Powered by a Caterpillar C4.4 ACERT engine meeting U.S. EPA Tier 4 Interim/EU Stage IIIB emissions standards, the company's new 450F backhoe loader retains the 450E's versatility, available with a hydraulic thumb, pin-puller-type coupler, and a range of compatible work tools, including buckets with integral forks, hammers, and plate compactors. The machine will be available during the second quarter of 2013.
With 5% more gross power than the 450E, the 450F has added capability for aggressively digging in stubborn banks and stockpiles, for maintaining faster road speeds, and for more easily climbing grades.
The engine delivers 396 lb·ft (536 N·m) of torque and has a torque rise of more than 30%. An Automatic Engine Speed Control feature reduces engine speed if hydraulic functions are idle, contributing to increased fuel efficiency and reduced sound levels.
The 450F incorporates a closed-center, load-sensing hydraulic system that uses an "extremely efficient" variable-flow main pump, which is now electronically controlled to provide enhanced power management and response, resulting in more precise control of backhoe and loader functions, added productivity, and increased fuel economy. A replaceable-cartridge hydraulic filter allows environmentally friendly disposal. For operator convenience, the loader is self-leveling and incorporates a return-to-dig feature.
Other design features that add to the 450F's reliability and ease of maintenance include a composite fuel tank that reduces condensation and resists rust, new electric fuel-priming pump that simplifies routine service, single-plane cooling package for improved efficiency and easier cleaning, engine-sump drain tap for controlled oil evacuation, relocated primary fuel filter that is easily accessed, standard battery-disconnect switch, and relocated engine ECM (electronic control module) that facilitates trouble-shooting.
The 450F operator's station features an air-suspension seat and ergonomically designed joystick controls. A redesigned gauge cluster simplifies navigating through system information and control settings, and an available Machine Security System utilizes a programmable key to deter theft, vandalism, and unauthorized usage.
Standard equipment includes a 5F/3R AutoShift transmission, with four wheel drive and the Cat Ride Control system, which smoothes the machine's ride, whether on the jobsite or the highway, whether the bucket is loaded or empty.
Optional equipment for the 450F includes an extendible stick, deluxe cab with air-conditioning, cold-weather package, third-function loader valve, six-function backhoe valve, auxiliary hydraulic lines, and the Cat Product Link telematics system that reports machine location and operating parameters via a secure website.
