Cat launches ‘Next Generation’ line of excavatorsPublished 3/7 at 12:37
The new 36t excavators from Caterpillar, the 336 and 336 GC ‘Next Generation series’, have been developed to increase operating efficiency, lower fuel and maintenance costs, and improve operator comfort compared to previous models.
The new excavators offer unique combinations of features designed to match contractors’ productivity and cost targets.
Delivering high production performance, the new Cat 336 features standard integrated Cat Connect technology and the most power and lift capacity of the two models. The result is high productivity at low cost. The new Cat 336 GC combines a balance of productivity features with reduced fuel consumption and maintenance costs. The result is high reliability and low cost per hour performance.
The new Cat 336 is said to have the industry’s highest level of standard factory equipped technology to boost productivity. Integrated Cat Connect technology increases operating efficiency by up to 45% over traditional grading operations. The standard Cat Grade with 2D system provides guidance for depth, slope, and horizontal distance to grade through the standard touchscreen monitor. The system is readily upgradable to Cat Grade with Advanced 2D or Cat Grade with 3D.
Standard Grade Assist automates boom, stick, and bucket movements so operators can effortlessly stay on grade with single lever digging. Cat Payload delivers precise load targets and increased loading efficiency with on the go weighing, and real time payload estimates, without ‘swinging’ to prevent truck over/under loading. The E-fence feature prevents the excavator from moving outside operator defined set points which is particularly useful when working beneath structures or near traffic. Furthermore Cat LINK hardware and software connect jobsites to the office, providing customers with machine critical operating information.
The two new models have been designed to consume less fuel with the 336 delivering savings of up to 15%. New Smart mode operation automatically matches engine and hydraulic power to digging conditions, optimising both fuel consumption and performance. Engine speed is automatically lowered when there is no hydraulic demand to further reduce fuel usage. The cooling system features a new fan that runs on demand to keep the excavator working at the correct operating temperature. With a new electrohydraulic operation, the models feature a new main control valve that eliminates the need for pilot lines, reduces pressure losses, and lowers fuel consumption. Fewer hydraulic lines on the excavators result in less oil required, lowering long term operating costs.
The new Cat excavators have been developed to reduce maintenance costs by up to 15%. A new air filter with integrated pre cleaner and primary and secondary filters, has improved the dust holding capacity of the previous design. The new hydraulic return filter has a 3,000h service life, estimated to be a 50% increase over the previous filter. The fuel system, water and sediment drains, and hydraulic system oil level, are positioned close together at ground level, making routine daily maintenance faster, easier, and safer.
With a choice of three cab packages, all ‘Next Generation’ excavator cabs come equipped with standard features including keyless push button start, large standard touchscreen monitor with jog dial keys for control, and sound suppressed rollover protective structures (ROPS). New advanced viscous mounts reduce cab vibration and a Bluetooth integrated radio with USB ports for connecting and charging phones bring enhance usability. Automatic climate control maintains internal cab temperature settings regardless of external ambient temperatures, with a programmable joystick enabling the operator to ‘dial in’ productivity settings.
