Truck crane KS 3577 4 technical characteristics. Load height characteristics of the crane

Fast, maneuverable truck cranes with a small lifting capacity are also needed in construction, just like multi-ton trucks. They can quickly get to the site, and the simplicity of the design allows you to start working without complex preliminary preparation. An example of such crane equipment is the KS-3577 truck crane.

All about the crane installation KS-3577

A multifunctional and universal truck crane came off the assembly line of the Ivanovo Automobile Plant. The base vehicles to which this crane equipment was supplied were the following models: MAZ-5334 and MAZ-5337.

Main components of boom equipment

The KS-3577 truck crane is technically equipped so that it can be used in various lifting operations, performing unloading and loading operations or participating in the installation of building structures weighing no more than 16 tons.

Boom equipment

Traditionally, like most truck cranes, the KS-3577 model is equipped with a telescopic boom design. The lifting organ itself consists of two parts: a fixed one, hinged to the support, and a movable section, which can be pulled out. The lifting of the main supporting part of the boom is provided by the main hydraulic cylinder. Two hydraulic cylinders connected to each other using a coupling are responsible for extending the second section.

Boom extension

A jib or extension is provided to increase the working space under the boom, as well as the height of the latter. In the KS-3577 truck crane, this element is made of rolled metal (angle) and is attached to the head of the retractable boom section using special brackets. The jib can be transported on the KS-3577 itself, attaching it next to the boom to its side plane.

Operator's room, truck crane rotary unit, lifting body

KS-3577 is a lifting system that operates hydraulically. The working bodies are driven by a hydraulic pump, which itself is connected through a box to the power take-off shaft of the vehicle. The crane operator can use a special lever in the cabin to disconnect the pump from the drive.

Platform rotation mechanism

The unit is made on the basis of a hydraulic motor, which is connected to a two-stage gearbox. There is also a shoe type brake and a hydraulic release. The output part of the gearbox has a gear on the shaft. The latter engages with the turning-support circle via a gear ring. The rotating part of the truck crane can be rotated manually using a handle. To do this, there is an intermediate shaft with a gear with a shank at the end.

Crane operator's cabin

The driver operating the KS-3577 truck crane is in a special cabin during lifting operations. All machine controls are located in this workroom. The cabin is equipped with lighting equipment, a cooling fan, and has spacious viewing windows. For work in winter period heating of the workplace is provided, the cabin body itself is thermally insulated.

Lifting mechanism

The cargo winch is driven by a hydraulic motor through a two-stage gearbox. It itself has a drum with a braking method through a band brake and a hydraulic release. The drum communicates with the hook suspension through a special cable.

Electric filling

The KS-3577 truck crane is a modern machine with a basic set of electrical equipment, which includes security systems, measuring instruments, and lighting equipment. All these electronics are powered by a 24 volt generator.

Safety

Safety devices designed to ensure safety when a truck crane performs lifting operations are represented in the KS-3577 by limiters: exceeding the maximum load weight, boom extension and reach, and the height of the load lifting level. There are also all kinds of sensors and alarms.

Applicable chassis

The KS-3577 crane is mounted on a two-axle chassis of a MAZ vehicle with a 4x2 wheel arrangement.

Characteristics of the crane installation

KS-3577, like any other crane, has certain characteristics that allow you to understand what tasks this special equipment can solve.

Technical capabilities

• The maximum weight of the truck crane lifting load is 16 tons;
• Boom size – 14 meters;
• Speed ​​when moving the load up and down – 10 meters per minute;
• Power power unit– 230 horses;
• Speed ​​while traveling on the highway – 85 kilometers per hour;
• Load moment – ​​40 t*m;
• LSHV - 9.85x2.50x3.65 meters.

Cargo height capabilities

Basically, the lifting capacity of the KS-3577 truck crane is determined by the reach of the boom equipment; here an inversely proportional relationship is observed. Working with and without outriggers also plays an important role. The use of supports with a boom length of about 10 meters and its reach of 5 meters makes it possible to achieve a load capacity of 8.5 tons. With similar parameters, but in the case of operation without supports, the load capacity drops to 1.4 tons.

General design of crane installations

Most often, Ivanovets and Klintsy cranes were installed on MAZ chassis, less often - Mashek and SMK models.

