easily adapt to many engine hoist models to enhance their operation. The two support chains at each end support the load and help to transfer the weight safely while the one handed crank and asjustment rod allows you to easily reposition and redistribute the load. We put all of our lifting equipment through voluntary and rigorous third party safety testing, as outlined by the ASME PASE-2014 Safety Standard for Portable Automotive Service Equipment, to ensure that our products are among the safest on the market.
