Gate hoist lifting power of the main parameters, gates open or decrease (closed) traction or pressure is applied, the opening and closing stroke and opening and closing speed. When you select the type of hoist, the main consideration of the following factors: the gate form, sealing size and operating conditions, the same number and type of gate opening set fan gate count, the number of gate lifting ear, opening and closing force and closing speed headstock stroke hoist power conditions, locations of spatial scales and other operational requirements. Screw hoist can be divided into: flashlight dual screw hoist hand push screw hoist, hoist side shaking, such as several manual screw hoist directly or via a threaded rod guided slide , link with the shutter door leaf connected mobile screw up and down to open and close the gate of machinery. Supported within the bearing nut screw, nut and drive mechanism (bevel gear or worm gear) fixed to the support frame. Powered or hand crank drag human transmission, drive the bearing nut rotates, the screw lift gate to open and close. Screw tension member is under pressure, under pressure required to force the gate dropped when calculating stability struts. Simple screw hoist, rugged gate hoist, low cost, suitable for small plane gate and gate, its lifting power is generally less 200kN. 500kN, 750kN high capacity screw hoist has been produced for the dive hole flat gate and radial gate operation. Fixed hoist for water conservancy construction engineer who hoist xzqbj, will come into contact sluice construction, however, when the sluice 0.5 construction hoist, hoist how to install it? Fixed Hoist What are the requirements? For stationary hoist, the lifting gate mounted mainly reference to the center of the longitudinal and lateral deviation distance should not be less than 3 mm, the horizontal deviation should be less than about 0.5 per thousand, and the elevation of the deviation can be achieved 5 mm. Screw the process of carrying out the screw and the gate hoist connection, the deal will not be greater than the vertical deviation 0.5 per thousand; we need to conduct a comprehensive inspection and testing work at the hoist installation. To off-type gear and bushing full rotation, and clean processing oil and iron in the rotational areas, mainly to remove dust, plus the new oil, and in accordance with the instructions in the gearbox installation, but also to be treated in accordance with product instructions and regulations refueling oil level. When we conduct positioned hoist, foot frame to be processed at the end of the bolt handle concrete pour, the base of cement mortar and concrete must be used for landfill. Our door installation process, a comprehensive inventory of the whole investigation, but also on the machine's components to install, the installation process, the deviation must comply with the relevant provisions of the drawings hoist, if not the exact provisions You can refer to the corresponding requirements for execution; for when the track door installation, assembling the door if there are deviations, it should be based on the content of the drawings and specified in the manufacturer's instructions for installation.
