  • Rack and pinion building hoist 2013/1/15 Rack and pinion building hoist through the gears in the gear arranged in the cage and arranged a engage in rail frame rack and hoists for moving up and down along the rail frame to complete the personnel and material handling construction elevator.Rack and pinion building hoist structure is characterized by: the transmission drive gear, forcing hanging cage along the rail rack rack up and down movement; rail single frame is composed of standard section stitching. The...
  • Trailer pump hydraulic valve 2013/1/9 Hydraulic valve hydraulic pump "assistant", including the sequence valve, pressure reducing valves, valve, unloading valve, check valve and switching valve and so on. Domestically valve, unloading valve the Zhengzhou Unique Industrial Equipment Co.,Ltd. product is superior, but in a difficult sequence valve, pressure reducing valve technology, high reliability requirements on the valves to use German Hawe, Rexroth, American Eaton Wei Geshi, Italy A drag Sri...
  • The building hoist device requirements 2013/1/7 Building hoist motor and electrical components (except electronic components) of the insulation resistance should not be less than 0.5 M Ω, electrical wiring insulation resistance to ground should not be less than 1 MΩ.The metal casing of the metal structures and electrical equipment for building hoist should be grounded, grounding resistance is not greater than 4 n.The construction hoist foundation should be able to withstand all loads under the ...
  • The structural features of the tower crane 2013/1/5 Structural features can be divided into the pitch at tower crane boom luffing boom (boom) boom (flat arm) tower crane and trolley.Pitch luffing jib tower crane by unrealized luffing boom lift, its advantages are: simple mechanism can give full play to the effective height of the boom, the disadvantage is that the minimum amplitude is limited to 30% of the most substantial around, can not completely close to the tower, with the boom luffing load with lifting, not with...
  • Trailer pump motor power 2012/12/28 A trailer pump motor power to decide prerequisite outlet pressure and delivery, the amount of pressure rise, in certain cases of motor power, will make the throughput to reduce; Conversely, lowering the outlet pressure will make through putincrease.In order to ensure concrete pumps both have a larger throughput, but also to have some outlet pressure and economic power to match concrete delivery pump design, mostly using a constant power piston pump; constant power va...
  • Building hoist installation 2012/12/28 Building hoist installation before the installation of units shall prepare the construction elevator installation the Demolition of special construction program, approved by the technical person in charge of the installation unit, submit construction general contracting unit or units, supervision units audit and inform the location of the project above the county level administrative department of construction.The construction elevator type, model and quantity should...
  • Tower crane lifting moment 2012/12/26 The amount of rated lifting moment is the most important parameters of the working capacity of the tower crane, it is the tower crane prevention weight shift, occurred while tipping the key parameters. Uneven lifting torque due to different amplitude, amplitude grows louder, torque gradually, so often as to each point of the magnitude of the average torque rated torque of the tower crane.Correspondingly reduced with increasing amplitude of the starting weight of the ...
  • BK-type tower cap-shaped tower crane 2012/12/6 BK-type tower hat-shaped tower crane on a rotary tower crane, the tower does not turn the whole low moment of inertia. With the increase of the building, this form of tower cranes can be easily converted into a the attached tower climbing tower crane.BK-type tower hat-shaped tower crane supporting forms can be divided into fixed-rail running style. Fixed style is characterized by the tower supporting structure at the bottom part of the small size, small footpri...
  • The selection and arrangement of trailer pump 2012/12/5 Model of the trailer pump according to the plan of piping, pipeline level translation distance and average unit time required throughput is determined. The model of the concrete pump concrete type, quality, plan of piping and pumping conditions must be taken into account to determine.Of construction units should be based on concrete pouring plan requires the maximum output and maximum transport distance to choose the model of the concrete pump. In the pumping c...
  • The tower crane ceiling liter work 2012/12/3 Ministries normal to start jacking, the tower crane lifting beams really pawl falls lug of the tower, the top 0.8 m from the tower head departments and pawl falls tower convex sets of beamsear. To recover the cylinder top up beams hanging on a pair of lugs, Zaiding from the tower head departments, pull up the set of frame pawl, when oil all stretched finished about one meter re-set frame pawl. And then recover the fuel tank jacking beams pulled on from the towe...
