EO-33211

The EO-33211 excavator is designed to excavate unfrozen soils of category I-IV, as well as previously loosened rocky and frozen soils with pieces no larger than 200 mm.

It is used in the development of quarries, digging pits, trenches, canals and other similar structures.

Excavator EO-33211 is available in the following versions:

• Option 1 - "Standard" - adapted for operation in cold climates at ambient temperatures ranging from -40°С to +40°С;
• Option 2 - "Tropical" - adapted to work in a tropical climate at an ambient temperature ranging from -20°C to +55°C.

Composition, device and operation of the excavator

The EO-33211 excavator is a single-bucket, universal, full-revolving machine on pneumatic wheels with an individual hydraulic drive of all mechanisms, with a rigid suspension of working equipment.

The excavator consists of a pneumatic-wheel undercarriage (chassis), a turntable, working equipment, a hydraulic system, a pneumatic system, electrical equipment, and spare parts.

The chassis of the excavator is a pneumatic-wheel undercarriage, consisting of a running frame with a slewing bearing, folding supports, a blade, a gearbox, front and rear axles equipped with dual-slope chamber wheels and connected to the gearbox by cardan shafts, a wheel rotation control mechanism, as well as units of the hydraulic control system and pneumatic control system for wheel brakes.

The pneumatic wheel running gear is driven by two hydraulic motors mounted on the gearbox flange.

Pneumatic undercarriage provides movement on work sites and on roads, as well as the ability to tow an excavator.

On the turntable there are: a power plant, a drive for turning the platform, a fuel tank, a hydraulic tank, pneumatic system units, distribution and valve devices for hydraulic equipment and hydraulic control, pipelines and a counterweight. In the left front part is the cabin, which houses the controls.

The movement of the working bodies (arrows, sticks, bucket) is carried out when the working fluid is supplied to the piston or rod cavities of the hydraulic cylinders.

The wheel brakes and the parking brake are controlled pneumatically.

The drive mechanism of the stroke, as well as the control of the working bodies of the excavator and steering - hydraulic.

The excavator uses electric systems for lighting, ventilation, signaling, and starting a diesel engine, which provide the ability to work at any time of the day, a normal microclimate in the driver's cab.

Ease of workflow management and ergonomics

The design of all elements of the operator's cabin, made in accordance with ergonomic requirements, provides comfortable working conditions, and the controls, which are particularly simple, ensure that the operator performs functional operations throughout the working day, which causes minimal costs for the training of qualified specialists.

The cab contains levers, pedals and an excavator control panel, a remote control chair, a box for technical documentation and first aid kits, a fan, a sun visor, a coat hook, a fire extinguisher, and there is also a place to install a thermos.

The cabin is sound and heat insulated, has glazing that provides an overview of the working area. The front glass of the cab is equipped with two wipers.

Cabin heating

The excavator cab is heated from the engine cooling system using the heater OT-2 U2-24-05 TU 3-760.0-93. To protect against mechanical damage, the heater is installed on rubber shock absorbers and is closed from above with a metal cover.

Cabin

The driver's cab is metal, closed, with one door, sound and heat insulated, protected from dust and moisture.

The cabin has glazing that provides a good overview of the working area.

The chair-remote consists of a pillow, backrest, for placing control columns, sidewalls are attached to the chair.

Cabin equipment

Cabin equipment includes: fire extinguisher, first-aid kit holder, thermos, three windshield wipers, clothes hanger, fan, rear-view mirror, dome light, sun visor.

Maintenance

Good access to all components and their well-thought-out design make it easy to maintain and repair the excavator in any, even non-specialized workshops.

Automatic control and alarm system

The excavator is equipped with an automatic control and alarm system - an indication and alarm unit.

Warning signaling is carried out by a light board and signal lamps built into the buttons. The activation of the warning alarm is accompanied by a sound signal lasting 6-10 s.

Governing bodies

Controls include: a steering column with a brake pedal and a parking brake control valve, an engine speed control lever, a safety lever, a platform slewing stop, an “action” pedal, a pedal for reducing travel blocking and switching “support-bulldozer”, a “floating” pedal lowering the boom. Part of the controls are located on the operator's console chair: the boom and bucket control handle, the travel direction switching handle, the support and bulldozer control handle, the platform rotation control handle, and the travel speed shift handle.
