Features
Designed for reliable underwater use:
- 30-meter operational depth!
- Extremely durable construction including corrosion-resistant chain and housing and fully enclosed gear box
- Operates in a vertical or horizontal position
- Waterproof design protects all moving parts and bearings
- Corrosion-resistant offshore paint protection, classified C5-M (very high corrosivity – marine) per ISO 12944
Safe operation:
- Hydraulic motor generates no bubbles that interfere with spotting operations, unlike air hoists
- Manifold includes overload protection and quick-down valves acting as limit switches
- Durable, Grade 80 zinc-plated load chain with a 5:1 safety factor
- Accepts up to 50 bar (750 psi) pressure in return line, and provides fluid hammer protection
Easy to setup, handle and operate:
- Plug and play design ready to work right out of the box
- Quick disconnects on pendant hoses
- 100% progressive speed control delivers great spotting capabilities
- Pendant features large buttons for easy control with diving gloves
- Orbital hydraulic motor provides high torque and very precise positioning
