A heavy-equipment field repair shelter was developed to satisfy the requirement of shelter for maintenance and repair of construction equipment up to Size 6 snow tractors in remote work centers at established polar stations. The shelter is constructed of steel arch ribs with a canvas cover. The basic shelter is 28 by 44 feet with a 12 by 28-foot shop at one end. An expansion unit can be added to the shop end to form a second repair stall. Outfitting for the shelter includes a 4-ton traveling hoist, an electrical harness, an overhead forced-air heater, shop equipment and tools.
