A crane is a type of lifting machinery that is widely used in construction sites. Some novice drivers do not know what is meant by crane k when driving a crane? Huanghe technicians from Xinxiang Crane Rental Company will answer your questions in detail.
Q: What does crane k mean?
Answer: Crane (crane) "K" represents the series model of the crane. For example: cranes QY20B and QY130K indicate: Q stands for lifting, Y stands for hydraulic pressure, 220 and 130 stand for rated lifting capacity, respectively, where B and K stand for product series model. Generally, the number indicates the tonnage (rated lifting capacity) in the car crane model. For example, "QY50K" is a K series 50t truck crane. Others such as: uppercase pinyin "QAY" means all-terrain crane series, "QUY" stands for crawler crane series. "QY" is the model of truck crane series.
Crane safety devices:
(1) Lifting indicator (angle plate, also called weight limiter)
The angle indicator installed at the root of the boom near the driving position changes with the elevation of the boom and reflects the included angle of the boom to the ground. Knowing the elevation of the boom at different positions, according to the crane performance table and performance curve We can know the reference values such as the amplitude value, lifting weight and lifting height at a certain elevation angle.
(2) Over hoisting limiter (also called ultra-high limiter)
A safety device installed on the pulley block at the end of the boom to limit the lifting height of the hook head to prevent overhanging accidents. It guarantees that when the hook is lifted to the extreme position, it can automatically send an alarm signal or cut off the power source to stop lifting to prevent over-rolling.
(3) Torque limiter
The torque limiter is a safety device that automatically cuts off the lifting or amplitude power source when the load torque reaches the rated lifting torque and sends out a prohibitive alarm signal. It is a limiter to prevent crane instability caused by overload.
(4) Anti-arm bar reclining device and anti-back bar bracket
Anti-arm back device and anti-back bar support are safety devices that can no longer be lifted when the boom is raised to the maximum rated elevation angle. It prevents backward tilting when the boom angle is too large.
