SCC2800A Sany crane - load chart, specs & dimensions (2020 - 2026)

Cab and Control

Novel operator's cab with fashionable profile, nice interior and large window glass, which can tilt up by 20° to provide a panorama view. There are low and high-beam lights, a back-view mirror, heater and A/C, radio, and other functions. The layout of the seat, handles, and control buttons are designed with ergonomic principles to make operation more comfortable. The cab layout includes an integrated 10.4-inch touch screen, two monitors, a standard vibration handle, and a man-machine interaction interface that are all improved. The armrest box on the left and right armrest contains control handles, electrical switches, an emergency stop, and an ignition switch. The armrest box can be adjusted along with the seat. The seat features a multi-way and multi-level floating adjustable design with an unload switch. The A/C provides both cool and heat air with optimized air channels and vents. Additionally, multiple cameras can be displayed on the monitor simultaneously to enable backing video, real-time monitoring of hook working, travel area, wind, and wire rope revolving conditions.

Lightning Protection Device

It is offered as an optional feature, which includes the grounding device that can effectively protect the electric system elements and workers from lightning.

Illuminating Light

The machine is equipped with low beam and high beam lights at the front of the cab, illumination lights inside the cab, and other night lights, including boom lights, to improve visibility during construction.

Rearview Mirror

The rearview mirror is separately set on the left front of the cab and on the handrail at the front of the right sheet metal, allowing the operator to monitor the rear part of the machine.

Seat Interlock

The function lock lever on the left side of the cab seat must be put down, or if the operator leaves the seat, all control levers will be deactivated to prevent any misoperation due to accidental collision.

Monitor System

The standard remote monitoring system provides functions such as GPS location, GPRS data transfer, machine operation status inquiry and statistics, operation data monitoring and analysis, and remote diagnosis of failures.

Travel drive

Independent travel drive device is used for each side of crawler. Straight line traveling and steering is driven by travel motor through reducer and drive wheel. An automatic machine direction switch is available. The travel system is configured with low and high speed options, which can travel as fast as 1.0 km/h. Gradeability: 30%.

Assembly/Work Mode Control Switch

Under the assembly mode, over-hoist limit switch, crane boom limit device and load moment limiter do not work, so as to facilitate the installation of crane. All safety limit devices work in the work mode.

Load Moment Limiter (LMI)

It is an independent computerized safety control system. LMI can automatically detect the load weight, work radius and boom angle, and present on the display the rated load, actual load, work radius and boom angle. In normal operation, the LMI can make a judgment and cut off automatically if the crane moves towards dangerous direction. It can also perform as a black box to record the lifting information. It is composed of monitor, angle sensor and force sensor and other parts.

Over-hoist Limit Switch of Main/Auxiliary Hooks

Over-hoist protection device comprises of limit switch and weight on boom top, which prevents the hook lifting up too much. When the hook lifts up to the limit height, the limit switch activates, the buzzer on the left control panel sends an alarm, the failure indicator light starts to flash, and the hook hoisting action is cut off automatically.

Over-release Limit Switch of Main/Auxiliary Hooks

It is comprised of activator in the drum and proximity switch to prevent over release of wire rope. When the rope is paid out close to the last three wraps, the limit switch acts, and the system sends an alarm through the buzzer and shows the alarm on the instrument panel, automatically cutting off the winch action.

Function Lock Lever

If the function lock lever is not in the work position, all the other handles won’t work, which prevents any mis-operation caused by accidental collision.

Boom Hoist Drum Lock

Pawl lock is used on the boom hoist winch, which needs to be unlocked by switch before operation, in order to prevent mis-operation of handles and ensure safety during non-work time.

Boom Limit Device

When the boom elevation angle reaches the max. set limit, the buzzer sounds and boom action is cut off. This protection is two-stage control ensured by both LML system and travel switch.

Tri-color Load Indicator

The load indication light has three colors: green, yellow, and red, and the real-time load status is presented on the display. When the actual load is smaller than 90% of rated load, the green light is on; When the actual load is larger than 90% and smaller than 100%, the yellow light is on, the alarm light flashes and sends out intermittent sirens; When the actual load reaches 100% of rated load, the red light is on, the alarm light flashes and sends out continuous sirens; When the actual load reaches 102% of rated load, the system will automatically cut off the crane operation in a dangerous trend.

Audio-visual Alarm

When the engine is working, the light flashes; when the machine is traveling or swinging, it sends out sirens.

Electronic Level Indicator

It displays the tipping angle of the crane on the monitor in real time, protecting the machine from dangerous situations.

Emergency Stop

In emergent situation, this button is pressed down to cut off the power supply of whole machine and all actions stop.

Engine Status Monitoring

The engine status will be presented, such as engine coolant temperature, fuel volume, total work hours, engine oil pressure, engine speed, battery charging, voltage.

Swing Mechanism

Swing brake adopts wet, spring loaded, normally-closed brake, and braking through spring force. Swing system adopts integrated swing buffer valve and free slipping function, making sure the start and control is steady, and providing excellent inching function. Unique swing buffer design makes the braking more stable. Swing drive: external engaged swing drive with 360° swing range, and the max. swing speed is 1.0r/min. The max. drive pressure can reach 20MPa. Swing lock: cylinder lock can ensure the upperworks locked securely at four directions after work or during transport. Swing ring: three-row roller bearing.

Boom/Jib/Hoist Mechanism

Including: boom hoist mechanisms, jib hoist mechanism, mechanism. Drums with folded-line grooves are adopted for all luffing devices. Hydraulic motor drives the planetary gear reducer to realize multiple composite actions and it is equipped with good inching performance.

Boom

The boom is a spatial lattice structure with equal section areas for inserts and tapered section areas for both ends. With tubes welded together, and boom tip and root strengthened with steel plates, it can better transfer the load;The length of the boom ranges from 20m base boom to the maximum length 86m;Composition: boom base 10m x1, transitional insert 6m x1, boom top 1m x1, boom insert 3m x1, boom insert 6m x1, boom insert 12m x5;Boom length varies from basic boom of 20m to max. length of 86m, increasing every 3m. The extension jib is mounted on the boom top.

Back-stop Device

The boom adopts back stop oil cylinder structure, the larger the compression is, the larger the back stop force. The maximum back-stop cylinder is 38t. There is a pair of mechanical back-stop device for luffing jib rear strut to prevent mast backing and tension rear strut pendant. When the boom to jib angle approaches the smallest angle, there is pneumatic back-stop device to prevent back tipping. The maximum back-stop force is 50t.

Boom Angle Indicator

Pendulum angle indicator is fixed on the side of boom base close to the cab, so as to provide convenience to the operator.
