Minimal Pit Depth Required
Many elevators require very deep pits and holes bored several meters into the ground. Powerglide Elevators have a pit depth requirement of only 300mm, and unless your lift is travelling more than 3.6m there is no requirement for any hole.
Benefits:
Can be used for builds near the water-table as there is no risk of water entering the lift shaft
Suitable for projects on very hard ground
Ideal for retrofitting into an existing building as minimal digging is required
