Lifting equipment are special machines that are subject to special requirements in terms of their technical capabilities and ensuring the safety of the operating and operating personnel. This article will discuss a unit called the pneumatic wheel crane KS-4361 A. Such attention is riveted to it for a number of reasons, because its long-term service has shown how effective it is in the process of loading and unloading, construction, installation and some other types of work.
general information
KS-4361 A is not just a crane, but, in fact, a whole range of lifting devices created on pneumatic wheels, capable of working with a weight of up to 16 tons. The cranes of this series were produced until very recently, starting in the 1970s. At the same time, more than 16,000 units of this equipment were created over the entire period of production. As practice has shown, the machine has proven itself ideally both in temperate climates and in the most northern and harsh regions, where the ambient temperature sometimes drops below -60 degrees Celsius.
Existing modifications
The crane KS-4361A, the characteristics of which will be given below, is based on the models K-161 and K-161C, produced for the temperate and polar climatic zones.
KS-4361C is a model for the northern regions where the ambient temperature can reach -60 °C. The metal structures of this machine are made of low-alloy steel, and the tires and sealing elements are made of frost-resistant rubber.
KS-4361AT is a machine specially designed for operation in the tropical zone.
KS-4362 - diesel-electric crane.

A few words about the scheme of the machine
The characteristics of the KS-4361A crane will, of course, be incomplete if you do not provide a description of its device. At the heart of the unit is a welded metal frame with a pair of bridges, both of which are driven. The front axle is mounted on a balancing support, and this, in turn, allows you to increase the grip of the wheels with the underlying surface. The wheel alignment angle is changed by hydraulic cylinders. The rear axle is equipped with a rigid suspension. In the center of the frame is a two-speed manual gearbox. Torque is transmitted to the axles through cardan shafts. Axle gearboxes are equipped with both bevel and cylindrical gears.
Side frames KS-4361A are equipped with outriggers with screw jacks. The installation and folding of these units occurs through the use of the hydraulic system of the crane. In general, the supports can significantly increase the stability of the entire machine and its load capacity. On top of the frame there is a turntable with the main working units of the crane. The connection of the frame with the platform is carried out using a two-row ball shoulder strap with a ring gear.
Each of the crane bridges has differential devices that allow the right and left wheels to rotate at different angular speeds.
Power point
The crane KS-4361A is equipped with a four-cylinder diesel engine with a power of 75 horsepower. The name of the motor is SMD-14A. The crankshaft of the power plant is coupled through an elastic coupling with a turbotransformer, which, in turn, makes it possible in a certain range of operating speeds of the entire crane. The compressor of the pneumatic system is mounted independently of the motor. The transmission of torque occurs with the help of a V-belt transmission. The compressor is cooled by a special fan.
Detailing
Crane KS-4361A has gear and cam clutches equipped with a hydraulic drive. Lifting units are driven by a combined system that includes both pneumatics and hydraulics. Winches start their work due to pneumochamber clutches, the reverse drive works in the same way. Stopping the rotation of the drums and rigid fixation in a given position is possible due to the presence of band brakes.
A characteristic feature of the crane is that the boom drive drums, load hook and grab are mounted on the same shaft.
The electrical equipment of the lifting machine is used to provide external and internal lighting, turn on and off sound and light alarms, activate limit switches, start the engine, heat and ventilate.
Swivel mechanism
It should be noted that the rotary mechanism is powered by the same engine as the rest of the components and parts of the entire crane. Bevel gears are fixed on the reverse shaft, which, in turn, engages the gear wheel of the reverse rotation mechanism.
A ball bearing is mounted on top of the vertical shaft, perceiving a radial load, and on the bottom - thrust and spherical double-row ball bearings.
The rotation of the crane turntable occurs at the moment when the gear runs around the ring gear with internal gearing.
Operator Safety and Workplace
The crane operator's console is located directly in the crane cab. The user activates the necessary mechanisms with the help of levers and handles. To provide the required level of driver protection, the machine uses a boom lift limit switch, a load limiter and a boom reach indicator.
Subtleties of operation
Absolutely any KS-4361A crane, where it is not difficult for everyone to find the frame number, is a rather dangerous machine during use and transportation. Therefore, the unit must be transported by road using a towing tractor at a speed of no more than 20 km/h. In the process of towing on a crane, it is imperative to turn on a neutral gear, remove the cardan shaft on one of the bridges and turn off the turn cylinders. If the process of transportation of KS-4361A is planned by rail, then in this case the crane should be disassembled into separate large components and parts. To do this, the pneumatic running wheels are dismantled, the boom is certainly removed, disassembling it into sections. The transportation itself is carried out on a four-axle platform.
Within the boundaries of the construction site and for short distances (up to 50 kilometers), the crane can also move on its own, both with the boom in the transport position and with a fixed load. In this case, the driving speed should be no more than 3 km / h. The working boom is always located along the longitudinal axis of the machine.

