SCC2500A 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. Cab layout: Integrated 10.4-inch touch screen, programmable smart switches, and man-machine interaction interface are more perfect. Armrest box: on the left and right armrest box are control handles, electrical switches, emergent stop, and ignition switch. The armrest box can be adjusted along with the seat. Seat: multi-way and multi-level floating adjustable seat with unload switch. A/C: cool and heat air; optimized air channels and vents. Multiple cameras can present on the monitor at the same time to realize backing video, real-time monitoring of wire rope on each winch, conditions behind the counterweight, and surrounding the machine.

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 the low beam light and high beam light at the front of the cab, illumination light at cab, and other night lights, boom lights to improve the visibility during construction.

Lowerworks

Independent travel driving units are adopted for each side of the crawler, to realize straight walking and turning driven by travel motor through gearbox and drive wheel.

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.

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 dangerous trend.

Audio-visual Alarm

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

Emergency Stop

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

Function Lock Lever

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

Monitoring and Safety Features

Rearview Mirror Separately set on the left front of the cab and on the handrail at the front of right sheet metal, so as to monitor the rear part of machine. Pharos Pharos is mounted on the top of boom/jib to indicate the height. Anemometer It is mounted on the top of boom/jib, and displayed on the monitor in the cab. Electronic Level Indicator It displays the tipping angle of crane on the monitor in real time, protecting the machine from dangerous situation; Put down the function lock lever on the left side of cab seat or if the operator leaves the seat, all control levers will be de-activated to prevent any mis-operation due to accidental collision. Engine Power Limit Load Adjustment and Stalling Protection The controller monitors the engine power to prevent engine getting stuck and stalling. 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.

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.

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 an activator in the drum and a 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.

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. The back-stop device comprises nesting tubes and a spring to buffer the boom backlash and prevent further tipping back. Additionally, the boom angle indicator, a pendulum angle indicator, is fixed on the side of the boom base close to the cab, providing convenience to the operator.
