升降货梯稳定性系统分析

1、打开支撑腿，额定载荷300kg下最大工作高度8m时，侧向工作角度可以达到15度，正向最大角度也可以达到15度。若不打开支撑腿在额定载荷300kg下最大工作高度8m时，正向最大工作角度只能达到5度。
1, open the supporting leg, the maximum rated load of 300kg working height of 8m, the lateral working angle up to 15 degrees, the positive maximum angle can also be reached 15 degrees. When you do not turn on the supporting leg maximum working height of 8m at rated load of 300kg, the forward can only reach a maximum working angle of 5 degrees.
 
2、不管是侧向还是正向，未打开支撑腿工作状态是不稳定的，而打开支撑腿可以大大提高工作倾覆稳定性，实际工作中，条件允许的状态下，应尽可能打开支撑腿，若特殊情况未使用支撑腿，工作角度不能超过5度。
2, whether the lateral or forward, not open support legs working condition is unstable, and open support legs can greatly improve overturning stability, practical work, under conditions permitting state, should be as open support legs, If special circumstances supporting leg is not used, the working angle can not be more than 5 degrees.
 
3、实际使用必须考虑各种影响因素，包括环境、路面、叉杆摆动及支撑腿强度等因素。虽然计算中很多地方临界载荷已经超过额定载荷，但在使用时仍然必须满足在额定载荷范围内，这样才能保证工作安全。
3, the actual use must take into account various factors, including the environment, road forks swing and the supporting leg strength and other factors. Although in many places the critical load is calculated over the rated load, but still must meet when used within the rated load range, so as to ensure safety at work.
