1452 Autodrape®, 2902 Silver Service®, 6502 Hercules® Line Shaft Lift Machines

Models 1452, 2902 and 6502 are designed for mounting directly to a facility's structural steel by means of compression clamps. The machine's output shaft is coupled directly to a solid steel shaft (Model ST-1) and is supported by flange bearings (Model BBA-3) along its length from a common structural steel member. Powder coated steel spools or Yo-Yo drums are fixed to the steel shaft and the individual lift lines are then attached to these spools or drums. These units are equipped with motors which provide instantaneous stop, start, and reverse action from any point of travel. Integral rotary limit switches provide user definable pre-sets for the "Full Raise" and "Full Lower" positions. The exact size of the supporting stuctural member must be supplied at time of order.

Model designation is for machine only.  Line shaft, couplings, bearing brackets and spools available separately.  Two shaft sizes (1" and 1-3/8") are available with the size determined by the load and span of the system. 

Model differences are based on horsepower of motor used.  Configuration and size is same for all models.

Standard unit is equipped with:

  • Rotary Limit Switches for full open and full closed positions
  • Full Voltage Control - motor voltage and amperage flows through remote switch (low voltage MCSA+LVCS is available as an option)
  • Remote Control Station only one (1) may be used (with MCSA+LVCS option, unlimited number of remote stations may be used)
  • Direct drive, no belts, pulleys or chains on power side of machine
  • Channel Mounting Base - 14" x 14"
  • Connects to 120 volt power supply
  • ETL Listing on the entire machine, not just the control box
  • Approximate shipping weight 90 pounds
