The new Caterpillar E-Series backhoe loaders — the 416E, 420E and 430E — deliver increased performance, operator comfort, controllability, versatility and new, functional styling when compared to the D-Series models, which the new machines replace.
The 420E and 430E are offered in integrated tool carrier configurations for applications that benefit from parallel-lift loader linkage and the versatility of quick work tool changes.
The 420E has 89 net hp (66 kW) and a backhoe digging depth of 14 ft. 4 in. (4.36 m) when equipped with a standard stick.
The 430E has 97 net hp (72 kW) and a backhoe digging depth of 15 ft. 5 in. (4.70 m) when equipped with a standard stick.
An extendible stick pushes the 420E digging depth to 17 ft. 11 in. (5.46 m) and the 430E digging depth to 19 ft. 6 in. (5.95 m).
The 74-net-hp (55-kW) 416E offers the same digging depths as the 420E. The 416E also is available with an optional turbocharged engine that boosts net hp to 89 (66 kW).
High Performance
Hydraulics Get Stronger
The 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. The new flow-sharing hydraulic valves ensure proportional hydraulic flow to all implements and improve multi-function performance, according to the manufacturer.
The 420E features a 14 percent increase in backhoe stick breakout force and is approximately 10 percent more productive than the previous model.
The 430E features increased lifting and breakout forces. Swing forces are increased, too. The result is aggressive trenching performance and improved backfilling capability.
On the loader end, truck-loading performance is improved through pump torque limiter changes and improved balance of power distributed to the drive train and hydraulics.
New Cab and
Redesigned Operator Station
The new cab with curved glass and contoured fenders gives the E-Series a distinct new look, improves serviceability and provides better visibility, according to the manufacturer. The low hood enhances sight lines to the loader, and the hood tilts forward for easy access.
The redesigned operator station maximizes operator comfort and productivity. Standard pilot operated joystick controls are easy to use, and they reduce operator fatigue and increase efficiency.
Auxiliary backhoe hydraulic functions such as extendible stick or hammer operation are controlled with thumb rollers. Roller switches eliminate the need for foot pedals and create more room in the cab.
Other new features in the E-Series include a narrowed front dash, foot operated tilt steering, and in-cab control pattern changer for the 420E and 430E.
Additionally a new air conditioning system produces 20 percent more airflow. The intake for the system has been relocated for cleaner air, and access to filters is easier.
Enhanced Drive Train
and Travel Performance
New Cat axles and a modified transmission increase top travel speeds 25 percent to 25 mph (40 kmh). The all-new mainframe has a 4-in. longer wheelbase for improved balance and machine stability. The 430E also features a larger torque converter for higher rimpull and better tractive effort, which can aid truck loading and stockpile work.
Each model has stronger brakes and increased slope holding capabilities.
The 420E and 430E brake systems have power boosters. Outboard planetary gears and brake wear check ports allow easier service.
New Extendible
Stick, Bucket Thumbs
The new extendible stick has an external slider design for better performance, strong digging forces and more versatility. The outer slider protects the inner slider from damage and debris.
With the introduction of the E-Series backhoe loaders, Caterpillar is offering factory-installed thumbs.
The new thumbs are available in both hydraulic and stiff-link versions and are compatible with all bucket and coupler combinations. The thumbs enable the operator to handle irregularly shaped objects more easily.
Also adding to versatility, the combined function auxiliary hydraulic lines handle all one-way and two-way hydraulic work tools on the backhoe. In addition to thumbs, such tools include hammers, compactors, augers and tilting couplers.
Enhanced Onboard Electronics
AccuGrade BHL site reference system is a grade and depth check system that provides accuracy, productivity and low operating costs. It also provides a platform for future technology.
The new backhoe loaders also are available with Product Link, a management tool that allows customers to collect and track multiple types of information about their machines via wireless communication. Managers can monitor machine location and service meter hours as well as machine health and productivity.
