Heavy-Duty 280Ton Hydraulic Crawler Crane SCC2800A
Product Description
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, lifting conditions and boom angle.
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.
▪ Filter: Large flow, high precision filter, with bypass valve and transmitter, which can remind the user to replace the filter element in time.
▪ Way of cooling: Air-cooled heat exchanger, fan core and multistage cooling.
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 lock: Cylinder lock can ensure the upperworks locked securely at four directions after work or during transport.
▪ Swing ring: Three-row roller bearing.
Product Characteristics
▪ 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.
▪ 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×1, transitional insert 6m×1, boom top 1m×1, boom insert 3m×1, boom insert 6m×1, boom insert 12m×5.

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×1, 11.5m ×2.
▪ 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.
