lifting equipment to install water heater - has frame adjusted by sliding screw operated trolley with pulley for positioning

摘要

The water heater mounting uses a lifting assembly with a horizontal screw at the top. The screw operates a trolley with a pulley to move the heater to and from the wall along a cable also passing through a fixed pulley. A winch operates the cable in each direction. Sleeves adjust the uprights towards or from the other uprights. The final positions are fixed by pins through holes in the uprights. The base is T-shaped to give stability for the structure.
