Vehicle appearance: dynamic, passionate

In today's world of visual effects, it has become a natural law for products to attract the public's attention with gorgeous shapes, and the aesthetic design of craftsmanship has penetrated into all corners of the appearance. A good product must be worth the money, taking the Sany SSC1020C special crane in front of you as an example, it seems that it has inherited the style of the Sany family inside and out: dynamic, young and passionate.

The shape of the Sany SSC1020C special crane not only takes a stable route, but also has obvious movement lines. Judging from the painting, the main colors of red, yellow and black are used in the SSC1020C, supplemented by white filled LOGO and model text, and the silver gray of a total of 16 wheels on the left and right gives people a new impression. It can be said that SSC1020C has conquered the eyeballs of countless people from the visual effect of *5656 eyes.

Cab: abundant and material

If the shape of the SSC1020 is refreshing to us, its cab interior decoration also has a unique atmosphere, the interior design is full of science and technology, and the function is also very material. The whole machine accessories of the SSC1020 are matched with the *5660 brand, the electronic control system on the car is very complex, and there are many items for hoisting and testing, which has always been the advantage of Sany equipment.

Sany SSC1020 special crane has two cabs, the getting off cab is similar to the car cab, the difference is that it is more spacious than the general car cab, and there is a fan-shaped control panel in the right-hand direction. It is used to control the suspension system and steering mode of the crane, which allows the driver to easily and quickly adjust the suspension and steering mode, so as to achieve rapid transfer of the vehicle and safe driving. In addition, the cab is equipped with a reversing camera system, which can effectively avoid accidents when reversing.

The cab of the SC1020 is divided into several sections, and the first thing that catches the eye is the driver's favorite adjustable suspension seat, which can be adjusted to suit his weight when using it. Sitting on the seat, the driver can see three high-definition LCD screens, and the left display shows the operating status of the crane winch. The display screen in the middle can display various data information of the crane, including working radius, lifting weight, angle, outrigger status, ambient wind speed and other items related to hoisting. The monitor on the right side is mounted on the boom, and the lifting of the equipment can be observed from top to bottom. Based on this data, the driver can adjust the crane in time to achieve safe and efficient lifting. At the same time, drivers can make personalized settings according to their own usage habits and different use conditions.

The front end of the seat armrest is similar to the pilot control handle on the excavator, which can achieve precise control, especially suitable for small adjustments in the hoisting wind power operation, and improve the efficiency of the latter link of the hoisting operation*. There is a control panel on the right side of the seat, and there are 20 buttons on and below respectively, which respectively control the functions of super lifting plate, disassembly and loading vehicle, arm pin, cantilever swing, cab swing, hoisting forced unlocking, aviation lights, winch mechanism, etc., which are good tools for crane drivers to complete their lifting work.

In addition, the SSC1020 cab can be adjusted to tilt up and left and right, so that the driver can see the hoisting situation in different positions, which is much stronger than the traditional crane cab in terms of visual range.

8-axle chassis structure: compact design

Sany SSC1020C special crane weighs nearly 100 tons, and the whole vehicle adopts 8 axles and 6+4 section arm design, which is not an exaggeration for us to call it a behemoth. The crane is equipped with a 480kW Mercedes-Benz V8 engine, which provides great traction and surging power for high-speed driving and climbing. It adopts the front four-axle mechanical steering auxiliary hydraulic assistance, and is equipped with the rear four-axle electro-hydraulic auxiliary steering system (the seventh and eighth axles can be connected to the car to achieve auxiliary drive), with a small steering radius and good maneuverability. The chassis drive capacity of the SSC1020C will naturally not become a concern for steering, and in the case of nearly 20m in the whole car, the small turning radius can not be more than 14m, it has to be said that it is a miracle, and it is fully applicable to the current domestic II., III. mountain wind field, narrow road width, large slope construction environment.

In addition, the chassis of the SSC1020 special crane adopts the latest oil and gas suspension and single-bar bolt technology, the chassis is strong, the driving ability is high, the climbing ability is strong, and it is equipped with an emergency steering system, which can effectively improve safety, and has 6 different steering modes, which can easily adapt to a variety of driving conditions. Includes: Highway Mode, All-Wheel Steering Mode, Crab Mode, Yaw-Free Steering Mode, Independent Rear Axle Steering Mode, Rear Axle Lock Mode. This six-mode steering system can not only make the SSC1020's small turning radius not more than 14m, but also smooth and reliable when driving at high speeds, and can even drive diagonally. It is worth mentioning that the vehicle of Sany SSC1020C * 5661 can reach a speed of 75km/h and a climbing degree of 30%, with reliable driving performance.

