Forklift tire abnormal wear and Prevention

Forklift tire abnormal wear in use in general there are six types: one is the fetal excessove wear; two is the crown two shoulders of abnormal abrasion; three is turned towards the inside tire crown wheel (or lateral) extraordinary partial wear; four is the crown serrated wear; six is the crown of partial wear. Mainly for the uneven tread wear, delamination between plies, loose cord and broken and the resulting matrix cracking. off road rough terrain forklift‍ driving, each part of the tire force is more complex: in a vertical direction of the vertical reaction force, tangential direction is vertical and horizontal reaction force, so that the tire slip existing whole or partial in these directions, cause the tread wear and deformation; tensile, compression in the matrix generated inside caused by fatigue of materials, thus reducing the strength; shear stress is induced in between plies, when the stress exceeds the adsorptive power cord fabric layer and the rubber interlayer, there will be loose cord phenomenon; in the tire deformation, friction heat will occur between the outer tube and inner tube, a part of the heat quantity emitted into the air, another part of the heat accumulation, lead to the decline of tire temperature rise, performance, so that the tire abnormal wear increase, cause the loose cord, broken and matrix cracking. Under certain load and driving conditions, off road forklift trucks‍ tire has a proper tire pressure, when the tire pressure is lower than the standard value when driving, tire radial deformation increases, both sides have excessive deflection, so tread on both sides of the inner wall of the grounding, the side of the tire pressure, tire side wall tension, tire body cord deformation and great alternating stress. Compression deformation of periodic damage, fatigue will return speed cord, tire cord fabric layer and between the tire and the ground is increased relative slip, friction heat increased, the tire temperature rise sharply, reducing the tensile strength of the rubber, loose cord and local delamination, encounter obstacles during impact produced a flat tire. Tread pressure is not uniform, so that the shoulder parts wear serious, leads to the "bridge effect", the tire is dentate or wavy. The tire tread concavity easy embedding road nail and stones, causing mechanical damage. Tire rolling resistance increased, increased fuel consumption. Experiments show that, when the tyre pressure is lower than the standard value of 20%-25%, the corresponding increase in 20% consumption. When the tire pressure is higher than the standard value when driving, the tire crown central ground contact area decreases, the tire and the road surface, load per unit area increased, crown central increased wear. Tyre cord by overdistention, carcass cord stress increases, the fatigue process of cord is accelerated, causing cord pull off, causing early burst tire.‍

Extend the forklift clutch separation method of bearing life

Abstract method to extend the off road forklifts‍ clutch separation bearing life: when considering the repair of mechanical reliability statistical analysis method of domestic CNC machine tool shank standard Mitsubishi heavy industries launched large-scale Longmen type five face machining tool pressure welding technology and new development of differential shell spherical NC cutter design "Dalian machine phenomenon" Reflections on the radius of screw pile machine successfully trial produced new mold molding the processing technology of three hole part programming source bearing failure prediction and prevention of mechanical processing system and the error of aspheric lens grinding and inspection of gear measuring machine related parameters of tool compensation function of the new cam shaft grinding technical analysis of safety light curtain and switch - used in mechanical safety of personal protection god bearing installation method and remove the fast clamping the principle of Russia developed small mobile type wind generator NC drilling machine - milling process life prolonging bearing clutch damage method separating lubricating overflow engine forklift clutch separation bearing life prolonging method of internal combustion forklift clutch bearings working times larger proportion of frequent damage of forklift driver operating properly in time using the left and right bearing maintenance repair to change new the driver technology of water Flat drive forklift almost every separation bearing damage damage affected parts of the clutch lever equipment repair materials Fei Mingxian to improve the clutch.

Method for prolonging forklift clutch separation bearing life

Internal combustion forklift clutch separation bearing work frequently, the damage accounted for a large proportion in the number of forklift driver, if operating properly, timely maintenance, can make the bearing use about 3 months, but in repair is to be replaced. If the driver technology level is low, the driving off road rough terrain forklift‍almost every month there is separation of bearing damage, damage will bring disaster to the other parts, such as the separation of a lever and a clutch plate, thus equipment repair material costs significantly improve.

