The base structure includes a pair of outwardly extending legs which has primary wheels located adjacent the end thereof for transporting the hoist. A pair of auxiliary wheels are pivotally carried adjacent the primary wheels. The auxiliary wheels can be brought in contact with the surface lifting the primary wheels off the surface adding maneuverability to the hoist. A telescoping vertically adjustable safety standard engages the boom supporting the hoist for locking the boom in a fixed position.
