• The travel assembly purchased from NABTESCO can offer strong power and good self-cleaning performance. It is fitted with heavy duty lengthened chassis and sloping track frame.
• Our crawler excavator is equipped with automatic idle system. When servo-valve stays in the neutral position for more than 5 seconds, CPU controller will stimulate stepping motor to reduce the swing speed to 1300rpm so as to reduce fuel consumption and noise.
• The crawler excavating machinery can also be fitted with quartering hammer and concentrate lubricating system, if required.
• SW210LC-5, SW230LC-5, and SW330Es crawler excavators differ from each other in traveling speed, swing speed, maximum vertical digging depth, maximum working radius and bucket capacity, etc. For example, the traveling speed of SW210LC-5 excavator is 5.4/3.1 km/h, of SW230LC-5 excavator is 5.5/3.5 km/h, of SW330Es excavator is 5.4/3.1 km/h. For more details, please refer to the parameter table.
