Pulley perfection.

The DMM Gyro pulley range are  strong swing cheek pulleys with high efficiency roller bearings that can be used for all of your pulley requirements.

Precision engineered in our factory in Wales using hot forging and CNC techniques to create textile friendly, efficient and high performance pulleys.

Big bore axle technology provides increased resistance to side plate leverage.

The PM model features prusik minding side plates that mean it can be used in efficient progress capture hauling systems.

The Gyro Twin features prusik minding side plates and a load bearing becket and excels in mechanical advantage set ups.

Compatible with up to 13mm ropes.


Load bearing becket increases attachment options

The becket on the Gyro Twin is strength rated, and increases attachment options for greater versatility in rigging.

Prusik minding side plates allow progress capture when used in hauling systems

The Gyro Twin and PM's side plates prevents prusiks from entering the pulley body and jamming the sheave. This means they can be used in hauling systems with prusiks that capture rope progress for increased control over loads.

Compact design reduces system height

The Gyro's design minimises system height for efficient and easily managed rigging that is compatible with environments where space is at a premium.

Roller bearings for increased efficiency

Roller bearings are highly efficient, reducing friction and making movement and control of loads easier

Fairlead flares increase efficiency

The pulleys side plates are angled away from the sheave, giving a reduced bend radius and increasing efficiency if the ropes run over them.

Hot forged body reduces wear on ropes

The pulley body is hot forged to reduce the number of edges on the pulley. This reduces the amount of wear ropes experience when they run over the pulley body.
