Construction of the KS-55727 truck crane on the MAZ-6303 chassis: diagrams, description, design

Load height characteristics of the crane

The KS-55727 truck crane with a lifting capacity of 25 tons is mounted on a KamAZ-53229 truck chassis and is designed to perform loading and unloading, construction and installation work with ordinary loads at dispersed sites. The chassis of the KS-55727 truck crane has good maneuverability and ease of control, which allows the truck crane to be used with various types of access roads, and its small dimensions make it suitable for use in the cramped conditions of modern cities. The KS-55727 truck crane installation is driven by an axial piston pump, which is driven by the engine of the base vehicle through a gearbox and an additional power take-off. The winches of the lifting and turning mechanism are of the planetary type. Box-section lower frame with inclined hydraulic retractable outriggers.

The mechanisms of the KS-55727 truck crane have an individual drive with independent control from hydraulic motors and hydraulic cylinders. The hydraulic system for installing the truck crane ensures smooth control of all mechanisms with a wide range of operating speeds, as well as the ability to simultaneously combine several truck crane operations.

The four-section boom of the KS-55727 truck crane with a length of 10.08-28.08 m in the retracted position provides the truck crane with compactness and maneuverability when moving, and in the extended position it provides a large working area and a large height of cargo movement when the truck crane is operating. The ability to telescope the boom sections of a truck crane with a load allows the truck crane to perform special tasks during installation, install loads in hard-to-reach places, and carry them among mounted structures.

The safe operation of the truck crane is ensured by a complex of instruments and devices, including a microprocessor load limiter with digital display of parameters in the truck crane operator’s cabin. The load limiter can operate in coordinate protection mode, and has a built-in device for recording characteristics - a “black box” and a built-in module for protecting against dangerous voltage when the truck crane is operating near power lines.

Vehicle models

The manufacturer has developed 6 modifications of this technology based on cars. The predominant demand is for installations on the Belarusian MAZ vehicle. However, truck cranes mounted on the Urals or KAMAZ are also common in the Russian Federation.

Adapted to Russian realities, this self-propelled special equipment demonstrates the cross-country ability declared by the manufacturer at a sufficient speed. Its thoughtful design parameters have made the cranes of this brand reliable installations.

MAZ 6303A3 (6x4), YaMZ engine, boom radius 20 m, lifting height 27.1 m, lifting capacity 25 t

Modernized truck cranes with a lifting capacity of midi 25 tons KS-55727-7-13 on the MAZ-6303A3 chassis produced by MAZ OJSC are designed to perform loading and unloading and construction and installation work with ordinary loads at dispersed sites. The cranes are compact, maneuverable and balanced in weight.

The hydraulic system of the crane installation provides smooth control of all mechanisms with a wide range of operating speeds, as well as the ability to simultaneously combine several crane operations. The use of galvanized pipelines in the hydraulic system in combination with hydraulic devices from the world's leading manufacturers can significantly reduce the cost of servicing the crane during operation. The crane is designed with electrically proportional control (joysticks).

A reinforced four-section boom with a length of 10.08 m in the retracted position provides the crane with compactness and maneuverability when moving, and when fully extended, 28.08 m, it provides a large working area and a large height of movement of the load during operation. The ability to telescope the boom with a load on the hook allows the truck crane to perform special work: installing loads in hard-to-reach places, carrying them among mounted structures. The use of a telescoping hydraulic cylinder with a diameter of 125 mm made it possible to remove the intermediate clamp at the boom length of 14.08 m and increase the mass of the telescopic load to 6 tons.

The maximum size of the support contour is achieved through the use of an improved extended lower frame, thanks to which the crane is able to work with loads in a 360-degree circular zone . The ability of the truck crane to operate in a 360-degree working area minimizes the number of necessary reinstallations of the crane and increases the efficiency of its use during work.

The gearbox of the turning mechanism and winch are produced by the world leader in this field - Bonfigliolli (Italy). Planetary type gearbox with disc brakes, which meets the most modern requirements for load-lifting cranes.

The driver's cabin of a new design and modern design is comfortable and has a large internal volume. All-round glazing provides excellent visibility of the working area at any boom length and any boom angle. The use of modern materials has significantly improved heat and noise insulation. An autonomous diesel heater "Planar" is used to heat the cabin. At the customer's request, AIRTRONIC or Webasto heaters are installed.

Safe operation of the crane is ensured by a complex of instruments and devices, including the ONK-160S microprocessor load limiter with digital display of parameters in the driver’s cabin. The load limiter can operate in coordinate protection mode, and has a built-in device for recording characteristics - a “black box”, and a built-in module for protecting against dangerous voltage when working near power lines.

The creation of these crane models is the result of close cooperation between specialists from O A O MAZ and representatives of public and private construction and installation enterprises.
