A rail type cargo elevator is a device used to transport goods inside a building. It usually consists of a platform and side fixed guide rails, which can vertically lift and lower goods. If you are considering purchasing a guide rail type cargo elevator, take a look at the purchasing guide provided by Shanghai Niuli Machinery.

一、負載能力：需要確定貨梯需要承載的重量。這將有助于您選擇正確的載重能力。在購買導軌式升降貨梯時，通常會有多個載重能力可供選擇。

1、 Load capacity: It is necessary to determine the maximum weight that the cargo elevator needs to carry. This will help you choose the correct load capacity. When purchasing a rail type cargo elevator, there are usually multiple load capacities to choose from.

二、尺寸：選擇正確的尺寸也非常重要。您需要測量貨物的大小和形狀，以確保貨梯的平臺大小和高度能夠適應您的需求。一般來說，貨梯的平臺應該比貨物尺寸大，以確保貨物可以地升降。

2、 Size: Choosing the correct size is also very important. You need to measure the size and shape of the goods to ensure that the platform size and height of the cargo elevator can meet your needs. Generally speaking, the platform of a cargo elevator should be larger than the maximum cargo size to ensure that the cargo can be safely lifted and lowered.

三、性能：性是選購貨梯時重要的考慮因素之一。在購買貨梯時，您需要確保它符合所有相關的標準。貨梯應該具備多種防護裝置，如保護門、閘等，以防止貨物或人員在運輸過程中受到傷害。在公司運作中也需要考慮貨梯使用規(guī)范和操作培訓。

3、 Safety performance: Safety is one of the most important considerations when choosing a cargo elevator. When purchasing a goods elevator, you need to ensure that it meets all relevant safety standards. Freight elevators should have various protective devices, such as protective doors, safety gates, etc., to prevent damage to goods or personnel during transportation. In the operation of the company, it is also necessary to consider the use of cargo elevators and safety operation training.

四、售后服務：需要考慮貨梯供應商的售后服務。如果您遇到貨梯故障或需要維修，供應商應該能夠及時響應并提供相應的支持。

4、 After sales service: Finally, it is necessary to consider the after-sales service of the freight elevator supplier. If you encounter a cargo elevator malfunction or need repair, the supplier should be able to respond promptly and provide corresponding support.
