Powerful and environmentally friendly: Equipped with an engine with a rated power of 50.7kW, it offers abundant power output. By adopting a high-pressure common rail fuel injection system and cooling exhaust gas recirculation technology, combined with diesel oxidation catalysts, it eliminates the need for DPF and DEF, reducing emissions while lowering maintenance costs.
High operational efficiency: The boom rises and swings at a fast speed, increasing productivity by 9% compared to the previous generation. During the P mode 90° unloading and loading operation, the efficiency is enhanced by 23%. Equipped with six working modes, it can be flexibly switched according to different operation requirements. The standard high-flow auxiliary hydraulic system and proportional control lever can achieve precise accessory control.
Adapt to narrow Spaces: With a compact short-tail design, the tail swing radius is only 1390mm. The front and rear angles of the superstructure are both circular, and the maximum extension of the cab on the tracks is only 9 inches, facilitating flexible operation in narrow areas such as urban environments, confined Spaces, and crowded construction sites.
