Lectrotab Features

• Actuator has a completely non-metallic exterior for absolute resistance to corrosion. 
  
  

• Hardened steel, free wheeling ballscrew provides 1000+ pounds of force to the tab in both directions and eliminates electrical limit switches. 
  
  

• Available with 4 or 8 second stroke time in 12 or 24 VDC. Stroke length is 2 1/4 inches. 
  
  

• Lower scraper cleans the Ram when retracted but the water seal is located beyond where the fouled portion of the Ram can reach (US PAT.#5881666). 
  
  

• For retrofit, the Ram fits directly into the most popular tab bracket. 
  
  

• Screw hole pattern and wire exit position match the screw pattern and hydraulic connection of the most popular hydraulic type. Actuator wire may be routed neatly through the upper bracket or around the bracket. 
  
  

• Upper bracket can be positioned from vertical to horizontal. 

• Reversible D.C. motor is torque limited to protect the gearbox and current limited to protect the motor.
  
  
• Greased and sealed, 40:1 planetary gearbox vides smooth, quiet, high torque drive to the ballscrew. 
  
  
• Vent tube check valve allows air in, but not out, thus providing automatic internal pressurization each time the tab is retracted (US PAT. #5881666). 
  
  
• Controlled torque thrust bearing provides positive breaking against reverse free wheeling.
  
  
• 12-gage, 304 stainless steel, two-piece, integral hinge tabs have no welds, are straightforward to install and have no gaps in the hinge rotation are to become fouled.  Custom edge bends are available. Polished or powder coat optional.
  
  
• Tab bracket is secured with a flush head fastener pressed into the tab providing a smooth lower tab surface.
  
  
• Ram to bracket attachment is a shear pin.