These cranes have rotating crane operator cabins, a telescopic boom (3-4 sections) with a hydraulic drive, which is powered by a vehicle chassis engine.

Extension of boom sections is carried out using a hydraulic cylinder and pulley blocks.

Cranes on the MAZ-5337 chassis are compact, the lifting height of the load is up to 25 m (with an additional jib).

Microprocessor load limiter ONK-160S with digital indication of crane loading parameters, boom radius and length, boom lift height and other data are displayed on the display. The actual size of the load on the hook and the possible lifting capacity for a given boom reach are also monitored.

In cramped conditions, you can automatically set the boundaries of the truck crane’s operating area. The “black box” (telemetric memory in the computer unit) records all operating characteristics and load during the operation of the crane.

The cost of renting a MAZ-5337 truck crane is 800-1500 rubles/hour.

All MAZ-5337 cranes are distinguished by good cargo-height characteristics and reliability of the main components.

Cranes in the photo

The section contains photos of different models based on the MAZ-5337.

The KS-3577 mobile crane, based on a 2-axle cargo chassis produced by the Minsk Automobile Plant, has been produced since 1984. The assembly is carried out at the production facilities of the truck crane plant located in the city of Ivanovo.

Device and purpose

The MAZ-5334 base chassis is equipped with a YaMZ-236 engine with a power of 180 hp. With. The car uses a 5-speed manual transmission. The rear axle is equipped with additional planetary gearboxes located in the wheel hubs. Due to this solution, it was possible to reduce the dimensions of the axle gearbox and expand the capabilities of the chassis.

To accommodate the crane installation components, a supporting platform is used, mounted on the rear of the chassis. The platform frame is welded from steel profiles of various sections. A turntable is installed on top, on which the crane boom is located, auxiliary equipment, cabin and counterweights.

To drive the winches and the rotation gearbox, a distribution module is used, which ensures reverse operation of the units. The winches and gearbox are driven by hydraulic motors. The boom angle is adjusted using hydraulic cylinders equipped with a hydraulic locking device. Hydraulics are used to change the length of the boom. Some crane models are equipped with a 3-section boom with a mechanical drive for extending the outer section.

The winch is equipped with a 2-speed gearbox. The unit is braked by a band brake equipped with a hydraulic release. A similar unit is used in the drive of the turning mechanism. If the hydraulics fail, the crane tower can be rotated manually using a special handle.

The hydraulic units of the crane are driven by a gear oil pump. The pump receives rotation from a cardan shaft attached to the output of the power take-off. The selection is carried out from the gearbox. The selection is activated by a separate lever located in the chassis cab. The supply of fluid required for hydraulic operation is located in a separate tank. All nodes of the system are connected by rigid or flexible highways.

The use of a sectional boom allows the machine to be used for loading or construction work in cramped conditions.

The telescopic boom provides equipment with the ability to maneuver in narrow passages between warehouses or buildings under construction.

The operator's workplace is located in a separate cabin. The instrument panel is equipped with indicators of the position of working parts and an alarm. The cabin is equipped with a ventilation unit with the ability to supply warm air. Next to the cabin there are crane mechanisms covered with a protective metal casing.

Specifications

The engine of the KS-3577 truck crane and the technical characteristics of the hydraulics provide a load landing speed of up to 10 m/min. The design of the extended boom with a jib allows for the lowering of loads weighing up to 4500 kg at speeds up to 20 m/min. During operation, the crane rests on adjustable outriggers equipped with hydraulic cylinders. The supports are located at the corners of the crane superstructure.

An important characteristic of the KS-3577 truck crane is the maximum lifting height of 14.5 m. The use of an extension element (jib) allows loading loads to a height of 20.5 m. The jib is a lattice metal section that is attached to the end of the boom. This extension is transported on the boom in a 180° position.

The technical characteristics of the KS-3577-3 crane differ from the base model in its lifting capacity, which is 14 tons. The increase in tonnage was achieved by increasing the size of the outriggers.

The KS-3577-2 modification is distinguished by the use of a MAZ-5337 chassis, equipped with a diesel engine with a turbocharger, as a base. Increased to 230 hp. power allows to reduce fuel consumption and provides increased speed of equipment up to 85 km/h.

The KS-3577-4 truck crane is equipped with special load grippers (instead of standard hooks on other modifications). Other machine parameters remained unchanged.

