Power unit

The excavator is equipped with an engine of its own production.

This is a water-cooled inline six-cylinder diesel engine.
It is equipped with a turbine and an intermediate heat exchanger to cool the air blown into the cylinders.
Electronics controls the operation of the engine. The ADEM A4 control unit doses fuel, reducing exhaust emissions and increasing power output.

The manufacturer indicates fuel consumption in 3 modes: light, medium and heavily loaded. Fuel consumption is in the range: 30.3-43.1; 43.1-56.4; 56.4-69.3 l/hour, respectively.

The engine cooling system is equipped with a remote radiator and a hydraulically driven fan. Air intake occurs through a membrane filter located on the rear side of the cabin.

The operator sets the operating modes of the engine using the on-screen menu on the digital display.

Hydraulic system

All power actuators in the excavator are hydraulically driven. The pressure in the system is created by two oil pumps with a total capacity of 558 l/min. The compact placement of components made it possible to reduce the total length of the high-pressure hoses and increase the efficiency of the excavator.

Due to constant pumping and high ambient temperatures, the hydraulic system is equipped with sensors that record the degree of heating.

Dimensions

The Caterpillar's parameters in terms of size cannot be called modest. Massive handles and booms are designed for excavating soil at a considerable distance (by the standards of excavator equipment) from the machine. Thus, the manufacturer indicates that the bucket can go deep to a distance of up to 8 m, and rise for loading up to 7.6 m.

Caterpillar 336D L engine

Thanks to the built-in economy mode, the operator can independently adjust the power factor in accordance with the work performed. Automatic crankshaft speed control allows for the most efficient use of fuel resources and reduces vibration levels.

The ADEM A4 electronic fuel supply unit installed on the excavator allows the engine to quickly respond to changes in power demand. High precision fuel supply is ensured by multiple injections. This allows you to lower the temperature in the firebox, reduce toxicity and optimize the combustion process.

The fundamentally new layout of the Cat C9 engine allows the cooling system components to be moved out of the engine compartment. The cooling fan speed is adjusted thanks to a built-in hydraulic drive.

The air cleaner is located behind the cabin and is a filter with radial seals and a two-layer filter mesh.

Caterpillar 336D L description

The Caterpillar 336D L Crawler Excavator is a powerful, versatile machine that can be used on construction sites and remote industrial sites.

The Cat 336D L excavator features a powerful Cat C9 engine with ACERT™ technology. The manufacturer has improved the fuel injection system, air supply and electronic control.

The air cleaner is located behind the cabin and is a filter with radial seals and a two-layer filter mesh.

The excavator cabin is sealed and protected from excessive vibration. On the left side of the cabin there is a climate control switch, which is included in the standard equipment of the machine. The most important controls are located on the right side of the workplace: attachment switches; air conditioning system; engine start switch; engine speed scale; monitor.

The cabin is equipped with a liquid crystal monitor with an extension of 400x234 pixels. When operating an excavator under standard conditions, the monitor displays 4 working zones:

The cabin mounts are rubber-metal supports, which significantly reduce noise and vibration levels. Additional safety for the machine is provided by the hydraulic system activation lever. Without putting it into working condition, the control levers do not begin to function.

Designers have taken great care to make the Cat 336D L excavator easy and safe to maintain. Access to the most important machine components that require periodic intervention and monitoring is provided from the ground level.

On the right side of the cabin there is a pump compartment - from it access to the pump and filter of the control circuit is provided. On the left side of the rotating cab is a radiator compartment that allows servicing of the heat exchanger, low-cooler and air-to-air cooler. The radiator is equipped with an additional tank and a drain valve.

A capsule filter is located outside the hydraulic tank: it protects the hydraulic system from the entry of foreign substances during the process of changing hydraulic oil. The lubrication block is located on the excavator boom, which allows the lubricant to be distributed into hard-to-reach areas of the front of the machine.

It is possible to carry out diagnostics and control the level of operating fluids using special valves for regular sampling and sampling.

The Cat 336D L crawler can work with a wide range of work tools. Excavator buckets are available for various purposes (for lightly compressed, medium-abrasive materials, for severe operating conditions, reinforced, rock); hydraulic shears; hammer; capture; seal; multiplexer; chopper; ripper, etc.

Analogs of this machine include the following models: Caterpillar 330D L ME, Hitachi S-TC300R, Komatsu PC300HD-6 avance.

Comfort and safety

The cabin is equipped with a liquid crystal monitor with an extension of 400x234 pixels. When operating an excavator under standard conditions, the monitor displays 4 working zones:

clock and tachometer (engine speed);
indicator zone (fuel level, hydraulic oil temperature, coolant temperature);
event display (machine status data);
area for other data (parameters specified by the operator).

Layout

The Caterpillar 336 is built according to the classic design for tracked vehicles. A rotating platform with a cabin and earth-moving equipment is installed on the chassis. The excavator is driven by hydraulic displacement motors driven by oil pumps.

The design of the machine is thought out to the smallest detail: access to the working mechanisms is free and maintenance or repair does not cause any difficulties for personnel.

Cabin

The operator's workplace was made comfortable.

The cabin frame is fixed to the turntable through rubber-metal shock absorbers.
The controls are placed under the operator’s right hand.
On the left side there are only climate control controls and the hydraulic system activation lever. The latter is a safety system component that prevents spontaneous initiation of actuators.

The excavator is equipped with a comfortable sprung seat with the possibility of electric heating. The seat can be adjusted in three planes, which allows it to be adjusted to the physiological parameters of the operator.
