卷揚機（又叫絞車）是由人力或機械動力驅動卷筒、卷繞繩索來完成牽引工作的裝置。可以垂直提升、水平或傾斜拽引重物。卷揚機分為手動卷揚機和電動卷揚機兩種?，F在以電動卷揚機為主。電動卷揚機由電動機、聯軸節(jié)、制動器、齒輪箱和卷筒組成，共同安裝在機架上。對于起升高度和裝卸量大工作頻繁的情況，調速性能好，能令空鉤快速下降。對安裝就位或敏感的物料，能用較小速度。常見的卷揚機噸位有：0.3T卷揚機 0.5T卷揚機 1T卷揚機 1.5T卷揚機 2T卷揚機 3T卷揚機 5T卷揚機 6T卷揚機 8T卷揚機 10T卷揚機 15T卷揚機 20T卷揚機 25T卷揚機 30T卷揚機。
卷揚機可分為國標卷揚機、非標卷揚機。國標卷揚機指符合國家標準的卷揚機，非標卷揚機是指廠家自己定義標準的卷揚機）通常只有具有生產證的廠商才可以生產國標卷揚機，價格也比非標卷揚機貴一些。 特殊型號的卷揚機有：變頻卷揚機 、 雙筒卷揚機 、手剎杠桿式雙制動卷揚機、帶限位器卷揚機、電控防爆卷揚機、電控手剎離合卷揚機、大型雙筒雙制動卷揚機、大型外齒輪卷揚機、大型液壓式卷揚機、大型外齒輪帶排繩器卷揚機、雙曳引輪卷揚機、 大型液壓雙筒雙制動卷揚機、變頻帶限位器繩槽卷揚機。1、JK0.5-JK5單卷筒快速卷揚機 2、JK0.5-JK12.5單卷筒慢速卷揚機 3、JKL1.6-JKL5溜放型快速卷揚機 4、JML5、JML6、JML10溜放型打樁用卷揚機 5、2JK2-2JML10雙卷筒卷揚機 6、JT800、JT700型防爆提升卷揚機 7、JK0.3-JK15 電控卷揚機 8、非標卷揚機。其中Jk表示快速卷揚機，jm表示慢速卷揚機，jt表示防爆卷揚機，單卷筒表示一個卷筒容納鋼絲繩，雙卷筒表示兩個卷筒容納鋼絲繩。
卷揚機使用時的注意事項：
1、卷筒上的鋼絲繩應排列整齊，如發(fā)現重疊和斜繞時，應停機重新排列。嚴禁在轉動中用手、腳拉踩鋼絲繩。鋼絲繩不許完全放出，最少應保留三圈。 2、鋼絲繩不許打結、扭繞，在一個節(jié)距內斷線超過10%時，應予更換。 3、作業(yè)中，任何人不得跨越鋼絲繩，物體（物件）提升后，操作人員不得離開卷揚機。休息時物件或吊籠應降至地面。 4、作業(yè)中，司機、信號員要同吊起物保持良好的可見度，司機與信號員應密切配合，服從信號統(tǒng)一指揮。 5、作業(yè)中如遇停電情況，應切斷電源，將提升物降至地面。 6、工作中要聽從指揮人員的信號，信號不明或可能引起事故 時應暫停操作，待弄清情況后方可繼續(xù)作業(yè)。 7、作業(yè)中突然停電，應立即拉開閘刀，將運送物放下。8、作業(yè)完畢、應將料盤落地、關鎖電箱。 9 鋼絲繩在使用過程中與機械的磨損.自燃的腐蝕局部損害難免，應間隔時間段涂刷保護油。 10嚴禁超載使用。即超過最大承載噸數。 11使用過程中要注意不要出現打結.壓扁.電弧打傷.化學介質的侵蝕。 12不得直接吊裝高溫物體，對于有棱角的物體要加護板。13使用過程中應經常檢查所使用的鋼絲繩，達到報廢標準應立即報廢。
卷揚機鋼絲繩的報廢標準：
1 直徑減小直徑磨損超過百分之四十應報廢，不超百分之四十應降低系數使用。2 表面腐蝕；當整根鋼絲繩表面腐蝕達到肉眼顯而易見時，鋼絲繩就不能使用。3 結構破壞；鋼絲繩整股破斷應報廢，有斷絲的鋼絲繩應降低系數使用。4 超載；超載使用的鋼絲繩不得使用。
國家交通基礎設施、城市建設的規(guī)模越來越大，建筑工程中使用的卷揚機規(guī)模、功率隨之越來越大，牽引速度也越來越快，相應地卷揚機的關鍵傳動件卷筒開式齒輪副結構的尺寸越做越大，在大功率、高速度運轉情況下卷揚機的噪聲也越來越高，然而這是國家標準所不允許的。建筑卷揚機國家標準GB1955—2002規(guī)定合格的卷揚機噪聲限值為機外不得大于85dB(A)、操作者耳邊不得大于88dB(A)。當卷揚機牽引力較小、速度較低時其噪聲都遠低于標準限值，控制也容易；但當牽引速度較高、牽引力較大時要確保噪聲不超標，需從設計、工藝、材料、質檢等各個環(huán)節(jié)采取有效措施。
