A Hydraulic Power Pack like the ones from https://www.hydraproducts.co.uk/Hydraulic-Power-Units/Standard-Power-Units can help you to power a number of equipment types. Hydraulic units use fluid to build up pressure in a container that then allows for a force to be pushed onto the equipment piece to make it move.
If you are interested in finding out how a hydraulic power pack works here is a quick guide for you.
The fluid used in the hydraulic system is kept in a reservoir container, valves allow for the water flow to be started and stopped. This fluid is pumped using the motor pumps and pressure is exerted on the fluid. As the fluid is in a contained unit the forces hit the edges of the container which build up the power of the force. The accumulators help to maintain the fluid pressure.
The force that is created inside the hydraulic unit then creates a mechanical force. This force is collected by the actuators. The force is directed to the machinery or mechanical element that is attached to the hydraulic pump or power pack. Now the mechanical item will move in whatever way is intended. This could be a brake being applied to a vehicle, mechanical arms moving to lift items or large cranes moving extremely heavy loads from one place to another.
