The 3 Section Wind-Up Stand with Auto Self-Lock is the perfect combination of strength and safety. The crank handle raises a maximum load of 66.10 lb to a height of 149.7" in 1.73" increments per single clockwise revolution and self-locks for safety. The stand is large enough to support a skid-proof step that allows access to its upper section, while the universal head offers 3 mounting options. The steel wind-up stand features a leveling leg for uneven terrain and a 2 riser, 3 section design.
