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.
