Excavators rotary turntable repair and maintenance skills, very useful! Rotating turntable portion includes a slewing ring, gear, and other parts of the center section. Usually we open the cover next to the base of the boom can be observed cavity ring gear lubrication, and ring wear. With the use of the machine, dust-turn center section will appear at the aging, in case of rain, the rain will follow the rotational center section slatted infiltrated the ring gear of the cavity, causing the water wheel. This will greatly affect the love machine rotating ring gear life. Excavator Excavator operation, butter cavity due to the dilution water, lubrication not up to standard, it will exacerbate the wear ring, another long soak will ring on iron peeling, mini-excavators manufacturers, resulting in abnormal noise rotation. The most serious is the ring gear failure. Inspection and maintenance: general rotary gear inspection and oil change cycles every 2000 hours or one year, 20 tons of butter filling machine capacity of 36 liters (two barrels). To open the arm base on a regular basis, four types cover the front of the frame to check the ring and lubrication. Maintenance or water can be found at the bottom of the digging machine X Overhead chamber to open the cover release water. Rotary bearing maintenance and maintenance on the swing bearing maintenance customer widespread misunderstanding that the rotary bearing lubricating oil with the same period the size of the arm, spank. In fact, such as but played the opposite role. If the lubrication cycle is too short, too much oil will make the bearing, thereby bursting the dust seal leaked. There will also be leakage of contaminants into the interior of the bearing, never harm the normal operation of the bearing. Caterpillar slewing bearing lubrication intervals recommended every 250 hours. Butter and down while playing, in play while rotating machines, each 15 ° Catch a gun lubricant that is enough. In various applications the lubrication cycle can be adjusted according to the intensity of your job, usually about 1 week lubricated once.泰安嘉 and Heavy Machinery Co., Ltd. Construction Machinery emergency repair of several large-trick when bundling engineering machinery somewhere bolt break or the slider can not be tightened, it may consider sticking lashing wire and sticks, etc., how much small excavators to temporarily resume operation. 74 excavator as pressure mechanism when damaged, the front axle is not connected, off-road performance used mini excavator price, the machine fell to the suspension can not lock cylinder. When you need to turn on the front axle, fork shaft and the cylinder can be separated and push in the fork shaft, then the circle at the fork shaft is fixed, so can ensure drive the front axle. Similarly, if the suspension or the brake mechanism hydraulic cylinder when the pressure is reduced or no pressure, Baoding mini excavators, may adopt such aid approach. Second, the demolition without compromising engineering machinery operation, removable and do not stretch out temporarily damaged parts. For example, the diesel generator damaged removed, temporary short supply batteries to the starter system. After some mechanical disassembly after a simple repair Commissioner, still emergency use. As gas is produced diesel let damaged, it can be removed for grinding, sealed and returned with the valve seat, it can temporarily use. Third, if a short circuit engineering machinery starter system or a component of the control circuit after the damage, neither repair nor replacement of spare parts, such as the use permit, may be considered to be short-circuited phase, emergency use. But not long-term use, often due to a short circuit after phase will increase the amount of heat in the circuit, it is possible to burn other circuit elements, damaged parts must be replaced immediately be conditional, to avoid a new failure.泰安嘉 and Heavy Machinery Co., mini excavator price list | Baoding mini excavators | Kerry and Heavy (View) by 泰安嘉 and Heavy Machinery Co., Ltd ..
