133KW Cummins Diesel Engine Heavy Construction Vehicles SC230.8 With Closed Cab
Engine:
SC230.8 excavator is equipped with Cummins engine of Euro II Emission, which features 133/2000 output power and strong power, which is the largest among the models of the same weight; With the engine intake pre-filter, the daily maintenance time of the air filter is reduced, which can save the energy and care the environment. The outside oil filter element can be maintained easier.
Cab:
With new cab and sealing absorbent material, the noise of the cab is reduced; 24V voltage output is preserved in power connectors of the cab, cab door has the function of lubrication; the cab adopts new seat, new rail box and safety lock, and the wiring harness adopts waterproof connector, which improves the operation comfortability, reliability of the operator.
New monitor:
Based on the original operation modes, new monitor adds 4 economic E modes, which satisfies the requirements of the customers to save the fuel and reduces the volume as it is equipped in the front control box. The front operation room of the cab is enlarged. CPU features human intelligence and automatic diagnose function. If the engine is idling for more than 5 minutes, the monitor will notice the operator that the engine shall be turned off, in order to save the fuel.
Air conditioner:
With the electronic and automatic temperature control air conditioner, the temperature can be set between 18℃(63℉) and 32℃(91℉). The function of intake air filtering is added, in order to prevent the dust from entering the air conditioner; the amound of the discharged wind is increased, and the cooling and heating effect is improved. The filter element of the air conditioner can be disassembled easily to clean.
Working device:
Boom joint selects wholly casting structure, and the strength is improved, and the working device is reinforced, and the tensioning device is improved.
Safety improvement:
The standard device of GPS satellite positioning provides feedback all the time; new anti-skid plate with protrusion to increase the safety; With the safety rail on the machine supper structure, and rear view glass, the operator has excellent visibility for the rear part of the excavator.
