Caterpillar Introduces the New 336DL Hydraulic Excavator

The Cat 336DL Hydraulic Excavator features greater performance, flexibility and versatility compared to the C-Series model. A new, spacious cab and new styling also set the D-Series apart from previous machines. And additional guarding for demolition applications helps ensure reliability and durability in demanding tasks.

The 336DL has more engine power and hydraulic pressure than the C-Series model. The result is increased breakout force and greater lift force, which create faster cycle times and superior productivity. The heavy lift circuit is now standard on D-Series models. At the touch of a switch, heavy lift will boost hydraulic pressure for increased lift performance.

The 336DL has a maximum operating weight of 82,962 pounds and net power of 268 horsepower.  The Cat C9 engine powers the 336DL and meets U.S. EPA Tier 3 emissions regulations. The engine management system provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. For reduced power consumption and reduced noise, the excavator has a hydraulically driven fan controlled by the electronic control module.

To enhance durability in demolition applications, the 336DL can be equipped with heavy-duty triple grouser tack shoes for long wear and solid traction. Track guards for the sprocket end and idler end are fitted to protect the full length of the track.  Rubber bumpers attached to the sides of the excavator reduce inadvertent damage when swinging, and bottom and bearing guards protect those areas from damaging debris.

Additional cab guarding includes a full-length wire mesh window cover and a falling object guarding system. The spacious cab features glass affixed directly to the pillars to eliminate window frames and enhance visibility. A large skylight provides a view upward. Joystick controls have low lever effort and are designed to match the operator’s natural wrist and arm position. The operator can operate joystick controls with an arm on the armrest. 

For expanded versatility, many factory-installed options are available. The 336DL features a wide range of factory-installed auxiliary hydraulic systems, including a one-way, high pressure, high flow circuit for hammers. Also, a two-way circuit is available for thumbs and other hydra-mechanical work tools.

Another option is the Tool Control System for D-Series models. The Tool Control System is exclusive to Caterpillar and allows operators and technicians to set auxiliary hydraulics flows and pressures by using the monitor in the cab instead of using expensive service tools. The customer can pre-set and store as many as 10 flow and pressure settings for 10 different hydra-mechanical work tools.

The Tool Control System is available in two factory-installed configurations - as a stand-alone system or with a medium pressure circuit and third pump. The latter system handles tools that require rotate function, such as multiprocessors or rotating grapples. It also can handle hammers, thumbs and similar tools. Single-function and double-function hydraulic tool systems also are available as a factory installed attachment

An expanded line of work tools is available. For fast work tool changes, two different quick couplers are available - a dedicated quick coupler and the Center-Lock Pin Grabber coupler. The latter uses a patented over-center locking mechanism and two hydraulic locking features to assure positive work-tool attachment. The new over-center locking technology promotes jobsite safety and allows operators to quickly, simply and confidently engage and disengage work tools regardless of boom and stick position.

To aid in machine management, Caterpillar offers Product Link. The optional system provides information on machine location, service hours and machine health via wireless communications.