Assessment of the residual life of the crane KS - 4361 A head. No. 000 reg. ,
The assessment of the residual life of the crane was carried out according to
RD7 and RD.
1. Introduction.
Resource of any crane is defined as the total estimated operating time of the hoisting machine from the beginning of its operation or from the resumption of its operation after repair until the transition to the limit state.
Residual resource - The estimated value of the operating time of the hoisting machine (from the moment of the survey) until the limit state of its base parts (bearing metal structures) is reached according to fatigue criteria.
For the examined crane, the basic parts are:
Arrow, elements of its fastening
Outriggers
Base frame
swing frame
We will evaluate the residual resource according to the state of the above-mentioned load-bearing metal structures of the crane.
Basic provisions.
The residual life is estimated depending on the type of damage according to the following criteria:
Fatigue
Corrosion

The crane KS-4361 is based on a special all-wheel drive wheeled chassis equipped with dual pneumatic tires. The production of equipment under the Yurginets trademark began in the 70s. The car is intended for performance of installation and loading works on the open areas, and also in warehouses. Production was carried out at factories in Yurga and Kamyshin.
It is allowed to work equipment with a grab with a capacity of up to 1.5 m³. The working body is installed on an arrow with a length of 10.5 or 15.5 m. The maximum load weight in the bucket is 3700 kg. It is possible to install tower-boom equipment with a construction height of 15 or 20 m. In this case, a controlled boom with a reach of 10.5 m is used on the machine. The listed equipment is not included in the standard delivery.
Technical and lifting characteristics
Overall dimensions of the crane KS-4361A and technical characteristics:
- length - 14500 mm;
- width (with removed supports) - 3150 mm;
- height (with the boom lowered to the transport position) - 3030 mm;
- installation weight - 23700 kg;
- turning radius - not less than 12 m;
- carrying capacity when installing supports - 16 tons;
- carrying capacity without additional supports - 9 t;
- hook lifting height - 4.0-8.8 m (depending on the departure);
- speed of lifting and lowering the load - up to 10 m / min;
- platform rotation frequency - 0.5-2.8 rpm.
Device
The crane is based on a welded frame equipped with 2 bridges. The front steer axle is mounted on an equalizer support, which improves wheel traction on rough roads. Changing the angle of installation of the wheels is carried out by power hydraulic cylinders. The rear axle has a rigid suspension. A 2-speed manual gearbox is mounted in the center of the frame. Cardan shafts are used to transmit torque to the axles. Axle reducers include cylindrical and bevel gears.
On the side beams of the frame there are outriggers equipped with screw jacks. Installation and cleaning of knots is carried out from hydraulics of the crane. The use of supports increases the stability of the machine and contributes to an increase in load capacity. A turntable is installed on the upper surface of the frame, on which all the working units of the machine are mounted. To connect the platform and the frame, a 2-row ball shoulder strap with a ring gear is used.
See » Technical characteristics of the automobile crane KS-2561
Pneumowheel crane KS 4361A is equipped with a diesel power plant, which includes a 75-horsepower atmospheric 4-cylinder unit SMD-14A. The crankshaft of the engine is connected by an elastic coupling with a turbo-transformer, which allows you to smoothly adjust the operating speeds of the machine. Separately from the engine, a pneumatic system compressor is installed. Torque is transmitted by means of a V-belt transmission. A fan is used to cool the compressor.
The transmission consists of cam and gear clutches equipped with a hydraulic drive. The nodes include mechanisms for rotation and movement, respectively. A combined system with a pneumatic and hydraulic drive is used to control the lifting units. The winches are switched on by pneumatic chamber clutches; a similar drive is mounted on a reversing drive. The stop and fixation of the drums are carried out by band brakes.
The standard lattice boom of the crane has a length of 10.5 m; it is possible to install additional extension cords with a size of 5 m (up to 3 pcs.). Additionally, a fixed jib is mounted, having a length of 6 m. When using a jib, the length of the boom is limited to 20 m. At the base of the boom there is a hinge assembly; a protective stop is installed to prevent tipping onto the platform.
The machine has a torque converter designed to drive the working mechanisms of the crane.
A design feature is the installation of boom drive drums, a cargo hook and grab equipment on a single shaft.
The operator is placed in a closed metal cabin. The mechanisms are controlled by levers and pedals.
On a separate order, there are cars with an insulated cab equipped with an autonomous heater. The pneumatic system is equipped with a water vapor separator. The northern version of the crane allows you to work at an air temperature of -60 ° C.
Transportation
Inside the construction site, the equipment moves independently, developing a speed of up to 15 km / h. It is allowed to move with the payload installed on the crane boom. In this case, the assembly is located parallel to the longitudinal axis of the machine; permissible speed does not exceed 3 km/h.
To deliver equipment to the place of work, the method of towing on a rigid hitch is used. Trucks are used as a tractor; the speed of the road train is 20 km/h. When rebasing, the gearbox is transferred to the neutral position, the hydraulic cylinders installed on the controlled axle are turned off. Additionally, the cardan shaft is removed, which serves to drive the front axle.
See » TOP-3 models of domestic erection cranes based on MKT tractors
Delivery over a long distance is carried out by rail. Before loading, the wheels are removed from the machine, the boom is disassembled into component sections. The upper part of the knot is laid on the lower one. Loading is carried out by a crane installation with a lifting capacity of at least 25 tons. If the machine kit includes additional boom elements, they are transported on another railway platform.
The functional crane equipment has a mixed control system - pneumatic and hydraulic type. Drums and shaft devices are set in active motion by pneumatic chamber couplings, and the crane can be forced to move in the other direction by a reversing mechanism. The speed of the crane is easily adjusted by means of a turbo-transformer. This functional element consumes energy from the hydraulics of the crane.
The running gear receives supports with screw jacks. On the site, a heavy vehicle moves freely with a load at a speed of up to three kilometers per hour. By rail, equipment can be transported on a platform. Before loading onto it, foremen must remove all wheels and separate the sections of the boom. They need to be laid from top to bottom. For loading, a crane is used, the lifting capacity of which is twenty-five tons.
If you need to transport KS-4361 or KS-4361A for a decent distance, you will need to use a tractor and a tow hitch, that is, drag it in tow. To do this, the gearbox is set in neutral, the driveshaft is removed, and the wheel turn cylinders are turned off. Traffic often develops at speeds up to twenty kilometers per hour. But when cornering, it is better to reduce it by about six to seven times.
