液压货梯http://www.jnliqiao.com/属于高空作业，输送物料的一种机械设备，液压货梯的种类繁多，而每一种液压货梯的组成也是不一样的，那就施工液压货梯来说，其液压货梯天轮的重要性是非常大的。
Hydraulic cargo lift belongs to high altitude operation, a mechanical device for conveying materials, type of hydraulic cargo lift is various, and the composition of each hydraulic cargo lift is not the same, then the construction of hydraulic cargo lift, the importance of hydraulic cargo elevator sheave is very big.

天轮是施工液压货梯安全的一个重要环节，液压货梯天轮又分为单笼升降机天轮与双笼升降机天轮，但是使用时一样的作用也是一样的天轮架是施工液压货梯重要承重装置，天轮是底笼的一个重力拉起点，其重力全都在天轮上承受，天轮是有导向滑轮和天轮架钢结构组成，支撑的是导向配重的钢丝绳。
The sheave is an important link in the construction of hydraulic elevator safety, hydraulic cargo elevator sheave is divided into single and double cage elevator cage elevator sheave sheave pulley frame, but use the same effect is the same as for construction of hydraulic cargo lift an important bearing device, a head sheave is a heavy at starting point bottom cage, the gravity of all at the wheel on the bear, sheave wheel is composed of a guide pulley and the pulley frame steel structure, support is the wire rope guide counterweight.

在天轮架的钢架构选择上一定要选上好的工字钢。安装时一定要校正不得有偏差，天轮部位虽小在液压货梯http://www.jnliqiao.com/上是起到关键导向配重的作用，因此大家在选择与安装天轮上一定要按标准的规定操作不可小视大意。
In the steel structure of the pulley frame choice must choose good i-beam. There shall be no deviation must be corrected when installing, small head sheave part in hydraulic cargo lift is to play a key role in guiding the counterweight, so everyone in the selection and installation of pulley must according to the provisions of the standard can not be careless operation.
