Performance characteristics of YTQU80
1. It adopts a high performance Cummins diesel engine, providing international warranty service. The
engine with  engine power of 260 kw meets the emission standard of GB II and can provide a reliable,
economical and environment-friendly power source.
2. The retractable chassis structure improves the stability of chassis and at the same time will not influence
overall transportation. The working width reaches 4900 mm, and the stability of whole vehicle is good.
3. The built-in planet gear reductor and high torque running motor have a large driving force, strong
gradeability and high reliability.
4. The main winch has a high speed free lowering function. Variable motor drive is used, which can not
only provide high speed, but also can greatly improve the working efficiency.
5. The lifting and derricking winch mechanisms which are equipped with ratchet locking device guarantee
the safe and reliable positioning of boom.
6. For the boom that is formed by welding of high strength structural pipe, the boom head adopts nylon
pulley which has a good stiffness, light weight, and high carrying capacity.
7. The pilot controlled and load sensing hydraulic control system has high micro-motion performance,
high accuracy,
and convenient and agile operating performance.
8. The swing mechanism that has a controllable free slipping mechanism can be controlled stably without
impact.
9. It is equipped with a reliable and high performance torque limiter to monitor the working condition
in real time. It is also equipped with safety devices such as rotary table swing locking device, boom
anti-overturn device, and winch over-rolling protection device to ensure the crane can work safely and
reliably.equipped with electric combination instrument, integrated control of engine data and automatic
alarm and is able to monitor engine's operating condition any time. It can also be equipped with optional
devices such as anemometer, level gauge and electric megaphone to conduct real-time indication and
monitoring of the working state and guarantee safe and smooth work.
11. The cab, mounted with shock absorption device, has wide view and beautiful appearance and is
equipped with high-grade damping seat, electric fan and heating equipment, greatly improving the
operation's comfortable degree. Video playing system, air-conditioning and voice broadcast system
are optional.
12. The largest single weight of the hanging-type counterweight is not more than 4 tons, so it is much
easier for installation, removal, and transfer.