卷揚機噪聲來源有多種途徑，但本質上是撞擊和振動的結果，一般是由于齒輪嚙合質量差、運動不平穩(wěn)在運動中產生了瞬時加速度而造成的。 我公司一臺80kN快速可溜放液力控制卷揚機，鋼絲繩牽引速度為30m/min、電機功率55kW，機器噪聲一般在標準范圍以內，但偶而出現噪聲超標現象，少數機器不能通過出廠檢驗。在排除噪聲時感到無從下手，因機器制造所依據的圖樣、工藝流程相同，既然絕大多數產品合格，就應排除設計和工藝不合理因素。噪聲來源分析及控制主要是我們認為底盤的設計制造存在造成噪聲的可能：1底盤采用箱形結構，不是所有焊縫都進行連續(xù)焊接，各個底盤焊縫的長短、高低位置不同，底盤剛性存在較大個體差異，有的則產生共鳴效應，機器如有一點震動噪聲就被放大；2底盤由鋼板焊成，不具備吸震消聲功能，如果其固有頻率與齒輪嚙合頻率接近就可能造成個別機器因齒輪弱小震動引發(fā)較大共震，引起噪聲值上升。 我們針對上述可能性分別進行試驗，但通過三次實驗發(fā)現噪聲高低與底盤結構、剛度、頻率等因素呈弱相關，噪聲大小與運動件強相關，因此底盤設計構造、制造質量并不是噪聲超標的原因。
軸承間隙有人認為，既然噪聲是伴隨卷筒總成和傳動件，那么就可能由于卷筒滑動軸承間隙大而引起。我們對卷筒零件配合間隙進行選擇，保證軸承孔與主軸間隙符合圖紙要求，裝配后進行試驗。試驗時采用變頻電機調速，觀察速度對噪聲的影響。? 大量試驗結果表明，速度對噪聲影響是第一位的，卷筒轉速越高則噪聲值越大、機器震動越激烈；間隙在其次，主軸與軸套間隙越大則噪聲也越大；而底盤對噪聲影響最小。如果機器本來噪聲就很低，則速度高低、主軸間隙大小的變化都不會產生過大噪聲，由此表明噪聲超標也不是由軸承間隙大而引起的。
卷揚機的分類及其不同特性卷揚機包括建筑卷揚機,同軸卷揚機 主要產品有：JM電控慢速大噸位卷揚機、JM電控慢速卷揚機、JK電控高速卷揚機、 JKL手控快速溜放卷揚機、2JKL手控雙快溜放卷揚機、電控手控兩用卷揚機、JT調速卷揚機、KDJ微型卷揚機等，僅能在地上使用，可以通過修改用于船上。它以電動機為動力，經彈性聯軸節(jié)，三級封閉式齒輪減速箱，牙嵌式聯軸節(jié)驅動。卷揚機的卷筒，采用電磁制動。該產品通用性高、結構緊湊、體積小、重量輕、起重大、使用轉移方便，被廣泛應用于建筑、水利工程、林業(yè)、礦山、碼頭等的物料升降或平拖，還可作現代化電控自動作業(yè)線的配套設備。Jm系列為齒輪減速機傳動卷揚機。主要用于卷揚、拉卸、推、拖重物。如各種大中型砼、鋼結構及機械設備的安裝和拆卸。適用于建筑安裝公司、礦區(qū)、工廠的土木建筑及安裝工程。由人力或機械動力驅動卷筒、卷繞繩索來完成牽引工作的裝置。叫同軸卷揚機：（又叫微型卷揚機）電機與鋼絲繩在同一傳動軸上，輕便小巧，節(jié)省空間 （其噸位包括（200公斤、250公斤、300公斤、500公斤、750公斤、1000公斤等）卷揚機還分為慢速卷揚機：卷筒上的鋼絲繩額定速度約7~12m/min的卷揚機。快速卷揚機：卷筒上的鋼絲繩額定速度約30m/min的卷揚機。 電動卷揚機：由電動機作為動力，通過驅動裝置使卷筒回轉的卷揚機。調速卷揚機：速度控制可以調節(jié)的卷揚機手搖卷揚機：以人力作為動力，通過驅動裝置使卷筒回轉的卷揚機。大噸位非標卷揚機：主要用于卷揚、拉卸、推、拖重物。如各種大中型砼、鋼結構及機械設備的安裝和卷揚機的拆卸。其結構特點是鋼絲繩排列有序、有吊安裝可靠、適用于碼頭、橋梁、港口等路橋工程及大型廠礦安裝設備.就是一種利用外力（例如電動機）驅動他運轉，然后通過電磁制動器和抱死制動器控制其在無動力下不自由運轉，同時經過電動機的帶動減速后，驅動一個輪盤運轉，輪盤上可以卷鋼索或者其他東西。
通常提升高于30噸的卷揚機為大噸位卷揚機，生產大噸位的卷揚機技術在中國只有少數，目前最大噸位是65噸。主要細分為JK（快速），JM、JMW（慢速），JT（調速），JKL、2JKL手控快速等系列卷揚機，廣泛應用于工礦、冶金、起重、建筑、化工、路橋、水電安裝等起重行業(yè)。
外文原文
