简介

brief introduction

液压启闭机，卷扬启闭机，门机，手轮式启闭机，手电式启闭机，手摇启闭机，螺杆式启闭机，双吊式启闭机等。

Hydraulic hoist, hoist and hoist, door machine, handwheel hoist, flashlight hoist, hand hoist, screw hoist, double hoist hoist and so on.

结构特点

Structural characteristics

1、启闭机包括电机、启闭机、机架、防护罩等组成；采用三级减速方式，用螺旋付传动，输出转距更大。启闭机配套钢架克服土建不平整，以减少整机噪声及振动。

1, the opening and closing machine includes the motor, the hoist, the rack, the protective cover and so on. It uses the three stage deceleration mode, with the spiral transmission, and the output turn distance is bigger. The supporting steel frame of the opening and closing machine overcomes the unevenness of the earth, so as to reduce the noise and vibration of the whole machine.

2、采用户外型长时工作制电机，防护等级≥IP55。行程控制机构采用十进制计数器原理，控制行程的误差0.5%。转距保护控制是通过蜗杆产生轴向位移触动微动开关，来达到保护电器的原理。

2, outdoor with long working motor, protection grade is greater than or equal to IP55. The travel control mechanism uses the decimal counter principle to control the error of the stroke of 0.5%. The distance protection control is the principle of protecting the electrical apparatus by generating the axial displacement of the micro switch by the worm.

3、操作维护简便，可实现现场和远控操作。

3, convenient operation and maintenance, can realize on-site and remote control operation.

操作规程

Operating procedures

1．工程施工单位，要将启闭机应安装在平整坚实、视野良好的地基之上，机身和地锚必须牢固。要求启闭机与导向滑轮中心线应垂直对正，启闭机距离滑轮一般应不小于十五米。

1. the construction unit should install the hoist on a flat and solid foundation with good vision, and the fuselage and anchor must be firm. The center line of the opening and closing machine and the guide pulley should be perpendicular to the right, and the distance of the pulley should not be less than fifteen meters.

2．在调装作业前，应检查钢丝绳、离合器、制动器、保险棘轮，传动滑轮等，确定安全可靠，方可操作。钢丝绳在卷筒上必须排列整齐，作业中最少需保留三圈。在作业时，不准有人跨越启闭机的钢丝绳经防止出现意外。

2. before the loading operation, the wire rope, the clutch, the brake, the insurance ratchet, the transmission pulley and so on should be checked, so that it is safe and reliable to operate. The wire rope must be arranged neatly on the reel. At least three rings should be kept in the operation. In the operation, no one is allowed to cross the wire rope of the open and close machine to prevent accidents.

3．在吊运重物需在空中停留时，除使用制动器外，并应用棘轮保险卡牢。操作时，严禁擅自离开岗位。

3. when the heavy lifting needs to stay in the air, the ratchet is applied in addition to the brake. At the time of operation, it is forbidden to leave the post without authorization.

4．工作中要听从指挥人员的信号，信号不明或可能引起事故时，应暂停操作，待弄清情况后方可继续作业。作业中突然停电，应立即拉开闸刀，并将运送物件放下。

4. should listen to the signal of the commander, when the signal is unknown or may cause the accident, the operation should be suspended, and the operation can be continued after the situation is clear. A sudden power outage during the operation, should immediately pull the knife, and transported down objects.

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.

技术参数

technical parameter

额定起重量

Rated starting 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

Lifting 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.
