The ENDO EWF-50 is a zero-gravity spring balancer for any tool weighing 88-110 lb - for example welding guns, heavy nutrunner spindles, or fixtures - 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: 88-110 lb (40.0-50.0 kg)
• Factory-set load: 99.2 lb (45 kg)
• Cable travel: 4.9 ft (1.5 m)
• Wire rope: carbon steel, 0.19 in (4.76 mm)
• Unit weight: approx. 22.3 lb (10.1 kg)
• Fall-arrest device standard: if the spring ruptures, a safety pin stops the tool from falling anywhere in the cable travel
