The ENDO EWF-30 is a zero-gravity spring balancer for any tool weighing 48-66 lb - for example heavy nutrunners, drilling units, or small 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: 48-66 lb (22.0-30.0 kg)
• Factory-set load: 57.3 lb (26 kg)
• Cable travel: 4.9 ft (1.5 m)
• Wire rope: carbon steel, 0.19 in (4.76 mm)
• Unit weight: approx. 17 lb (7.7 kg)
• Fall-arrest device standard: if the spring ruptures, a safety pin stops the tool from falling anywhere in the cable travel
