Twin Disc Inc. has introduced the RO 314/311 power take-off (PTO). The RO 314/311 is a “Remote Over Center” PTO that can be engaged and disengaged remotely via a control valve and/or electronic control when machinery configurations or location hinder easy access to activation. Hydraulic or pneumatic actuation is achieved through ports, making access to the fittings uncomplicated and straight-forward, the company said.
According to Twin Disc, hydraulic or pneumatic pressure is required only to engage or disengage the PTO; the fluid or air supply can be shut off when not needed.
The RO 314/311 uses a patent-pending design to remotely engage the over-center mechanism in the company’s proven SP 314/311 PTO and is complementary to the previously released RO 114/RO214.
The RO 314/311 is dimensionally similar to the company’s current mechanical SP 314/311 PTO. It continues to utilize three 14-in. (355-mm) friction plates in the 314 and three 1-in. (25-mm) plates in the 311. Existing SPs may be field converted to an RO using kits available from Twin Disc.
The design of the PTO allows for side load and inline applications. External cooling, filtration or a rotary union are not needed, the company said.
The RO 314/311 targets a wide range of industrial applications including oil and gas production. The units are installed by OEMs and in custom settings.
Headquartered in Racine, Wisconsin, USA, Twin Disc designs and manufactures heavy-duty industrial equipment. Its portfolio includes power-shift transmissions, mechanical and hydraulic power take-offs, gearboxes, torque converters, pump drives, air clutches, electronic shift controls and universal control drives.
