　　使用规则

　　OPERATION INSTRUCTIONS

　　使用前须对吊钩、起重链条、制动装置等机件及 润滑情况进行检查.认为完好无损后再使用。使用时 必须严守下面九条安全事项。

　　Before lifting, inspect carefully the hooks, the load chain, the brake device and lubrication of the block put it into operation

　　For safe operation, you must keep six rules as following.

　　1起吊重物不得超 过手拉葫芦的规定起重量。

　　Don' t lift any load excceeding the rated eapacity of the chain block

2不能用多台葫芦吊一个重物。
Don’t use more than one piece of chain block to lift one single load
 
3.不要拉得太局或放的太低。
Don’ t pull up too high or too down.

4、发现手拉链条拉不动时不可猛拉，更不 能增加人员，应立即停 止使用。

In case of the hand chain fails to move, don’ t pull it violenty or by increasing force. Stop operation and proceed inspectoon of the chain block.

5、起吊重量时，严禁人员在重物下做任何工作或行走。

To avoid accidents, working or passing under a lifting load is stricly forbiden.

6.链条弯曲或扭结时不可使用。

Don’t use, when the chain is kinking.

7. 不可横拉重物。 Don¹ t get the load dragged of the crossing.

　　8.不要抛摔葫芦。

　　No wild throwing or rough handling of chain blocks.

　　9.两股链条不能翻

　　转，不要扭曲。

　　No twising. No capsizing for two falls of chains.

　　维护方法

　　MAINTENANCE

　　©使用完毕后，应将葫芦上的泥垢擦净，存 放在干燥地点，防止受潮生锈和腐蚀。

　　@每年应由熟悉葫芦机构者，用煤油清洗机 件，在齿轮和轴承部分，加黄油润滑，防止 不懂葫芦性能原理者随意拆装。

　　@齿轮安装时，应使用两只片轮的“0”字 标记安装在同一直线上。

　　©起重链轮左右轴承的滚柱，可用黄油粘附 在已压装于起重链轮轴颈的轴承内圈上，再入 墙板的轴承外圈内。

　　©安装制动装置部分时，注意棘爪部啮合良 好，弹簧对棘爪的控制应灵活可靠。装上手链 轮后，顺时针旋转手链轮，应将棘轮、摩擦片压

　　紧在制动器座上，逆时针旋转手链轮.棘轮与摩擦片 间应留有空隙。

　　©支撑杆与右墙板为静配合，维修时切勿拆卸。

　　®葫芦经过清洗检修后.应进行空载和重载试验. 确认运正常，方可使用。

　　©在加油和使用过程中.制动装置的摩擦表面必须保 持干净，幷经常检查制动性能.防止制动失灵引起重物 自坠。

　　©为了维护和拆卸方便，手链条其中一节系幵□链 (不焊，涂色)。

　　Q After operation clean the chain block from dirt a门d keep it i门• a dry place from rust andcorrosion.

　　@ Clean the chain block annually by purging the

　　parts in kerosene and apply greas them.lt is advisable that the cleaning work should be one by skilled hands.

　　^ u0,f marks on the two disk gears should be aligned.

　　© Stick the rollers of both left and right bearings to the inner race of the bearings on the chain sprocket shaft journal, and then put them into the outter race of the bearings on the side plates.

　　@ While saambling the brakemechanism.care should be taken to mesh the slanting teeth of the ratchet discand the pawl. Make sure that the pawl is controlledby the spring sensitively and reliably.Then turn thehand wheel clockwise after screwing it onto the driving shaft, and it must press the disc and the plates on the brake seat. Turning it counterclockwise, there should be clearances between the disc and the plates.

　　@ The stay and the right side plate are in transition fit . Care should be taken not to dismantle them.

　　Q After cleaning and repair,the chain bloxk should be subjected to non-load and heavy load tests. If it works normally out it into operation

　　Keep clean the friction surface of the brake mechanism while lubricating or operating the chain block. Inspect the brake mechanism "frequently so as to avoid faulty braking of falling falling of load.

　　For conveniense of maintenance and dismantling, one of the links of the hand chain is open,painted in color and not welded.
