Drum winches contain one drum with all the lift lines located on it. These lift lines then route up to a staggered multi-sheave head block across to individual loft blocks and then down to the pipe batten. Drum winches lift the entire load of the line set, no counterweight is needed. Drum winches can be controlled by a push button control systems, or the SHI-CHI control system.

The system is a perfect solution to where floor space is limited or structures cannot support horizontal loads. Line shaft winches have a single motor connected to a series of drums. The drums are connected via solid shafting and shaft couplers and supported with flange bearings on mounting plates. Line shaft winches are located centrally above the line set with the lift lines dropping straight down for the winch to the line set. Line shafts can also be located away from the line sets utilizing standard loft blocks to direct the lift line down to the line set. Line shaft winches lift the entire load of the lineset, no counterweight is required. Line shaft winches can be controlled by a push button control systems or the SHI-CHI control system.
