The front-end wheel loader PK-46 is the
up-to-date efficient machine designed to perform the
excavation works, loading and developing the dissimilar
materials: the various types of grounds and rocks‚ coal,
sand, crushed stones, metal and wood chips, stones, etc as
well as the agricultural products. Besides, the loader is
able to process the grounds independently (fill the earth
banks, barrages), to work in the bulldozer mode of
operation: to level the grounds and to dig out the shallow
trenches. The front-end loader is much less in its external
dimensions and weight than the earth-moving machines and is
able to lift a lot more lading weight. It does not require
the large area for the maneuvering. Exactly these features
specified the PK-46 application field. That is one of the
basic construction and highway machines.
 The high mobility of the front-end loader
PK-46 is achieved due to the articulated frame consisting of
two parts connected to the vertical axle with a joint. The
lock and the swivel of the frames relative to each other is
performed with the help of two hydraulic cylinders
controlled by the steering system of tracking type ensuring
the frames relative turn to the angle proportional to the
steering wheel turn angle. The rear frame is designed to
mount the power plant, transmission, rear axle and operator
cab; the front one - to fasten the working equipment to the
hydraulic actuation system and front axle.
The specially designed reliable tires are
installed on the loader. They not only ensure the tractive
effort sufficient for the effective operation but are able
to function as the shock absorbers.
When designing the loader much attention was
given to the ease of maintenance including the diagnostic
assistance plus the operator comfort.
The loader design is the combination of the
reliable units of high-level productivity, security and
comfort. The following features specify our loader:
adjustable steering column produced by the Italian company "FORSHEDA
POLIPAC", versatile control level, diesel engine JAMZ-236
widely used throughout Russia, transmission manufactured by
the company ZF Zahnrad Fabric (Germany), easy access to the
engine and to the cooler, high-performance cab heating
system (minus 35 С outside, plus 25 С inside). The noise
level in the cab during the operation does not exceed 78.
The attached implements' hydraulic system units with the
proportional control by the company "DANFOSS" are applied.
The kinematic bucket return from the unloading position to
the ground loading position is automatic. The front
headlights "COBO" (Italy) are used.
Operator Working Place
Control Devices
The control-and-measurement devices of the loader units and
of the lighting controls are located on the steering column.
The Driven Elements ControllingThe Driven Elements Controlling is performed with the help of a
single eight-position handle (joystick). The control is
proportional servohydraulic. The driven elements
displacement speed depends on the handle inclination angle.
Seat "PILOT"
The up-to-date seat "PILOT" ensures comfort operation and
excellent vibration insulation as well as decreases the
operator fatigability and offers the sense of reliance. The
seat meets the requirements of the European standards.
Steering Column "FORSHEDA POLIPAC"
It comprises a cage, hydraulic steering wheel,
integrated device panel, switches and indicators. The
gearbox control lever is located at the left; the
under-steering wheel switch is at the right. To ease the
operation performance, the steering column can be adjusted
according to its inclination angle.
Comfortable and Up-to-Date Cab
Fan
The two-mode combined extract and input fan with the
adjustable air distribution provides the required
comfortable conditions for work.
Gas Stops of Hood and Cooler Enclosure The side doors of a hood are easily opened and reliably fixed in
the open position due to the gas stops.
Gas Stops of DoorGas Stops of Door The cab
doors are equipped with the gas stops installed in the way
to provide smooth door pull and lock when they open.
Loader Cab
It is all-metal structure with the safety system ROPS-FOPS.
It is installed on the shock absorbers: this facilitates
noise and vibration level decreasing. The right-hand door is
designed with the drop window. The excessive air pressure
pressurized in a cab prevents from the dust and moisture
penetration. The cab is equipped with a heater and a
combined extract-and-input fan.
Transmission and Undercarriage
Transmission ZF 4WG-160 is designed with four front and three rear gears and with the
electric hydraulic speed control.
Upper Cardan Shaft
is designed for torque transfer from the power take-off
reduction gear to the transmission.
Lower Cardan Shafts
are designed for torque transfer from the transmission to
the front and rear driving axles.
Interchangeable Driving Axles transfer the torque from the cardan gear to the wheels. The
front axle is a loading equipment rigid support.
ПЖД-30 Starting Preheater of Engine is a high-performance liquid diesel heater.
Axial-Piston Hydraulic Pump
ensures operation of the attached implement hydraulic
system.
