The NAT is a spring applied, electrohydraulic thruster released, industrial drum brake.

This thruster drum brake fits brake drums with dimensions in imperial units (inches) and is designed according to steel mill standards (AISE Standard No. 11). Because of this, the NAT brake is an ideal “bolt-in” replacement for many older steel mill brakes. Braking torque is adjustable, enabling fine tuning when upgrading an existing braking system.

Hindon provides full support for NAT brakes including repair services and full engineering, technical, and application support.