Winch ( also called winch ) is produced by human or mechanical power drive reel, winding rope traction device to complete the work. Can be vertical, horizontal or inclined dragging heavy. Winch manual winch electric winch and divided into two. Now mainly to electric hoist. Electric hoist is composed of a motor, coupling, brake, gear box and the reel is mounted on the frame component, common. For lifting height and handling a large amount of work situation frequently, good speed performance, can make the empty hook rapid decline. The installation or sensitive material, with a small speed. Common winch windlass windlass tonnage are: 0.3T 0.5T 1T 1.5T 2T 3T hoist hoist hoist hoist hoist hoist hoist 5T 6T 8T 10T 15T 20T 25T hoist hoist hoist hoist hoist 30T.
Winch can be divided into GB, non-standard windlass windlass. To meet the national standard GB windlass windlass, winch is a non-standard manufacturers define their own standard winch ) usually only with the production of card manufacturers can produce GB winch, the price more expensive non-standard winch. Special types of Winch: frequency conversion winch, double drum hoist, handbrake lever type double brake winch, windlass, with restrictor electric explosion-proof winch, electric parking brake clutch windlass, large binocular double brake winch, large outer gear winch, hydraulic winch, the large external gear belt rope guider winch, a traction wheel winch, hydraulic double cylinder double brake winch, frequency band limiter for hoist rope groove. In 1, JK0.5-JK5 single drum fast hoist 2, JK0.5-JK12.5 single drum winch 3, JKL1.6-JKL5 humping slow type fast hoist 4, JML5, JML6, JML10 rolling type pile hoist 5, 2JK2-2JML10 double drum winch 6, JT800, JT700 explosion-proof electric hoist hoisting machine 7, JK0.3-JK15 8, non-standard winch. Wherein Jk represents fast hoist, JM said slow winch, said JT explosion-proof hoist, single drum represents a spool receiving wire rope, double drum two reels accommodate wire rope.
