Performance characteristics of YTQU55B

1. It adopts a high performance Cummins diesel engine with engine power of 175 kw. Due to the reasonably-matched power, it provides a reliable, economical and environment-friendly and high efficient power source.

2. The retractable chassis structure has an extended folding bracket to improve the stability of chassis and at the same time not to influence overall transportation. The extension and retraction of crawler can be directly controlled in the cab, and the extension and retraction can be done simultaneously with the machine walking. Its width during transportation period reaches 3360 mm and its width during working period reaches 4520 mm, so the stability of whole vehicle is good. The seat hole has been earmarked for connecting casing oscillator.

3. The rotary table of the upper part, with high structural strength, adopts modular design and has a independent installation place reserve for hydraulic oil radiator. Standard connecting seats for pile frame are provided in front of the left and right platforms.

4. The M7 level main winch has a free lowering function, with maximum pulling force of single rope of above 10 tons and the fastest rope speed of 110m/min. With high working level and strong lifting ability, the main winch can greatly improve working efficiency and is suitable for a variety of devices. The external caliper brake used during free lowering, with big braking force and durable friction plate, is easy to replace. The cab is equipped with main winch multi-control switch, which is convenient for main winch and assistant winch to work simultaneously.

5. The derricking winch mechanism which is equipped with ratchet locking device guarantees the safe and reliable positioning of boom.

As a specialized supplier of construction machinery of PLA Construction Engineering Corps, Yutong Heavy Industries has made outstanding contributions to the national defense construction, supplied thousands of various equipment like high-speed bulldozers and loaders for this Corps, and been highly appraised by the army due to the high quality of its products in the past 60 years.
