Electro Hydraulic Power Units

Twiflex has consolidated decades of development to produce a range of electro-hydraulic power units to meet most application requirements. Each power unit has been designed for reliability, high performance and low maintenance, and is supplied with a comprehensive easy-to-read installation, operation and maintenance manual. The Twiflex datasheets contain user guides giving a step-by-step selection process. Contact Twiflex application engineers to discuss your requirements in detail

LC - Electro Hydraulic Power Units

The "LC" range of stand alone power units is designed to operate the Twiflex range MR, MX, GMX, GMR and VCS spring applied hydraulically released brakes, providing a basic brake on/off control. There are various options available including "soft braking", a range of operating and motor voltages, and various add-on accessories including a terminal box.

The "soft braking" option is available as an additional manifold slice to facilitate a fast approach, soft braking system. This enables rapid closing of the pad/disc air gap followed by controlled application of braking force up to full torque. Refer to data sheet DS3001.

MP - Electro Hydraulic Power Units

The modular “MP” range of electro-hydraulic power packs has been designed to provide a completely flexible means of brake control in the most arduous operating environments.

The units are composed of one of three base modules, dictated by the size and number of calipers to be controlled, comprising motor, pump and reservoir.

The hydraulic circuit is then selected, based on the operation and control logic required by the application and may range from a simple ‘on/off’ function to full closed loop PLC control. Finally, auxiliary options are specified (for example, hand pump for manual caliper release; heater for low ambient temperatures; stainless steel components for marine environments, etc.).

The “MP” solution is especially useful when the application requires independent control of multiple brake circuits. Refer to data sheet DS3002 or contact Twiflex for more details.

Disc and Hub Assemblies

Twiflex produces a large range of standard discs and associated mounting hubs. These can be supplied pilot bored or fully machined to suit the particular mounting or shaft arrangement.

Special discs for specific applications may also be supplied on request – contact Twiflex to discuss your requirements.

Monitoring Units

Twiflex offers a wide range of monitoring options for both caliper and modular brake types. This includes a number of IP67-rated inductive and analogue proximity sensors for brake status or pad condition.

In addition, electro-mechanical and limit switches are available as single or multi-function units and may be supplied fully sealed, with positive action safety switches.

Monitoring units are used to indicate:

• Brake on or off, or the fully retracted condition reached
• Adjustment for pad wear required
• Pad replacement needed
• Any combination of the above
