The loader is a touch of dazzling color of the construction machinery industry in recent years, with the increase in infrastructure construction, used loader market is quietly rising, but the quality of second-hand loader on the market is good and bad. How to choose a suitable for your machine, is a headache to many users want to enter the engineering machinery industry.
Buy the machine according to the construction of the
At present, domestic second-hand loader 8 to 300 tons tonnage of over 10 products. The user\\ s economic situation and will have to face the construction of the most important basis for the purchase of the machine, and what conditions determine Which machine can bring the maximum input-output ratio.
First of all, for road construction operations and large-scale coal mines, due to the heavy workload, the duty cycle is longer, more spacious working environment, a matching transport machinery load of 10 tons or more, then you should select five tons or 6 tons deadweight loaders, which can improve operational efficiency, reduce construction costs. For a relatively small amount of work situations, such as earth, sand, etc. generally choose a load of 3 tons or 4 tons of products, very small amount of work, such as small individual gravel pits, supporting vehicles for small tractor generally choose the 1.5 tons or less of product in order to avoid the loader operating excess capacity, so as to achieve the economic and practical purposes.
Again, according to the operating conditions to determine the appropriate speed loader. Greater density of ore, solid original soil or the smaller the density of loose material such as soil, coke, etc., due to its working condition is different, the loader choose the same large difference.
For those larger density of the solid original soil, ore and other materials, due to the higher traction (insertion force), should choose the lower working speed, breakout force and tractive larger products to ensure the normal use. Because of the loose material loader traction (insertion force) do not ask, you can choose a higher driving problem in order to obtain higher efficiency.
Two mobile phone market to find the \"treasure\"
There are a number of second-hand loader market, these markets is littered with some of the machine in good condition machine, but a pair of \"eyes\", accidentally see Zouliao Yan \", and its loss, but users heartache.
Into a second mobile phone market, in the face of an array of machine, which is your \"true love\"? Which is the seller set a good trap? Was supposed to be a fair and transparent market, the frustration of users who have to match wits with the game in a field. Prepared several information to their own book, the wheat from the chaff, over five hurdles, put on their satisfaction with the machine to go back is the ultimate goal.
Used loader to see the machine when the attention of:
1, and appearance. Resolutely do not paint the car. You have to believe that they did not so lucky. The appearance of another new machine is good and the vendors will sell you such a low price? Even if the machine is genuine, I am afraid it has long been snatched. Attention to matching the entire vehicle number, engine number, chassis number, bridge, the Liugong car should the cab there are numbered. The frame number of a work vehicle with a white paint brush in the left front fender behind a bit. The normal number date will not be apart for too long, generally not more than three months, more than long necessary to consider whether the renovation of assembly.
2 frame. Closer look at before and after the frame cracks, weld touch-up painting. , Depends on the location is not important, vital parts of this machine is not taken into account, not a vital part to ask why.
3 tires. Do not just look the tires of old and new, the new full turn tire tire to see what brand to go check, note; full retread Note the rims (tires and rims of the cracks inside) around the authentic tire is smooth and tidy, tire retreading is generally not smooth and tidy; half a retread is easier to see it. Tires depends on the teeth, the edge of any opening the size of the opening, with or without playing complement. Recommended as long as the edge of the opening as the reasons for a bargain. Edge of the opening is easier to puncture, Hang a tire should be around 7000.
4, the pressure tank. Open the fuel filler, smell or without the pills only to discover Road, described high temperature. The use of rulers, a drop of oil drops in white, non-reflective paper to see whether the aluminum alloy powder, a turbine there; normal oil should be clean, reddish. This project is best to dry the car for half an hour of live view. Abnormal sound should be able to hear it. Change the turbo processing fee to about 2000.
6 engine. Appearance should be clean, no oil spill floor antifreeze check whether sensitive, start cold startup should have a slight blue smoke, heat blue smoke, fuel door slightly smoky, basically do not take under the exhaust normal smoke cigarettes, should be white, if we should be careful to take the blue smoke, a little experience, is to see the engine coolant is water or antifreeze, add antifreeze machine owners are more to understand the machine is very protective of the machine and, if possible, open the air filter to see if the inlet is clean very clean and protect the good machine inlet.
7, front and rear axle, wheel side. EMU turn to listen to the sound. Differential price of 800, more than 1000 of the basin corner tooth Price Wheel priced at more than 1000, about 500 working hours, fees
