Replacing the H Series: Caterpillar's new K Series wheeled loaders
The new Cat K Series small wheeled loaders, 924K, 930K and 938K, have been completely redesigned, says the company.
Incorporating a new engine that meets emissions standards equivalent to EU Stage IIIA and US EPA Tier 3 standards “significant new features deliver enhanced performance, fuel efficiency and operator comfort.”
Among those features are an efficient electronically controlled hydrostatic drive system, new optimised Z-bar loader linkage, refined operator’s station and a choice of couplers and buckets for best matching the machine to the application.
The new K Series models will replace the successful H Series models, 924H, 924Hz, 928Hz, 930H, 938H and IT938H.
The Cat C7.1 ACERT powers the three new loaders and according to Caterpillar works efficiently with the machines to deliver fuel savings up to 25% compared with H-Series models.
“An improved fuel filtration system features a dual fuel filter with increased dirt holding capacity for longer life. The C7.1 ACERT rated speed setting of 1800 rpm, compared with 2,415rpm for the H-Series, contributes significantly to reduced fuel consumption, lowered sound levels, and reduced wear. An engine-idle shutdown system further reduces fuel consumption,” says the company.
K-Series models are equipped with a step-less, four-range, hydrostatic drive system that allows independent control of ground speed and engine speed for operation of hydraulically powered work tools. A new creeper control feature further improves low-speed operations by allowing the operator to adjusted maximum ground speed down to 1.6km/hour.
The all-new operator’s station features automatic temperature control, curved front windshield, tilt and telescoping steering column, and a soft touch control panel. The electronic joystick for implement control is seat-mounted, adjustable and incorporates integral controls for auxiliary hydraulics, directional shifting and optional differential lock.