Hoist the matters needing attention in using:
In 1, the reel of wire rope should be arranged regularly, such as found in overlapping and helical winding, should be down to rearrange. Is strictly prohibited in the rotation of the hand, foot pull on the rope. Wire rope not fully released, at least should be reserved for three laps. In 2, steel wire rope to tie, twisted, in a pitch period more than 10% should be replaced when broken. In 3, during the operation, no person shall span wire rope, objects (objects ) after upgrading, operating personnel shall not be allowed to leave the windlass. When resting, objects or cage should be lowered to the ground. In 4, during the operation, the driver, the signalman to lift objects with good visibility, the driver and the signaller should cooperate closely, obey the unified command signal. In 5, operation in case of power failure, the power should be cut off, will enhance the material falls to the ground. In 6, to obey the command staff of the signal, the signal is unknown or is likely to cause accidents should be suspended operation, to clarify the situation before it can continue to work. In 7, working in a sudden power failure, should immediately open the knife, will carry object down. In 8, the operation is completed, should be the tray landing, closing lock box. The 9 wire rope in use process and mechanical wear. Spontaneous corrosion localized damage is unavoidable, should the interval time of coating protective oil. 10 never overload. That is more than the maximum bearing capacity. 11 the use of the process should pay attention to not be knotted. Compressed. Arc wounded chemical medium erosion. 12 may not be directly hoisting high temperature object, for there are edges and corners of objects to be protective plate. The 13 use of the process should always check the use of wire rope, achieve discard as useless standard should be immediately discarded.
Hoist steel wire rope scrapping standard:
The 1 diameter is reduced in diameter to wear more than forty percent should be scrapped, not exceeding forty percent should reduce coefficient using. The 2 surface corrosion; when the wire rope surface corrosion to the naked eye obviously, wire rope can not use. 3 structural damage of steel wire rope broken; whole shares should be scrapped, broken wire rope should reduce coefficient using. The 4 overload overload; the use of wire rope should not be used.
National infrastructure of transportation of city construction, more and more large scale, used in the construction of hoist scale, power will be more and more, the traction speed more and more quickly, corresponding ground winch key transmission drum open gear pair structure dimensions does bigger more, large power, high speed operating condition of windlass noise is also more and more high, however this is not allowed by national standards. Building hoist the national standard GB1955 2002 provides qualified winch noise limits for machine shall be not more than 85dB ( A ), the operator shall not be greater than 88dB ( A ) ear. When the winch less traction, the low speed of the noise are far lower than the standard limit, control is easy; but when the traction speed is higher, the traction force is greater when the noise does not exceed the standard to ensure that, from the design, process, materials, quality and other aspects to take effective measures.
Winch noise sources in a variety of ways, but is essentially the result of impact and vibration, is generally the result of gear meshing quality is poor, unstable movement in the movement produced a transient acceleration caused by. My company a 80kN fast running hydraulic control hoist, steel wire rope traction speed is 30m / min, 55kW motor, machine noise is generally within the standard range, but occasionally exceed the standard noise phenomenon, a machine cannot pass the inspection. In the removal of noise are not start, because of the machine manufacturing is based on the same pattern, process, since the vast majority of products qualified, should eliminate unreasonable factors in design and technology. Noise source analysis and control is mainly we think chassis design and manufacturing resulting from the presence of noise may be: 1 chassis with box structure, not all welds are continuous welding, the weld length, height of the chassis, chassis rigidity large individual differences, some resonance effect, the machine such as a vibration noise amplification; 2 chassis by a plate welding, do not have the shock-absorbing silencing function, if its natural frequency and gear meshing frequency proximity may be caused by individual machines for gear weak vibration caused larger total shock, caused by noise value to rise. We are aiming at the possibility of tested separately, but by three experiments found that noise level and the chassis structure, stiffness, frequency and other factors were weakly correlated, the size of the noise and movement of pieces of strong correlation, so the chassis design structure, manufacturing quality and noise not exceed the standard of reason.
Bearing clearance has argued that, since the noise is accompanied by a drum assembly and transmission parts, it may be due to the reel sliding bearing caused by. We on the reel parts clearance selection, ensure the bearing hole and spindle clearance in conformity with the requirements of drawings, assembly test. Test of using frequency control of motor speed speed, observation to the effect of noise. Experimental results show that speed?, to the influence of noise is the first reel speed, higher noise value is increasingly big, machine vibration and more intense; gap in the second, main shaft and sleeve gap bigger noise is greater; and the chassis of the lowest noise. If the machine was very low noise level, then the velocity, spindle gap size changes will not have too much noise, so that the noise is also not exceed the standard bearing clearance caused by large.
