The operator's cab is designed according to the latest ergonomic principles. The over-size windows provide an unobstructed panoramic view of the entire work area. Automatic climate control is standard; sensors continuously monitor the temperature settings to ensure operator comfort.
Critical service points are all concentrated in one location, which is easily accessed from the ground. The swing drive is completely maintenance free due to the semi-automatic central lubrication system.
C-series Travels on Both Wheels and Tracks
Volvo's C-series excavators include the EC160C and EC210C crawler models and the EW160C and EW180C wheeled versions. The models offer operating weights from 36,155 to 51,200 lbs. and power ratings from 117 to 152 hp. Maximum digging depths range from 18.7 to 24 ft., with breakout force from 25,066 to 33,069 lbs. Lifting capacity spans from 11,199 to 16,975 lbs.
Specific to the EC160C and EC210C is a strengthened high-tensile steel undercarriage frame and sealed-for-life greased track link. The EW160C and EW180C feature a strong undercarriage that enables jobsite speeds up to 22 mph. The dozer blade and wide-gauge outriggers allow the units to lift, load or grade as required.
All C-series models are equipped with more powerful, Tier III-compliant Volvo engines utilizing V-ACT (Volvo Advanced Combustion) technology. High torque at low revs allows for more efficient fuel consumption. The onboard computer balances maximum available power to hydraulic output, preventing the engine from becoming overloaded, regardless of engine speed or pump demand.
Intelligent hydraulics include boom, arm and swing priority. In-cab operator-selectable hydraulic flow and pressure increase performance, especially when regularly changing attachments. A hydraulically driven fan operates only as needed.
The Care Cabs offer more room, improved visibility, a multi-adjustable seat, pedals and joystick, enhanced suspension system for reduced vibration and electronic climate control. In-cab noise has also been significantly reduced.
Caterpillar's Largest Backhoe to Date
With a standard backhoe digging depth of 17 ft. 3 in., the 450E is the largest backhoe-loader in the Caterpillar lineup. A new extendible stick pushes digging depth even further to 21 ft. 4 in. A pilot-operated joystick control system allows for ease of backhoe operation.
Loader productivity is also greater than the previous model (446D) due to a larger bucket, increased hydraulic flow and stronger rimpull. The general-purpose loader bucket offers a 1.75-cu.-yd. capacity.
High-rotation backhoe linkage eliminates the need to change pin position when moving from loading trucks to vertical wall trenching. Thumb-ready sticks permit easy thumb installation. New combined-function auxiliary hydraulic lines on the backhoe support all one-way and two-way hydraulic work tools. A variable-displacement piston pump and closed-center, load-sensing hydraulics provide quick implement response and speed, as well as high forces at any engine speed.
Power is supplied by an electronically controlled Cat C4.4 four-cylinder, Tier III/Stage III emissions-compliant engine. The unit also incorporates four-wheel drive and ride control. New Cat axles and a modified transmission increase top travel speeds 25% to 25 mph.
To further enhance the efficiency of its backhoe-loader line, Caterpillar is providing the AccuGrade machine control and guidance system as a factory-installed option. Two systems are available. The site reference entry-level grade and depth check system enables the operator to excavate to pre-determined coordinates. The more advanced laser reference system utilizes an off-board laser transmitter to set a grade reference; it is available factory installed or as an easy upgrade from the site reference system.
Industrial loader addition
Caterpillar broadens its industrial loader line with the addition of the 414E IL, featuring seat-mounted joystick implement controls. With just one joystick, the operator gains full control of all five functions (raise, lower, float, tilt and pitch) of the three-point tool carrier, along with the ability to activate auxiliary hydraulics and work tools.
