Power transmission specialist Lovejoy LLC has further expanded its European presence and now produces torsional couplings from the LK series in its subsidiary company, R+L Hydraulics GmbH, headquartered in Germany.

The LK torsional couplings are for applications in mobile hydraulics with diesel, gasoline or natural gas engines which drive one or more flange-mounted hydraulic pumps. The LK torsional coupling is a stable, two-part coupling consisting of an element or flywheel adapter and a hub for connection to a shaft. The couplings are torsionally very stiff, enabling drives of hydraulic pumps and similar equipment with low mass or inertia to operate below critical speeds. Typical applications include excavators, vibratory rollers, loaders, cranes, passenger elevators, forklifts and tractors.

LK torsional couplings can be used with all engine-driven hydrostatic applications in the low to mid power range. They are maintenance-free and are low weight, with high torsional stiffness. Their performance spectrum includes all ranges from 125–6,000 Nm. The shape and length of the hubs are modifiable, different flange positions are possible. Various series are available for standardised SAE flywheels and non-standardised flywheels.
