SCC2000A Sany crane - load chart, specs & dimensions (2020 - 2026)

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.

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.

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.

Electronic Level Indicator

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

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.

Assembly/Work Mode Control Switch

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

Over-hoist Limit Switch of Main/Auxiliary Hooks

The over-hoist protection device comprises a limit switch and weight on the boom top, which prevents the hook from lifting too much. When the hook reaches 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

This switch consists of an activator in the drum and a proximity switch to prevent the 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 displays 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, preventing any mis-operation caused by accidental collision.

Boom Hoist Drum Lock

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

Boom Limit Device

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

Back-stop Device

Its major components are nesting tubes and a spring, which buffer the boom backlash and prevent further tipping back.

Boom Angle Indicator

The pendulum angle indicator is fixed on the side of the boom base close to the cab, providing convenience to the operator.

Seat Interlock

When the function lock lever is put down on the left side of the cab seat, or if the operator leaves the seat, all control levers will be deactivated to prevent any mis-operation due to accidental collision.
