Electrical Control System
▪▪Self-developed SYIC-II integrated control system is adopted with higher integration, precise operation and reliable quality;
▪▪Control system consists of power system, engine system, main control system, LMI system, auxiliary system and safety
monitoring system. CAN BUS is used for data communication between controller, monitor and the engine;
▪▪Monitor: the working parameters and status are shown on the monitor, such as the engine speed, fuel volume, engine oil pressure, servo pressure, wind speed, engine working hours, LMI data, ground bearing pressure, control handle function, alarm information, failure self-diagnosis;
▪▪Remote Monitoring System: newly developed APP can collect equipment status at any time anywhere. Online functions such as smart maintenance reminder, failure alarm, construction data feeding, one-click service request, equipment health management are available, which makes the information more transparent and instant;
▪▪Remote Control System:This is offered as optional function, all main mechanisms and assisting cylinders can be controlled through remote control box as an optional feature. The monitor can show data of engine and LMI to ensure smarter, easier and safer operation.
Hydraulic System
▪▪Main pumps: open variable displacement piston pumps are adopted to provide oil supply for main actuators of main
machine;
▪▪Gear pump: one dual-gear pump for oil radiator motor and A/C motor control circuit;
▪▪Control: main pump adopts load sensitive control; winch motor adopts limitless adjustable piston motor of variable displacement. The operating components are electrical control handle, one dual-travel electrically-controlled pedal to control various actuators proportionally;
▪▪Way of cooling: air-cooled heat exchanger, fan core and multistage cooling;
▪▪Filter: large flow, high precision filter, with bypass valve and transmitter, which can remind the user to replace the filter element in time;
▪▪Max. pressure of system:
Main/aux. load hoist, boom/jib hoist, swing and travel system: 33Mpa;

Cab and Control
▪ Novel operator's cab with fashionable profile, nice interior and large window glass, which can tilt up by 20°to provide panorama view. There are low and high-beam lights, back-view mirror, heater and A/C, radio and other functions. The layout of seat, handles, control buttons are designed with ergonomic principles to make operation more comfortable;
▪ Cab layout: Integrated 10.4-inch touch screen, two monitors, standard vibration handle, and man-machine interaction interface are more improved;
▪ 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 hook working, travel area, winch and wire rope reeving conditions.
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;

▪▪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.
Fixed Jib
▪▪The fixed jib is a spatial lattice structure with equal section areas for inserts and tapered section areas for both ends. With tubes welded together, and jib tip and root strengthened with steel plates, it can better transfer the load;
▪▪Fixed jib length varies from 13m to 42m, increasing by every 6m;
▪▪Composition: jib top 6.5m, jib base 6.5m, jib insert 6m x1, 11.5m x2;
▪▪The fixed jib length available is 13m, 19m, 24.5m, 30.5m, 36m and 42m; which can be mounted on boom length from 29m to 62m.
Luffing Jib
▪▪The luffing jib is a spatial lattice structure with equal section areas for inserts and tapered section areas for both ends. With tubes welded together, and jib tip and root strengthened with steel plates, it can better transfer the load;
▪▪Luffing jib length varies from 21m to 63m, increasing by every 3m;
▪▪Composition: jib top 6m, jib base 6m, jib insert 3m x1, 6m x2, 12m x3;
