SCC750A Sany crane - load chart, specs & dimensions (2017 - 2023)

Operating Comfort

Fully-enclosed steel frame structure is adopted, and the front, side, and the top of the cab are installed with large high-strength tempered glass, which admits sufficient light. The operator’s cab is bright with ample space, providing a wider view and isolating noise in a better way. A multimode and multilevel adjustable suspension seat brings the most comfortable driving experience for the operator. The design of the air outlet of the air conditioner is more reasonable. A better man-machine interactive interface is realized through an integrated 8.4-inch touch screen and programmable key switch. The left console is mounted with a slewing/auxiliary load hoist winch hydraulic-controlled cross handle, control buttons, emergency stop, radio, and A/C panel; the right console is mounted with the main load hoist winch/boom hoist hydraulic-controlled cross handle, as well as ignition and engine throttle buttons. Walking pedal and walking joystick are arranged on the front side, making the total layout more human-friendly.

Track Pad

High-strength alloy cast steel track pad can prolong the service life. They are 800mm wide, and the total amount is 65pcs x 2.

Operating Equipment

All chords of the boom of operating equipment are high-strength steel tubes, and the boom/jib top sheaves are made of high-strength anti-wearing Nylon material protecting the wire rope. The hooks are installed with milled welded steel sheaves. The pendant adopts a quick hitch connector that is easy to assemble and is offered as an option.

Illuminating Light

The machine is equipped with a short-beam light in front of the machine, a front angle adjustable far-beam light, lamps in the operator's cab, and lighting devices for night operation, all of which increase visibility during work.

Rearview Mirror

It is installed on the left of the operator's cab and at the front handrail of the sheet metal for monitoring the rear part of the 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. Outrigger cylinders of lowerworks are offered as options.

Crawler Extension and Retraction

The crawlers can extend and retract via cylinders. During Work Mode, the crawlers must be extended, and be retracted during transport with crawlers on.

Extension Jib

The extension jib is a welded structure connected to the boom by pins, used for auxiliary hook. Extension jib length: 1.1 m.

Load Moment Indicator (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. Composition: monitor, angle sensor, force sensor and other parts.

Over-hoist Protection

Over-hoist protection device comprises limit switch and weight on boom top, which prevents the hook lifting up too much. When the hook is lifted 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 Protection

The over-release protection device 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 proximity switch acts, the system sends an alarm through the buzzer and shows the alarm on the monitor, automatically cutting off the winch action.

Boom Limit Device

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

Tri-color Load Indicator

The load indicator 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 the 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 intermittent sirens sound. When the actual load reaches 100% of the rated load, the red light is on, the alarm light flashes, and continuous sirens sound. At this moment, the system will automatically cut off the crane's dangerous operation.

Alarm Light

When the machine is powered on, the alarm light will work when the time comes, to warn people around.

Electronic Level Gauge

It displays the tipping angle of the crane on the monitor in real time and sends out an alarm to the operator automatically when the angle is out of limit.

Emergency Stop

In emergency situation, this button is pressed down to cut off the power supply of the 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 and voltage.

Closed Circuit Monitoring System

The optional camera monitoring system can show the wire rope reeving on each winch, surrounding behind counterweight and environment around the machine.

Monitoring System

Standard remote monitoring system: It can provide functions like GPS locating, GPRS data transfer, machine status inquiry and statistics, operating data monitoring and analysis, and remote diagnosis of failures.

Safety Device

Installation/working mode switching switch In Assembly Mode, certain safety devices are disabled to facilitate crane assembly. In Work Mode, all safety limiting devices activate to protect the operation.

Function Lock

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.

Boom Hoist Drum Lock

Boom hoist lock is designed to lock the drum when the boom doesn't need to move, in order to prevent mis-operation. The boom hoist pawl can open and close by control of handle, and when the handle return to neutral position, the pawl will lock the drum automatically to ensure the work safety of boom.

Back-stop Device

Its major components are nesting tubes and spring, in order to buffer the boom backlash and prevent further tipping back.

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.

Seat Interlock

If the operator leaves the seat, all control handles will be locked immediately to prevent any mis-operation due to accidental collision.
