1、 Working principle: Hydraulic elevators mainly use the principle of using oil cylinders to push the lifting platform up or down using high-pressure oil. The elevator uses electric motor driven cables or hydraulic systems to move the elevator box up and down.

二、应用场合：液压升降机主要用于小范围的场合，如别墅、工厂、、酒店等地方进行货物和人员的垂直运输。而电梯则广泛应用于高层建筑、公共交通场所和商业中心等。并且电梯还可以具有多种功能，如监控、灭火、紧急救援等。

2、 Application: Hydraulic elevators are mainly used for vertical transportation of goods and personnel in small areas, such as villas, factories, shopping malls, hotels, and other places. Elevators are widely used in high-rise buildings, public transportation places, and commercial centers. And elevators can also have various functions, such as monitoring, firefighting, emergency rescue, etc.

三、功能特点：液压升降机的主要功能是升降货物和人员，很难满足多种需求。电梯更加灵活多变，可以根据不同场合和需求设置不同的功能，如开门关门速度、报警系统、风速等。

3、 Functional characteristics: The main function of hydraulic elevators is to lift goods and personnel, which is difficult to meet various needs. Elevators are more flexible and versatile, and different functions can be set according to different occasions and needs, such as door opening and closing speed, alarm system, wind speed, etc.

四、管理：液压升降机的性低于电梯，因为液压升降机没有类似于电梯的门、故障监测器等装置，一旦出现问题，会给人员和财产带来不小的危险。而电梯则具有完备的设备，可在故障发生时自动切断电源，保障人员和财产的。

4、 Safety management: The safety of hydraulic elevators is lower than that of elevators because they do not have safety devices such as safety doors and fault monitors similar to elevators. Once problems occur, they can pose significant risks to personnel and property. Elevators, on the other hand, have complete safety equipment that can automatically cut off the power supply in the event of a malfunction, ensuring the safety of personnel and property.

升降货梯的本体是由架子和平台组成的，架子由立柱和轨道构成。升降货梯的工作原理是通过电机驱动液压泵将油液通过液压缸作用于升降货梯架子上的活塞上，实现升降货物的目的。在进行货物升降操作的同时，驾驶员通过控制器控制升降货梯的上升和下降，以及停留在指定层数等动作。

The main body of the cargo elevator is composed of a frame and a platform, and the frame is composed of columns and tracks. The working principle of an elevator is to drive a hydraulic pump through a motor to apply oil through a hydraulic cylinder to the piston on the elevator frame, achieving the purpose of lifting and lowering goods. During the cargo lifting operation, the driver controls the lifting and lowering of the cargo elevator through the controller, as well as stops at a specified number of floors.

在使用升降货梯时，需要特别注意货物的重量和体积。因为升降货梯的承载能力和升降高度是有限制的，如果超重或超载，可能会导致货梯不平衡或升降不稳定，甚会造成货梯本体的损坏。因此，使用升降货梯的时候需要注意保证载物的重量和尺寸在规定范围内，并进行固定和加固，以确保运输。

When using a cargo elevator, special attention should be paid to the weight and volume of the goods. Because the carrying capacity and lifting height of the cargo elevator are limited, if overweight or overloaded, it may cause the cargo elevator to be unbalanced or unstable, and even cause damage to the cargo elevator body. Therefore, when using a cargo elevator, it is necessary to pay attention to ensuring that the weight and size of the load are within the specified range, and to fix and reinforce it to ensure transportation safety.
