  • Analysis of tower cranes problem 2012/11/28 The large number of building a high-rise building, the tower crane its low costs, flexible working height, larger coverage area of the advantages are widely used in construction sites. However, a lot of examples of the tower crane accident at home and abroad, Some tower crane products for design reasons, some violation of safety procedures, and some unexpected situations handled properly, which also have a large proportion of the basis for overturning, foundati...
  • Select the correct building hoist up weight limiter 2012/11/26 For building hoist suppliers and users, the choice of a good starting weight limiter of performance, so that the proper use and maintenance, and extend the life of the construction elevator to maintain a well-run state and the production of safety-critical.Rated from the weight of the building hoist construction lift to allow lifting of heavy objects including fixed together with the sum of the weight of the spreader (for mobile construction elevator, construction el...
  • The building hoist reducer accident cause 2012/11/21 1, building hoist gearbox output shaft fracture surface fractureShaft fracture two regions, a smooth surface area, a coarse granular district, showing typical fatigue fracture fracture characteristics. Shaft fracture occurred in the shaft of the cross-section here is the stress concentration, the weak point of the shaft.2, the construction hoist reducer output shaft strength analysis and calculation(1) The hoisting mechanism of tower crane the frequently cyclical...
  • Automation products in tower crane industry 2012/11/20 Tower crane industry in China have developed rapidly since the 1980s, in recent years, the tower crane sales continued to climb. But it can not be ignored domestic models are relatively concentrated, the pressure of market competition, is not conducive to the development of the industry, which requires a series of reforms. At the same time, the product quality is uneven, steam dryer, lime rotary kiln, cement equipment, market access restrictions are not strict....
  • Trailer pump pump and mixer truck 2012/10/30 1.Trailer pump selection. Concrete pump machine we use common, there are two, one is walking pump with placing boom, another tractor fixed pump. Mobile pump, easy to move, but the price is more expensive, suitable for pouring small the shape irregular built structures. The fixed pump mobility cloth pump requires reasonable arrangement according to the construction site, but the lower prices, better suited to the building site is relatively fixed buildings and s...
  • Domestic dual-use tower crane 2012/10/29 By domestic production, the two types of products, are denominated the horizontal arm trolleying the QTZ80 tower crane foundation.Products will be the fabric duct mounted directly in the lifting boom, boom made folding paragraph 4. The first two paragraphs of the hydraulic drive, paragraph 3 of the wire rope luffing fully utilize the models cloth carrying capacity of the system to the structure of the tower crane, the largest fabric radius of 46m and conversion...
  • Trailer pump truck drive transfer case switch principle 2012/10/25 The trailer pump truck chassis adapted from, which is installed on the chassis movement and the power transmission apparatus, the pumping and stirring device, a feeding device, and some other auxiliary device. Concrete pump truck power through a power splitter box to send the engine power to the hydraulic pump group or the rear axle, hydraulic pumps promote piston driven concrete pump. Then use the booms on the pump and pipeline, will be the concrete conveying ...
  • Universal building hoist 2012/10/23 In the building hoist to the high-tech development, and at the same time we also clearly recognize that China's per capita income is low, particularly sensitive to the price, in this particular environment, the market is an urgent need for simple, reliable popularity construction elevator. In the future, this type of construction hoist more than about half of the total demand of the Chinese construction elevator. Type of construction hoist features:The construc...
  • Building hoist, tower crane trends 2012/10/21 Whether building hoist or tower crane, belonging to one of the engineering machinery, widely used in many fields of real estate, municipal engineering, industrial construction. Consolidated by the construction elevator network construction elevator, tower crane market characteristics and trends in research, in fact, the two are basically the same (tower cranes, construction elevators).In the early 1950s, China tower crane started by imitation. After the reform ...
  • Building hoist anti-fall safety inspection FAQs 2012/10/17 1, Building hoist movement speed centrifugal speed limiting device unstable centrifugal speed limit device thrown block throw off speed instability.The main reason is the spring failure; thrown block shaft rotation is not flexible; thrown the block fixed pin off and thrown block failure due support spring pieces.2, centrifugal movement speed of the speed limiting device calibration the normal assembled overall installation test, action, speed deviation from the...
