试验方法：
Test method:
1、启闭机操作人员必须掌握启闭机的结构、性能与操作方法，并有一定的机械知识，以确保机器的正常运转。
1. The operators of the hoist must master the structure, performance and operation methods of the hoist, and have certain mechanical knowledge to ensure the normal operation of the machine.
2、操作前，对起闭机进行全面检查，各部位润滑情况是否良好，螺栓有无松动。
2, before the operation, the full inspection of the crane, the lubrication of each part is good, bolts are loose.
3、当启闭机运转时，操作人员不得离开现场，发现问题立即停机。
3. When the opening and closing machine runs, the operator must not leave the scene and find the problem is stopped immediately.
4、对机器进行维修时，必须清除载荷。
4. When the machine is repaired, the load must be removed.
5、在使用时,需随时由注油孔注入润滑油，要经常保持足够的润滑油，螺杆要定期清除油垢，涂护新油，以防锈蚀。
5, in use, to inject lubricating oil from oil hole, keep enough oil, screw to regularly remove dirt, paint protection new oil to prevent rust.
额定起重量：
Rated weight:
额定起重量是指吊具或取物装置（如抓梁）所能起升的最大工作负荷。包括吊具的自重。单位为千克。
Rated weight is the maximum working load that can be lifted by a hoist or a device (such as a scratching beam). Including the weight of the sling. The unit is kilogram.
起升高度或扬程：
Lift height or lift:
吊具最低位置与最高位置的垂直距离，称为启闭机的高度或扬程。一般在数值上与卷筒的最大收放绳量或液压启闭机活塞最大行程相等。单位为米。
The vertical distance between the minimum position of a sling and the highest position is called the height or lift of the hoist. It is generally equal to the maximum number of reels and the maximum stroke of the piston of a hydraulic hoist. The unit is rice.
工作速度：
Speed of work:
1、起升速度是电动机在额定转速下或油泵在额定排油量下吊具的上升速度。单位为米/分。
1, the lifting speed is the rising speed of the motor at the rated speed or the oil pump under the rated oil discharge. The unit is rice per cent.
2、闭门速度是指快速闸门启闭机在电动机关闭或液压回路节流油阀在最大开度时，闸门靠自重下落的速度，单位米/分。
2, closed door speed refers to the speed of the quick gate hoist when the motor is closed or the throttle of the hydraulic circuit is throttle. When the oil valve is at the maximum opening, the speed of the gate falling on its own weight is per unit per meter.
3、运行速度是指移动式启闭机运行结构的电动机在额定转速时，大车或小车沿直线运行的速度，单位米/分。
3, the running speed refers to the speed of the motor running in a straight line at the rated speed of the operating structure of the mobile hoist at the rated speed.
4、回转速度是指回转结构电动机在额定转速时的运转速度，单位米/分。
4, rotary speed refers to the speed of rotating structure motor at rated speed, unit meter per minute.
跨度：
Span:
跨度是指移动式启闭机大车运行轨道中心之间的距离，即大车的轨距。单位为米。
The span refers to the distance between the center of the running track of a mobile hoist, that is, the gauge of a large car. The unit is rice.
起重机的工作级别：
The working level of the crane:
起重机的工作级别是指起重机的工作忙闲程度，即启闭机一年内总的运行时间。
The working level of the crane refers to the working idle degree of the crane, that is, the total operating time of the hoist in one year.
1、轻级工作制是指运行时间短，间歇时间长。如：闸门与拦污栅等。
1. Light grade working system refers to short running time and long interval time. Such as: the gates and trash rack etc..
2、中级工作制是指使用频繁的启闭机。如：船闸的人字门等。
2, intermediate working system refers to the use of frequent open and close machines. Such as: the miter gate of the lock.
