Performance

The Cat® C7 with ACERT„¢ Technology offers more engine power and runs at lower speeds for better fuel economy and reduced wear.

Automatic Engine Speed Control

The two-stage, one-touch control maximizes fuel efficiency and reduces sound levels.

Engine Controller

ADEM„¢ A4 (Advanced Diesel Engine Management) controller uses sensors throughout the engine to manage engine load and performance. The ADEM„¢ A4 controller is the muscle behind engine responsiveness, self-diagnostics, controlling emissions, and fuel economy.

Fuel System

The Cat® C7 ACERT„¢ engine features electronic controls that govern the mechanically actuated unit fuel injection (MEUI) system. Multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycles lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.

Cooling System

To reduce fan noise, the cooling fan is driven from a viscous clutch that is electrically controlled by the machine ECM. It calculates optimum fan speed based on the target engine speed, coolant temperature, hydraulic oil temperature and actual fan speed. The Cat® C7 ACERT„¢ engine delivers a completely new layout that separates the cooling system from the engine compartment.

Air Cleaner

The radial seal air filter features a double-layered filter core for more efficient filtration and is located in a compartment behind the cab. A warning is displayed on the monitor when dust accumulates above a preset level.

Operator Station

Designed for ease of operation, high visibility, and comfort, the operator station allows the operator to focus on production. With the material handling job in mind, this machine is equipped with a 2.6 m (8'6") hydraulic cab riser to maximize viewing to all sides of the machine.

Operator Station

To maximize visibility, all glass is affixed directly to the cab eliminating the use of window frames. 50/50 split front windshield allows both upper and lower portions to be stored in the overhead position. The upper front windshield open,closes, and stores on the roof above the operator with a one-touch action release system. Parallelogram wiper covers almost the complete front window without leaving unwiped areas in the immediate line of sight of the operator.

Structures

The structural components are the backbone of the machine's durability. Caterpillar design and manufacturing techniques assure outstanding durability and service life.

Purpose Designed Upperframe and Counterweight

The upperframe is specifically designed for the scrap and material handling markets. It is built of heavier strength material and thicker steel sections to handle the increased swing loads developed with the longer front parts, heavier counterweights, and cab risers used in material handling.

Strong and Stable Undercarriage

The M325D MH and M325DL MH wheeled undercarriages provide maximum rigidity and long service life.

The hydraulic lines are routed through the frame, and the cylinders have heavy-duty guards to provide protection from damage. The front axles on M325D MH and the rear axles on M325D LMH offer great oscillating and steering angles. The transmission is mounted directly on the rear axle for protection and optimum ground clearance. The M325D MH includes 4 dual 12.00-20 solid rubber tires, and the M325D LMH is equipped with 4 single 16.00-25 solid rubber tires. Optional pneumatic tires are also available. A large toolbox is provided.

Material Handling Front

The two front options meet your material handling needs with excellent lift performance and working range whether operating in close or at full reach. Built for strong performance and long service life.

Efficient Design of Welded Box-Section Sections

The design with thick, multi-plate fabrications in high stress areas allows structures to flex, dissipating stresses, and maximizing strength.

Finite element analysis is used in the determination of structural stresses and enables optimization of durability and performance. Castings and forging are used in critical high-load areas such as the boom nose, boom foot, and boom cylinder connection. Internal baffle plates provide additional strength and durability throughout the structure to withstand torsional loads.
