1. A system, comprising:
an accumulator unit configured to store and release hydraulic fluid, wherein the accumulator unit comprises a high pressure accumulator and a low pressure accumulator separate from the high pressure accumulator;
a first variable displacement hydraulic rotational unit;
a first control valve comprising a plurality of ports coupled to the first variable displacement hydraulic rotational unit, the accumulator unit, and an energy input;
a second variable displacement hydraulic rotational unit;
a second control valve comprising a plurality of ports coupled to the second variable displacement hydraulic rotational unit, the accumulator unit, and the energy input;
a pressure valve coupled to the low pressure accumulator by a connection pipe; and
a hydraulic connector that couples the high pressure accumulator and the pressure valve to enable hydraulic fluid to be released if peak loads occur.
