K55 SPH(Self-Propelled Howitzer)
This works as hydraulic driver installed on the turret and supplies hydraulic power to the elevation/balancing device for gun barrel and the slewing device and the automatic loader for a turret. Also, it plays a role in improving the driving performance of a vehicle and a smoother ride for the crew using Hydropneumatic Suspension Unit (HSU).

Elevation Balancing Cylinder
This device actuates the gun up and down with the controlled hydraulic oil supplied from the gun control system, and plays the role of protecting the system by absorbing shooting shocks during gun firing.
Elevation Limit Valve
This device limits the elevation so that the loading device does not collide with the floor of the equipment and is not damaged when operating above a certain elavation.
Ramming Driver
This device is used to automatically load bullets by moving the rolling pin assembly unit back and forth through the rectilinear and the reciprocation motion of the piston rod.
Swivel Valve Block
This device works as controlling the hydraulic operation direction when elevating the loading assembly unit.
Hydropneumatic Suspension Unit
This device minimizes vibration and impact transmitted from the ground when driving the vehicle using the attenuation characteristics of the damper and the nonlinear spring characteristics of nitrogen gas. This improves the driving performance of the all-terrain vehicle (ATV) and the ride comfort for the crew. In addition, it improves the performance of continuous fire and shooting accuracy by instantly stabilizing the vehicle's body when firing.
Hydraulic Power Pack
This device supplies hydraulic oil for control and operation of elevation, slewing, and loading systems by converting the power supplied from the power device into hydraulic power (pressure and flow).
Ramming Valve Block
This device works by controlling the hydraulic operation direction to move the rolling pin assembly unit for the loading assembly unit back and forth.
Manual Elevation Pump
This is a device to drive the elevation of the gun barrel through manpower and elevates the level of the gun barrel when the main operator for the elevation pump is broken.
Balancer Pressure Accumulator
This device compensates for the imbalnce moment that changes in relation to the elevation of the gun barrel using compressed nitrogen gas.
Main Pressure Accumulator
This device works by shortening the initial operation time of the hydraulic system and preventing pressure pulsation through storing the hydraulic oil supplied to the hydraulic pump of the hydraulic power pack after converting the power supplied from the power device into hydraulic power (pressure and flow).
