The two new machines provide significant productivity and versatility advantages compared with conventional rubber-tyre skidsteers, particularly in soft underfoot conditions.
"These new crawler skidsteers combine the compactness and versatility of our rubber-tyre skidsteers with the exceptional weight distribution and traction of crawler tracks," said Carl Grundy, Komatsu Australia’s National Sales Manager Utility.
The CK25-1 has a rated operating capacity of 1030 kg and is powered by a Komatsu 4D98E-2NFE diesel rated at 51.8 kW, while the CK35-1 has a capacity of 1470 kg, and is powered by the same Komatsu engine, rated at 62 kW.
In addition, they feature a unique Komatsu vertical-lift design that keeps the bucket reach constant during the lift cycle, allowing higher tipping loads than for conventional machines.
This also makes them well suited for pallet-loading operations, as fork attachments stay parallel to the ground throughout the lift cycle.
"While these two new machines share significant parts commonality with our rubber-tyred skidsteers, the crawler undercarriage section has been designed from the ground up.
"It’s not simply an adaptation of our rubber-tyre drivetrain, so there are no compromises – ensuring maximum durability, reliability and productivity," said Carl.
"In addition, they use purpose-designed Komatsu components throughout, including the same proven Komatsu closed circuit load sensing hydraulic system (CLSS) that is used on our excavators and other equipment, including skidsteers.
"This further ensures optimum performance and reliability, because all components have been designed to work together as an integrated whole," he said.
Carl said the CLSS ensured precision and smoothness in all movements, as well as combining power and speed to respond to any need.
"Komatsu’s combination of joysticks and proportional control pedal ensure perfect control of all functions – allowing operators to use any kind of attachment for maximum versatility.
"As with other Komatsu skidsteers, we’ve also paid a lot of attention to operator comfort and safety," he said.
Both machines have the option of a large ROPS or FOPS operator cabin, either open or fully enclosed with air conditioning.
"The cabin features a wide entrance and plenty of room, providing the operator with a level of comfort that is much higher than average for this class of machine – while ergonomic controls and excellent 360° visibility make the job much easier and safer in any conditions," said Carl.
"Our Komatsu-patented LCD panel is mounted on the safety bar, allowing the operator to constantly monitor all main functions of the machine, including fuel level, water temperature, air filter, engine oil pressure and more."
Other features of the two units include:
• Low ground pressure (only 0.32 kg/sq cm for the larger CK35-1)
• High drawbar pull
• Large ROPS and FOPS operator cabin, available open or fully enclosed with air conditioning
• Low profile engine bonnet for excellent rear visibility
• Two speed travel
• Servo controls
• Komatsu universal quick coupler.
