The Chester Zephyr Swivel Truck Low Headroom Trolley Hoist maintains the absolute minimum distance between the bottom of the runway beam and the hook saddle in the uppermost position. They are available in 1/4 through 6 ton capacities with either plain or hand geared trolleys. These hoists combine the advantages of the Chester swivel truck trolley design with compact construction without sacrificing any essentials of ruggedness. These units incorporate the same heavy duty steel components common to our Zephyr Hoist product line.
