Cat 340 replaces the Cat 336

The 45-ton 340 Cat excavator replaces the Cat 336 with a 10-percent boost in productivity, according to the company. The Cat C9.3B diesel provides 347 horsepower, and the Cat 340 digs to almost 27 feet. It has a 7.5-ton counterweight.

Three engine modes are available. Power mode delivers maximum power; Smart mode automatically matches engine and hydraulic power to digging conditions; and Eco mode reduces engine speed to a constant 1,500 rpm.

Synchronized 1,000-hour oil and fuel filter service intervals eliminate labor cost for nine oil and fuel filter changes and parts cost for 27 oil and fuel filters over 10,000 machine operating hours, according to the company.

Next Generation cab options include Deluxe cabs with a heated air-suspension seat and Premium cabs come with a heated and ventilated air-suspension seat. Both have a tilt up left-hand console for easier access in and out of the machine.

A touchscreen monitor and jog dial offer quick navigation through machine controls and provide easy access to the machine’s digital operator’s manual. Keyless pushbutton start is standard, and Bluetooth key fob is available. An Operator ID passcode allows for engine starting and can quickly save and restore joystick button, response, and pattern preferences for individual operators.

Standard technologies include Cat Payload on-board weighing, Grade Assist for maintaining grade, and 2D Grade with depth and slope indication. Auto Hammer Stop warns operators after 15 seconds of continuous firing and then shuts off the hammer after 30 seconds to prevent wear and tear. Auto Dig Boost and Auto Heavy Lift increase bucket penetration and lift capacity by 8 percent over the Cat 336, and Lift Assist helps operators avoid tipping the machine.
