Functions of Power Pack
Produce hydraulic power and pneumatic power.
Power is transmitted to different components of CTU to perform their respective functions thru a system of hosed and valves etc.
Almost 90% working of CTU is based on hadraulic power.
Remaining 10% functions are performed using pneumatic power.

Structure and Working of Power Pack
Composed of diesel engine.
Converts chemical energy into mechanical energy of flywheel.
Engine may be Detroit or Caterpillar

Hydraulic System
Hydraulic system is the core of Power Pack.
Function of hydraulic system is to produce and distribute hydraulic power to different CTU components.
Mechanical energy of engine flywheel is then provided to 04 hydraulic pumps thru gear box.
Hydraulic pumps then convert this mechanical energy into hydraulic energy.
Hydraulic energy is then transmitted to different CTU components thru hoses and valves to perform their function.

Components of Hydraulic System
Hydraulic fluid
Hydraulic fludi reservoir
Filters and strainers
Hydraulic pumps
Accumulator
Heat exchanger
Hydraulic circuits

Uses of Hydraulic Power
Hydraulic power is used to perform
CT Reel functions
CT Injector functions
BOP functions

Pneumatic System
Pneumatic system refers to production and distribution of high pressure air.
Pressurized air is used to perform
Engine emergency kill
Throttle function
Fuel combustion
Stripper function