Causes of clutch separation bearing damaged easily where? In practice, has strict requirements for driver daily separation bearing a drip oil, this is not only tedious operation, and the bearing is often damaged. According to the analysis, due to the high temperature engine isolation bearings, and the bearings of high speed rotating also produces high temperature, under these conditions the oil is very difficult to remain in the bearing and bearing of continuous working in the condition of high temperature, and the lubricating condition is not good, this is the reason for frequent damages.

In view of the above question, also had a bearing test will be heated in the grease, the grease soaked to the bearing, thus treated, although full bearing grease, but due to the destruction of grease structure after high temperature treatment, performance is greatly reduced, the use of this method the effect is not ideal, the service life of the bearing no extension. We also used nose grease gun to the separation bearing direct injection of butter. To install on the bus, after observation of detection, greatly prolong the service life of the bearing. This method of fuel injection get satisfactory results, but the operation is more complicated. And then to explore in the engine apart under the condition of adding butter, first in the 475 C type engine trial success, and again in 480, type 475C and type 492 engine trial, have received very good results. After repeated practice, improvement, sum up experience, has formed a set of relatively simple oiling operation method, the specific process is as follows:

Method of fuel injection (L) engine apart first open the clutch cover, view wear check release bearing, if confirmed bearing without damage or wear not overrun, remove the clutch pedal, an adjusting connecting rod shaft pin, so that the separation of bearing and seat back to last position, with a sharp mouth grease gun to the hole filling grease bearing seat, until the bearing oil overflow, then slightly rotated about bearing oiling, again, repeat the above work, until the bearing are all around a little butter overflow, then the bearing to rotate, observe the amount of oil, such as feeling the rotation of the bearing resistance, prove bearing have been filled with butter. Then remove a little butter separation throughout the overflow of the bearing seat, the pin and the clutch cover re assembled remove.

(2) the oil injection method of disintegration disintegration engine will expose engine fittings separation of the bearing and the bearing seat, small oil using pointed nose grease gun to release bearing seat below the inner hole of the bearing gas, butter overflow when the rotation of the bearing, bearing a lap until butter overflow.

After processing of the above two methods, the separation of gas bearing can no longer within half a year. This set of oiling method in HengShui Railway Station after the trial, mechanical integrity rate increased significantly, has obtained obvious economic benefit. It can save material costs; improve the loading amount, per machine per month can increase the handling capacity of 30t. This method also worked in other railway station promotion, achieved the ideal effect.‍

All terrain forklifts off road rough terrain forklift

Must adhere to the principle of prevention,All Terrain Forklift maintenance usually will be in the end, Wheel Driving Diesel Forklift can effectively prevent the occurrence of the problem before forklift truck maintenance. So to maintenance institutionalized, standardized and scientific efforts to improve the efficient use of forklift trucks. Maintenance divided run-in period and maintenance, forklift routine maintenance, YTO Rough terrain forklift manufacturers seasonal maintenance, storage maintenance and regular care and other five. Today with the running of maintenance based.
Forklift new factory or overhauled within the time prescribed running-job use, known as forklifts run-in period. Internal combustion forklifts run-in period of work is characterized by: Parts machined surface is rough, battery operated forklifts poor lubrication, increased wear, easy to loose fasteners, provisions must be run-in period for maintenance and use in accordance with the internal combustion forklifts.
Run-in period of internal combustion forklifts: Start with 50-hour break-in period.
Run-in period, three tons of internal combustion forklifts from the weight must not exceed 600kg, lifting height is generally not higher than 2m. Speed ??of the engine shall be high speed, speed limiting device shall be adjusted or removed, the speed should be maintained at 12km / h or less. In accordance with the proper use of fuel and lubricants. The right to correct start driving and operating the engine warm-up to more than 40 degrees in order to start; started to have a smooth, until the temperature to normal after an upshift; suitable shift, avoid crashing; choose a good road; try to avoid the emergency brake; Use close attention to the process of transmission, drive axle, wheel wheelchair, brake drum temperature; when loading and unloading operations, strictly abide by the rules.