The working range is small, and the hoisting force is infinite

The 6+4 section crane of Sany SSC1020C special crane has a full extension height of 105.2 meters, and can lift 105t under the working range of 14m, with superior operating performance, and can easily complete the lifting and installation of 2.0MW wind turbines.

SSC1020C special crane adopts the structure of 6 columns + 4 booms, which is different from the traditional truss structure, and it adopts a new over-lifting structure form according to the needs of the structure, which improves the stress of the vehicle structure. SSC1020C by changing the wire rope pretensioning method to the pretensioning method of the cylinder pull plate, the use of wire rope of the winch mechanism can be greatly reduced, and the vehicle layout is greatly simplified from the structural form and control mode. Due to the reduction of the winch wire rope, the user's cost has been greatly controlled. At the same time, the upper and lower cantilever connecting the super lifting plate is in a closed state during transportation, and when the site is ready for construction, the width of these two sets of devices can reach more than 6m, and the lateral stability of the whole vehicle is optimized. It is reported that the new overlifting device optimizes the structural stress mode, improves the vehicle force stiffness during operation, improves the column stress, reduces the column deformation, significantly improves the lifting performance, and also solves the problem of long SSC1020 column and large force.

Vehicle on-site transfer technology: time-saving and fast

Due to the wind turbine with a capacity of 2MW and above, the nacelle can weigh up to 80t, and the lifting height needs to be greater than 80m, which makes the wheeled crane below 600t unable to be constructed, and the 600t wheeled crane needs to be equipped with a tower boom (working condition) for construction. When the 600t wheeled crane is constructed, it is necessary to disassemble and install the tower arm, the over-lifting wire rope and the main hook at each installation position, which greatly consumes the construction time and causes the hoisting efficiency to be very low.

Sany SSC1020C fundamentally solves the above problems through structural optimization. When it is transferred inside the construction site, it is only necessary to disassemble the counterweight (5 blocks with a total of 75t). With the skilled cooperation of the construction personnel, it only takes 4 and a half hours for SSC1020C to enter the construction state from the collection of one machine station to the next installation station. In addition, when encountering long-distance transfers, SSC1020C special cranes need to add dismantling booms, outriggers, winches and other accessories, and the disassembly and assembly time of all parts can be completed in less than 7 hours.

Safety first: Multiple measures to ensure safe operation

In terms of braking, Sany SSC1020C special crane adopts a dual-circuit braking system, which has a short braking distance and safer braking. At the same time, a variety of braking modes make braking performance more reliable. The pneumatic butterfly brake not only makes the brake pad replacement easier and faster, the service life is longer, but also the braking force is more powerful and the braking effect is better, making the crane transition safer and more efficient.

In terms of hoisting operations, the SSC1020C is equipped with a high-precision, high-stability and high-intelligence torque limiter system to ensure all-round hoisting operations and ensure that hoisting operations are more accurate, stable and safer. In addition, the SSC1020 also adopts the original single-cylinder bolt telescopic boom technology, and the cylinder arm pin interlock combines mechanical, electrical and hydraulic triple protection, which is more reliable and safe.

The main winch mechanism of Sany SSC1020C special crane adopts an open winch system, which has the characteristics of high efficiency and low energy loss, and its winch has good micro-motion and stability. At the same time, the equipment is also equipped with a four-level protection system to ensure that the winch system is safer, more efficient and more reliable.

All-terrain cranesWith the advantages of rapid transfer and long-distance driving, it has become the preferred construction equipment for wind power hoisting construction, and the single-SSC1020C special crane has a combination of 59m six-section column + 46.2m four-section crane boom, an original quasi-over-lifting rear pull plate structure, and a lifting height of 105m, a working range of 14m and a lifting weight of 105t, which can directly lift part of the 2.5MW nacelle. We have reason to believe that Sany SSC1020C special crane will make a strong mark on the white paper of China's hoisting industry.
