If you are considering purchasing a guide rail type cargo elevator, take a look at the purchasing guide provided by Shanghai Niuli Machinery.

一、负载能力：需要确定货梯需要承载的重量。这将有助于您选择正确的载重能力。在购买导轨式升降货梯时，通常会有多个载重能力可供选择。

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：选择正确的尺寸也非常重要。您需要测量货物的大小和形状，以确保货梯的平台大小和高度能够适应您的需求。一般来说，货梯的平台应该比货物尺寸大，以确保货物可以地升降。

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：性是选购货梯时重要的考虑因素之一。在购买货梯时，您需要确保它符合所有相关的标准。货梯应该具备多种防护装置，如保护门、闸等，以防止货物或人员在运输过程中受到伤害。在公司运作中也需要考虑货梯使用规范和操作培训。

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、售后服务：需要考虑货梯供应商的售后服务。如果您遇到货梯故障或需要维修，供应商应该能够及时响应并提供相应的支持。

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.
