The ENDO EWF-40 is a zero-gravity spring balancer for any tool weighing 66-88 lb - for example multi-spindle nutrunners or welding guns - and works equally with any other tool or device in that weight range. It holds the load weightless at any point in its 4.9 ft of cable travel.

Specifications:

• Capacity: 66-88 lb (30.0-40.0 kg)
• Factory-set load: 77.2 lb (35 kg)
• Cable travel: 4.9 ft (1.5 m)
• Wire rope: carbon steel, 0.19 in (4.76 mm)
• Unit weight: approx. 21.4 lb (9.7 kg)
• Fall-arrest device standard: if the spring ruptures, a safety pin stops the tool from falling anywhere in the cable travel
