CK20-1 Komatsu CK20-1 Specifications & Technical Data (2005—2012)

PPC servo-controls

The PPC servo-controls make the CK20/30 easy to use. Natural movements and maximum precision guarantee unique efficiency and greatly contribute to reduce operator fatigue. The right joystick controls the movements of the arm and of the bucket; the left one controls the translation.

Automatic Power Control device (APC)

Thanks to the APC device, the operator can always use the engine’s full capacity, with no waste of power or overloads. It gives priority to the work equipment, makes the most of the residual power by sending it to the travelling motors, and prevents engine shutdown – even during the toughest operations.

Spacious cab

A spacious cab, with a wide entrance and comfortable seat, provides a level of comfort that is unmatched in this class of machines. Ergonomic controls and the excellent 360° visibility make the operator’s work much easier and safer on any job site. On request, the CK20/30 can be equipped with an exclusive front door that fits under the roof, and with side windows and heating or air conditioning for maximum comfort in all seasons.

Accelerator pedal

For an optimised engine usage, lower fuel consumption and improved acoustic comfort the operator can also adjust engine rpm with the accelerator pedal without removing the hand from the joystick.

Safety sensors

In case of unauthorised manoeuvres, a sophisticated system of sensors located on the safety bars and on the seat prevents all machine movements by automatically braking on the transmission and inhibiting the PPC controls. The ROPS-FOPS cab, the excellent dynamic stability of the machine and a 360° visibility combine to give the operator complete confidence in any situation.

Brakes

The service and parking brakes are incorporated into the translation motors. They are hydraulic negative action brakes and can be set “on” or “off” with a button located on the board to the left of the operator. The brakes are always “on” when the engine is not running.

Controls

Proportional servo-controls (PPC). The left lever controls the machine movements, the right one controls the working equipment. The pedal controls the auxiliary circuit for attachments. A safety system neutralises all operations when the safety bars are risen or the operator is not seated.

LCD panel

The LCD panel on the safety bar allows to closely monitor all the machine’s main functions: from fuel level to water temperature, air filter condition, engine oil pressure and more.

Easy access to inspection points

Routine maintenance and check-ups can be performed by simply opening a rear bonnet that also allows the user to clean the inclinable radiators. For extra servicing, the tilting cab offers complete access to the transmission and to the main components of the hydraulic system. Special self-lubricating bushings increase the greasing intervals for all pins up to 250 hours.

Undercarriage

The tracks ensure exceptional stability and traction on all types of soil including mud and snow, minimizing weather-related downtime. The wide base gives excellent stability to the machine, greatly reducing vibrations and increasing operator comfort. The hard steel ensures high resistance to all parts that are most subject to wear, such as gears, rollers and idlers. At the same time, a bigger section and multiple rubber covered steel reinforcements give the shoes a longer duration.
