The innovation of 8t electric wheel excavator is given as follows:
1, The novel machine drive scheme.
2, The integrated managements and control system in the excavator is developed independently to allocate energy reasonably and run efficiently.
3, The controls of variable speed of electric motor and variable displacement of hydraulic pump are used for excavator to improve the maximum operation ability.
4, A novel load sensing technology based on variable speed control is adopted to realize closed-loop feedback control of hydraulic system.
5, Automatic idle stop control technology.
6, The machine component condition monitors is employed to realize high reliability.
Characteristics of SOCMA wheel excavator with lithium battery:
1, High reliability, long service life, IP67 protection. Eight years of electric motor quality assurance. Battery depth charge and discharge are more than 4000 times.
2, Low energy consumption. No need of maintenance of the diesel engine. The cost of usage and the maintenance of the machine can be reduce more that 50%. The cost recovery period is short.
3, Zero emission, low noise, low vibration, good comfort and safer handling of precise movement.
4, The electro-hydraulic compound drive of the machine has strong power, strong explosive force and high efficiency.
5, Easy to operate, with automatic/manual mode.
6, Dual mode of charge is more convenient.Fast charge can be realized.
