Air Casters are also known as air bearings. It uses a continuous, regulated flow of air to create an air film between an inflated bearing element and the floor surface. The air casters are mounted to a rigid platform to provide load-carrying capability. The thin film of air created between the air casters and the floor surface allows the load to lift and float, virtually friction-free and omni-directional movement is achieved. Air casters present an alternative method for transporting heavy loads in manufacturing environments. Loads levitate upon compressed air plenums beneath air casters. The floor loading pressure is very low (on the order of 20 PSI), and causes no floor damage. Usually four or more air casters are positioned beneath the machine load to be moved. Sometimes the load is placed on an intermediate load base (thin pallet type structure) having air casters beneath it. These load bases are often custom manufactured for a particular product.
Air Chain Hoists feature compact & lightweight for portability, easy-to-adjust speed control for accurate load spotting, automatic brake is tail mounted for easy inspection & adjustment, upper & lower limit stops to prevent damage to the hoist and pull cord control & heavy-duty chain bucket. These hoists include multi-vane motor, which provides smooth operation & excellent control. Air hoists contain no complicated electronic controls and is less sensitive to adverse working conditions.
