| 摘要 |
The invention relates to a method of measuring bending of a personnel hoist boom, a personnel hoist, and a measurement system. The boom (3) of the personnel hoist (1) is provided with at least two angle sensors (8a, 8b) arranged at a distance (L) from one another. When the boom bends, an angle difference (KE) whose magnitude is proportional to the magnitude of the bending is generated between angle values (K1, K2) of the angle sensors.
