November 2010, Vol. 65 No. 11
Case Construction Equipment's CX800B excavator.

The Cat 336D L Hydraulic Excavator features a standard heavy lift circuit — at the touch of a switch, heavy lift will boost hydraulic pressure for increased lift performance. The 336D L has a maximum operating weight of 82,962 pounds and net power of 268 hp. The Cat C9 engine powers the 336D L and meets U.S. EPA Tier 3 emissions regulations. To enhance durability in demolition applications, the 336D L 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.
