A hydraulic power device for effecting operation of at least one load, the hydraulic power device including a motor having a predetermined motor speed rating and motor power rating, at least one pump operably coupled to the motor, the pump being configured to provide, to the at least one load, a predetermined hydraulic fluid flow at the predetermined motor speed rating, and a variable frequency drive connected to the motor, the variable frequency drive being configured to effect operation of the motor at a speed above the predetermined motor speed rating such that the at least one pump operates to provide an excess hydraulic fluid flow during operation of the motor substantially above the predetermined motor speed rating where the excess fluid flow is greater than the predetermined hydraulic fluid flow.

Hybrid electro-hydraulic power device

A through beam shear angle change, cutting blade deflection detector including a cutting member within a shear box of a recycling machine, a through beam sensor including an emitter disposed on the cutting member and a receiver disposed on the cutting member, the receiver being disposed relative to the emitter for receiving a signal emitted from the emitter, and a controller connected to at least the receiver, the controller being configured to determine an amount of cutting member deflection based on an output of the receiver.
