 Time savings and ease of operation are big advantages.

Features

Built for Efficiency and Long Life
Time savings and ease of operation are the big advantages of the ASC Double-Arm Uncoiler. Its rugged design and efficient double-arm operation result in extremely quick coil changeovers. The integral hydraulic reservoir serves to increase cooling efficiency as well as reduce the floor space required for operation.

The system's modular design and steel alloy/cast components ensure strength and durability. The manifold mounted components and DIN solenoid connectors make for quick access and easy trouble shooting, while the low pressure hydraulic system maximizes equipment life.

Precise Coil Control
The Mandrel Drive Assembly in the powered Double-Arm Uncoiler runs in an oil bath, eliminating maintenance and prolonging gear life. Material payoff speeds of up to 300 feet (91 meters) per minute are achieved with precise coil control. Additionally, ASC Double-Arm Uncoilers feature wedge-type expansion for constant force throughout the expansion range. This wedge-type expansion utilizes three rugged mandrel segments pinned to the large diameter main mandrel shaft.

Drag brake, powered payoff or powered jog control options are available for all capacities of ASC Double-Arm Uncoilers. Material control is provided by a standard coil riding loop arm or by optional Smartloop or ultrasonic non-contacting loop systems.

Designed for Maximum Safety and Convenience
The Mandrel Expansion Circuit has been designed with a pilot-operated check valve to ensure operator safety and to prevent mandrel collapse in the event of power failure. ASC's Auto-expand feature is standard for maximum safety. Other safety/convenience features include:

Slew lockout circuit
Hydraulic expansion
Powered slew

The Overfeed/Underfeed feature provides additional flexibility in coil loading, while powered jog offers ease of threading and coil preparation.

The Best Factory Support System in the Business
