The Arcan ALSS15 1500 lbs. Under hoist Support Stand has a supporting capacity of 1500 pounds. The slender design provides lightweight and easy handling in close quarters. The 12" base gives the stand better overall stability while the threaded spin handle provides a self-locking feature to prevent the stand from lowering without assist. A bearing mounted spin handle allows for smooth and easy turning when adjusting the height under 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.
