The main advantages of Komatsu 56 excavators (such as PC56-7 models) are focused on flexibility, power performance and driving comfort: High flexibility The body weighs only 5.3 tons, and uses a combination of 400mm track plates and 1560mm gauge to ensure stability in soft ground and narrow spaces (such as residential tunnels). The rear end slewing radius is only 1650mm, which is suitable for turning operations in complex working conditions. Strong power performance Equipped with the S4D87E-1 turbocharged engine, the rated power is 34.6kW@2300rpm, an increase of 12% compared to the same model. The CLSS closed hydraulic system supports standard/P mode switching, the hydraulic response speed in P mode is increased by 25%, the single bucket cycle time is shortened to 3.2 seconds, and the frozen soil crushing operation is excellent. 1 Excellent driving comfort The cab has spacious space, good air conditioning and high air output, providing operators with a comfortable environment. However, some users reported that limited viewing in the lower right corner and low chassis may lead to insufficient passivity. Low maintenance cost The hydraulic oil replacement volume is only 9.7L, and the maintenance cost is reduced by 18%. After working for 12,000 hours, the failure rate of hydraulic system is less than 5%. The thickened chain rail link and five heavy wheels are designed to enhance durability. Maintenance must follow the five-step method.
