The ENDO EWF-70 is a zero-gravity spring balancer for any tool weighing 132-154 lb - for example large welding guns or heavy 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: 132-154 lb (60.0-70.0 kg)
• Factory-set load: 143.3 lb (65 kg)
• Cable travel: 4.9 ft (1.5 m)
• Wire rope: carbon steel, 0.19 in (4.76 mm)
• Unit weight: approx. 25.1 lb (11.4 kg)
• Fall-arrest device standard: if the spring ruptures, a safety pin stops the tool from falling anywhere in the cable travel