The KS-3577-3K Uglich machine has excellent parameters determined by its use as a base truck KamAZ-43253. The lifting capacity is 16 tons. The lifting system uses a microprocessor module that controls the boom operating parameters and reduces the risk of emergency situations. The module automatically calculates the permissible load weight depending on the reach and angle of the boom. Operating parameters are recorded in a non-volatile metering unit.

Advantages and disadvantages

Equipment owners note positive features:

• ease of operation;
• machine maneuverability;
• ease of maintenance of the crane hydraulic system;

KS 3577 is a multi-purpose truck crane, developed jointly with Russian and Belarusian engineers. It has high performance in all areas of activity - in the agricultural and construction fields, as well as in rescue operations. Everything in this model is balanced and convenient. A decent level of ergonomics, good maneuverability and maintainability, a wide dealer network, inexpensive spare parts and a large number of functions, moving parts and systems - all this makes the truck crane multi-purpose and universal in use. These advantages will be appreciated by professional users who need stability, reliability and comfort during long hours of use. The equipment is made mostly from domestic and Belarusian parts, but some components are borrowed from foreign partners. Due to this, the manufacturer and its customers only benefited, because the truck crane became more salable, durable and functional. Description and purpose buildings, structures, as well as moving bulky technical devices in vertical and horizontal positions. At the same time, there are no restrictions on the weight and dimensions of transported objects, because the equipment is designed for a maximum load capacity of 16 tons, which fully corresponds to the small class. By today's standards, this model looks decent against the background of current cars with an indicator of 25 tons. This truck crane has proven itself in logistics centers - where there is an urgent need to replace manipulators that lack power. KS 3577 is also designed for unloading, dismantling and removing rubble in the hottest spots with the participation of the Russian Ministry of Emergency Situations.

Features of the device and operation

KS 3577 is a specialized light-class loading mechanism mounted on a biaxial chassis of a Belarusian truck of the same name. The equipment is adapted for moving any heavy loads, including reinforced concrete products, metal constructions timber and other large objects. The truck crane is equipped with a trapezoidal support contour, due to which the already considerable lifting capacity for this class was increased.

The rotation of the rotary mechanism is carried out due to hydraulic drive, which works due to the torque generated by the car power plant. In this case, the torque enters the drive through a manual gearbox and is regulated by the power take-off. The pump can be manually turned on or off using a lever located in the driver's cab.

The telescopic two-section boom is an integral element of the crane installation. One boom is a fixed type, and the second is a movable one. The last (movable) boom extends to a height of up to 6 m using two hydraulic cylinders connected to each other by couplings. To increase the under-boom space and the lifting height of the hook suspension, the design includes a so-called lattice jib, which allows you to lengthen the height of the boom, and thereby expand the working area. The jib is in addition to the main boom and can be transported on a crane. For safety purposes, during transportation the jib is secured with a special clamp near the boom. For more convenient and quick extension of the jib, a lattice insert with brackets is provided, with the help of which the boom is connected to the jib. The boom mechanism is designed in such a way as to be able to move the load not only in the horizontal, but also in the vertical plane.

The cargo winch is another integral component of the KS 3577 crane installation. It includes a hydraulic motor, a two-stage cylinder-type gearbox, a drum, and a drum-type band brake with a hydraulic contactor. For a more reliable connection of the turntable with the frame, a single-row roller slewing ring with internal clutch is used.

The multifunctional operator’s cabin, installed on the rotating platform of the crane installation, deserves special attention. The inside of the driver's area is decorated with decorative plastic material with a vibration-isolating effect. The list of basic equipment includes windshield wipers, outward-opening windows, a ventilation system, an auxiliary heater, a lamp, sun visors, and full-size first aid kits and documentation.

It is noteworthy that a voltage of 24 V is sufficient to power all electronic equipment of the truck crane. The equipment is presented in the form of alarms and lighting, as well as safety devices and measuring sensors. Information from these sensors is processed in the central processor and then digitally displayed on the central display located in the operator's cab. The devices monitor the relay box, alarm panel, boom load and lifting capacity. In the event of an abnormality (for example, when the permissible load is exceeded, a drop in oil pressure or overheating, or when it comes into contact with a power line), a safety system is activated that prevents damage to the crane or the operator.

Prices

The average cost of a KS-3577 truck crane on the Russian market is less than a million rubles.
