Q:What elements should I take into account when purchasing a car?: In determining the purchase with the crane to at present on the market have a clear cognition, have a certain familiarity of the freight industry, at the same time, the freight market is changing, relying on the traditional rough operation will be difficult to survive in the fierce competition in the freight industry.First of all, before deciding how to buy a car, it's important to understand why you want to buy a car. What's the real purpose of your own car purchase?. They have no fixed line transportation and supply, and how the level of profit, which is the most important, if there is no fixed line or supply, road freight transport in the current competitive market is extremely fierce, rush into the freight market, rely on the guerrilla picking operation, is bound to bear great pressure, it is to stay in business.

Q:Do hardware or plastic factories have no need for cutting tools?: Hardware parts pointing on more widely, such as: screws, panels, hoses and other metal accessories.

Q:What important attention should be paid to large equipment?: Lifting tools are not allowed to exceed nameplate, safety check is carried out every month.

Q:What's the difference between a horizontal jack and a vertical jack?: Vertical jack: using hydraulic principle, different from the traditional mechanical jack, it has the advantages of easy operation, safety, reliability, labor saving, mobility and so on.

Q:What are the protective measures against crane injuries?: Crane type selection is reasonable, the road is flat and solid, and should not work on the slope.

Q:What are the points for attention in the course of transportation of double beam cranes?: The provision of means of transport, including the conveyance of vehicles and lifting tools, materials, etc..(1) the selection of transport vehicles and lifting tools. According to the shape, size and weight of the components, site transportation, lifting tools, road conditions and economic benefits, determine the appropriate type of vehicles and cranes, number of units and mode of shipment.(2) prepare tools and materials for shipment. Such as wire ropes, chains, clasps, baskets, bolts, jacks, flags, mats, boards, old tyres, etc..

Q:What is the working principle of a screw jack? What's the difference between an ordinary hydraulic jack and an ordinary hydraulic jack?: The piston will slowly rise, can not see), lift power transmission by spiral, formed a large thrust (x = thrust pressure area), hydraulic oil pressure acting on the piston in the piston, push upward, in the lower part of the piston, screw nut stop, hydraulic oil through the pipeline (in the case, as with a wrench bolts / pressure, small piston pushes the hydraulic oil, the bolt will be stretched out.

Q:Please explain how to prevent the safety accidents in the process of tower crane installation and disassembly: Tower crane disassembly method and installation method is the same, the program is just the opposite. When folded, the building has been built, and the site is not so spacious as to be installed. Therefore, we should never take it lightly.1, tower crane demolition of the basic requirements and installation of the same.2, the process of disassembly is strictly prohibited to use cutting scarify.3, remove the bolts, pins, and spare parts should be packing plate joint custody.4 、 the operation room is closed with iron sheet.5, the rotating machinery for maintenance, oil, sealed.6, the appearance of paint anti-corrosion.7, after the removal of tower cranes, conditional storage of the storage of some parts, unconditional storage part of the transfer to the vicinity of the special line stacking, ready for shipment.

Q:The principle of an air compressor for connecting two pistons: In order to improve efficiency and reduce air temperature, intermediate cooling is needed. As the piston type air compressor air compressed by two stage low pressure cylinder pressure from p 1 to p 2, T l to T temperature by 2; and then flows into the middle cooler, at constant pressure of cooling water heat, the temperature is T L; the high pressure cylinder compression pressure to 3 P. As can be seen from the diagram, the air temperature T, l and T 2 entering the low pressure cylinder and the high pressure cylinder are located on the same isotherm 12 '3', and the two compression processes deviate from the isotherms. The same compression ratio p 3 / P 1 single stage compression process is 123 ", which is much higher than the two stage compression deviation from isothermal 12 '3', that is, the temperature is much higher. And the single stage compression work is equivalent to the area of 613 "46", and the two stage compression work is equivalent to the sum of 61256 and 52 '345 in the figure, and the work saved is equivalent to 2' 23 '32'. It can be seen that the staged compression can reduce the exhaust temperature, save compression work and improve efficiency.

Q:Is there a good steel lifting machine, the crane always binding steel plate, the efficiency is not high?: The easiest thing to do is to use a special hook for lifting iron (heavy lifting) and a manual magnetic sling under the wire rope.
