Electric wire rope hoist

After the wire rope hoist used for some time , the gear will be worn, what is the reason for this liftech motorized chain hoist phenomenon is formed below us ; ? Do a detailed analysis .
Transmission gear wire rope hoist on another failure mode is wear, worn tooth thinning. If there is wear due to impurities in the oil , generally referred to abrasive wear. This wear often occurs in the deep channel scraping tooth top and root scraping section perpendicular to the line track and parallel to each other . After scraping the road appears to rise in the gear unit oil , gear shrill noise occurs , then you must replace the oil . Because tooth deviation installation center distance deviation is too large , may cause tooth gear pair top edge portion of the transition curve and the tooth root excessive compression , so that part of the tooth root fillet produce severe wear. Due to overload , tends to make the drive wheel tooth or teeth of the driven pulley of the top ( also sometimes occur along the entire tooth surface) of a thin layer is worn away . Lifting gear reducer mechanism for the wear, tooth thickness of not less than 60% of the original tooth liftech portable electric hoist thickness for wear after running gear tooth thickness institutions should not be less than 80% of the original tooth thickness exceeds the standard should be replaced with new gear . Tooth wear can be measured with a thick tooth pitch circle caliper measurements to test the tooth thickness . Measuring method shown in FIG . Caliper Caliper is a comprehensive measure tooth vernier caliper and depth gauge , used to measure tooth thickness . When measuring , starting with drawings isolated tooth height ( ie, from division to round the top of the tooth height ) , the vertical scale measuring tooth caliper raised the height. Then, the card foot stuck teeth , tooth thickness measurement with a level of scale . Measurement accuracy up to 0.02mm.

Single rope winding lifting equipment

An earlier onset , it is reliable, simple structure, but only for shallow and medium depth of the mine , and the terminal load is not too large . For deep wells and the terminal load is large, a large rope and hoist upgrade roll diameter , resulting in a hoist equipmentlarge volume , gravity soared, making the hoisting rope and hoist the manufacture , transport and use on both inconvenience. Thus , to a liftech cheap wire rope hoistcertain extent, limit the single rope winding hoist used in deep well conditions. Friction appears to enhance its development machine , to a certain extent, solve the single rope winding hoist that appear under the condition of deep problems. However , things are always divided into two . Generally used to enhance the friction tail rope balanced tension at both ends to reduce the error and improve reliability. Thus , the container connection with hoisting rope rope section , the static stress changes with position changes of the container . When the container is located in the unloading liftech hoist and trolleyposition the wellhead , the gravity of the entire container and the end of the gravity are acting on the rope of the section ; arrival when the container bottom before loading position to withstand only the gravity of the section of the container. In other words, the entire upgrade process, with the hoisting rope section of the vessel to bear in connection with an amplitude of . static stress changes σj = qH / S0 of (q is the tail rope per meter gravity , N / m H as lifting height , m S0 to enhance the cross sectional area of ​​the wire rope , cm2).

Notice hoist equipment bucket elevator

Bucket elevator for vertical CDD electric chain hoist lifting through the limestone crusher , coal, gypsum, clinker , clay and other dry granular materials and raw materials, cement , coal and other powdered materials . Depending on the pace to run the hopper , bucket elevator can be divided into : three forms of centrifugal discharge , gravity discharge and hybrid discharge and so on. Centrifugal discharge bucket faster speed for conveying powder, granular, small block and other wire rope hoist manufacturers small abrasive materials ; gravity discharge bucket slower speed for bulk transport , a large proportion of , large abrasive materials , such as limestone , clinker and so on.

Introduction to the control circuit and maintenance of electric hoist

Electric hoist is a small weight, simple structure of a kind of hoisting machinery, widely used in industrial enterprises in the lifting installation of small equipment, has small occupied area is small, convenient use, etc. Electric hoist have two hoisting mechanism and a mobile device, structure associated with each other, they are all have Manual block own motor drive. Electric hoist lifting and lowering is motor driven by gear box for car motor through the role of the idler pulley, walking back and forth on the h beam movement, rising and falling, by line with limit switch to control the itinerary. Commonly used electric hoist are: 2 t, 3 t, 5 t with conical rotor motor, motor stator and rotor are tapered, after electrify with the establishment of the magnetic field and rotor shaft Hoist and trolley the fan wheel to overcome the spring force to produce axial movement, fan wheel conical brake ring out of the back cover, out of control, the rotor of the motor can operate freely, cone-shaped brake laps in the spring when the power is cut off, and back cover tightly closed to control the braking of electric hoist motor circuit consists of: circuit breaker, contactor, transformer, terminal, control handle button, thermal relay, wires, slide wire cable (mobile), and other electrical components.

Lever hoist is defined

Lever hoist is obtained from human pull (handle) chainb lock the aid of lever principle and load matching line traction, the rotation effect on movement load within a block, drive the load operation. It has compact structure, light weight, small dimension, easy to carry, safe and reliable, long life, small lever force, the wire rope wear small, etc. It can be upgraded, traction, drop, calibration etc. If a particular device, not only can be used as a non linear drawing operation, and can be very convenient to hoist equipment the appropriate operating position, or in small tonnage machinery exponentially expand its load capacity, load a number of machines can be used for large tonnage joint operations. Chain lever hoist is a kind of light is small, multi-purpose manual lifting, traction machine, widely used in electric power, mining, shipbuilding, construction, transportation, post and telecommunications departments such as the installation of equipment, lifting, part drawing, bulk, bundling, line taut and welding counterpoint, etc, especially in small workplaces, field aerial work and different Angle of pull more show its superiority.

Double beam bridge crane operation procedures before work

Double beam bridge crane operation procedures before work
1, before starting work on the brake, hook, rope and safety devices such as parts inspection, according to the requirement of the check card of abnormal phenomenon, should be ruled out.
2, the operator must be confirm there is no person, walk or orbit can be closed the main power supply. Lock on when the power supply circuit breaker or a billboard, should by the relevant people get rid of rear can close the main power supply. Chain electric hoist, including: low hanging type chain electric hoist, DHP were studied.the chainb lock processing type electric hoist, electric chain hoist, DHTZ type electric chain hoist, YH chain hoist, group of rings chain electric hoist. In all parts of steel wire hoist equipment electric hoist, professional production, high quality information to bring you the best quality products.
Reducer, helical gear transmission mechanism is to use level 3 a fixed axle, gear and gear axle has been heat treated alloy steel, box, box cover is made from high quality cast iron, assembly, sealing is good.
Control box: can is used to cut off the main circuit in case of an emergency, and up and down with a trip to protect fire stop device.
Type: wire rope is to use hoisting wire rope, it ensures the durable. Taper motor: lifting motor with large dynamic torque conical rotor asynchronous motor, brake and brake. Push button switch: using hand type, light and flexible, points with string manipulation and wireless remote control in two ways.
Professional, high quality good faith production force more force hoisting machinery products, safe and reliable, economical and practical.
