EXTRA-ROAD CRANE TRUCKS QAY160 and QAY200
Crane trucks QAY160 and QAY200 - these are the giants, which combine in themselves advanced technologies and developments in the field of creating the hoisting machines at the pneumo-wheel motion.
LOAD-LIFTING EQUIPMENT
Load-lifting arrow has the egg-shaped or U- descriptive form of
profile. Egg-shaped form ensures the assigned strength of arrow with the smaller
thickness of the walls of sections. This makes it possible to use more than
sections and to create the arrows of gigantic sizes (to 61m). With the equal
strength, the arrow of egg-shaped profile has 6 sections, against 4 sections of
arrow U- descriptive profile.
Arrows are
made made of German high-strength steel and is passed ultrasonic checking to the
absence of flaws. The special devices of the levelling off of arrow and the
supporting sliding elements of new construction are used. Device of automatic
blocking and pinning for arrow U- profile (patent). Automatically controlled
system of telescoping arrow with one cylinder (patent). Adequate lubricant of
the surfaces of sections. Imported ropes
On
the crane is used the limiter of moment of load PAT. The drum of system,
installed on the arrow, automatically regulates the length of cable with
telescoping of arrow. Two independent load-lifting winches are completed by the
imported derotatsionnymi ropes.
POWER PLANT And THE CHASSIS
On crane trucks QAY160 and QAY200 are established two engines. Turbodizel' Volvo TAD720VE is used for the actuating of crane installation, and BENZ OM502LA - as the power plant of chassis.

Automatic transmission with manual and automatic control and
extra-road casings MICHELIN make possible for crane to be moved easily and
rapidly, even on the broken ground. Onboard electronics is built on basis of
Can- beads of technology and will use digital interaction of components.
Anti-blanking and antiprobuksovochnaya systems ensure stable braking and safe
control of machine.

Hydropneumatic suspension, with the individual hydraulic cylinders
to each axis, makes it possible to change clearance directly from the cab of
driver. System has a function of the automatic flare function depending on the
road conditions (patent). In the cab of driver the pressure gauges in the
hydraulic cylinders of suspension are established. With the movement with the
suspended load, the suspension is blocked.
AUTRIGERY
Electrical control of autrigerami with the button "acceleration". With
completely advanced autrigerakh, crane installation can be turned on 360°.
Visible in the darkness levels from both sides (patent). By autrigerami can be
governed both simultaneously all and each separately. Work is possible, with the
advancement of autrigerov not to entire length.
MANEUVERABILITY
In spite of their imposing sizes, crane trucks possess outstanding maneuverability. When the wheels of front and rear axles are turned to the different sides, is reached the minimum the diameter of turn (24m in cranes QAY160 and QAY200). If all wheels are turned to one side, then machine can move by crab. Furthermore, crane trucks are capable of overcoming the significant lifts (cranes QAY160 and QAY200 - 48%). Such characteristics are allowed for crane trucks rapidly and easy to occupy advantageous positions of those relatively raised it is cargo.
ADMINISTRATION SYSTEM With INTEGRATED Plc the hydraulic SYSTEM
The load-lifting mechanism of crane truck is governed by
integrated PLC- computer, designed for the construction vehicles. Pilot signals
and map of productivity can be established and adjusted with the use of
numerical data. Control system, connected with the hydraulic system of variable
working volume, it can automatically and accurately regulate productivity and
pressure on the basis of the data about the variation of load. This ensures the
smooth work of crane and the high accuracy of its control.
The controlled by
pump, hydraulic system of open type variable working volume, united with the
hydro-electric linear regulation ensures high productivity. Are used imported
hydraulic hoses with the metallic carbines, effective cooling system of oil of
hydraulics. The hydraulic system of a constant power copes by pump with the
variable working volume (patent). Hydraulic system of turning with the damping
and the self-regulation (patent). Hydraulic cylinder with the automatically
revolving piston rod (patent). Imported pump, hydraulic motor, valves and
packing. High(ly)-integrated modular unit of valves with the simple channel and
the decreased hydraulic resistance (patent).
COMBINED COUNTERWEIGHT
The extra-road cranes QAY160 and QAY200 are equipped with the
combined counterweight. Using different combinations of counterweight, it is
possible to optimally dispose crane under the specific conditions for lift it is
cargo. In this case is regulated not only the maximum mass of the raised load,
but also height and the distance of its lift.
Maximum load
capacity
QAY200:
with counterweight to 65t or 42t - 200t
with
counterweight to 32t - 198,7t
with counterweight to 22t - 190t
without the
counterweight - 172t
QAY160:
with counterweight to 45t or 32t -
160t
with counterweight to 22t or 11t - 130t
without the counterweight -
125t
ERGONOMICS And THE COMFORT
Cab of the driver
Spacious contemporary cab. Good
soundproofing, adjusted driver seat and the steering column. Air conditioner,
the heater of wind glass.
Cab of the operator of the crane
The
cab of new design is prepared from the composite material. Front rounded window
from the safe glass with the wide field of view. The adjustable seat. The
internal finishing of cab has aesthetical form and good noise-isolation. Air
conditioner and heater optionally can be established. Shutters for the
protection from ultraviolet irradiation. Multifunctional limiter of moment of
load. Contemporary electronic joystick with the linear dependence. Built-in
radio tape recorder. For convenience in the operator, the cab can be slanted
back to 20°.

THOUGHT-OUT CONSTRUCTION
The structural details of chassis and load-lifting mechanism are made made of high-quality high-strength steel, and they are calculated with the aid of the program set ANSYS. The main carriers are made made of high-strength steel WELDOX 960, which possesses the heavy stock of strength. Imported high-precision contemporary industrial equipment with CHPU makes it possible with the high accuracy to reproduce in the metal complex constructions.
