ENGINEThe Cummins, 6BTA5.9-C170 direct injection and turbocharged engine gives sustained power and high torque rise that is required for the more tough jobs. |
 |
 |
UNDERCARRIAGEWith high stability and low ground pressure, the rigid and boxed frame undercarriage meet the requirement of all type of terrains, giving a dependable and longevity of service in all harsh conditions. |
 |
 |
SAFETY DEVICESFree Fall System When the button is engaged,the load free-falls and then immediately stops when the button is released. Automatic Boom Kick-Out This system will ensure you will never bend another boom. Anti Tipping System Prevents tipping by calculating the maximum load that can be lifted. Anti Two Block Sets a minimum distance between the top block and the hook block,preventing collisions between them. |
 |
 |
CONTROL SYSTEMHydraulic joystick operation provides simultaneous, precise control of the load and boom functions with one hand.single lever control for the counter weight in and out. CABIN Good visibility to work area and top of the boom with a sky window on the roof, ROPS can be installed as the optional equipment. |
