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 gate hoist, hoist power status, locations of spatial scales and other operating 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 structure, durable, low cost, suitable for small flat gate and radial gate winch hoist, 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. Manually screw hoist can also be referred to as "hand screw hoist," which is a manually operated hoist plane gate devices. The hoist gate can stay in any position to complete the self-locking is very advanced equipment. Screw that has shaken lightweight hoist, hoist flexible, fast turning speed, hand start and other fine features. , Large and small gear, pressure bearings, nuts, screws, hand crank. 1. Before installing the screw hoist basal plane at the base level to ensure that the premise of the base of the hoist must be more than 90% of the area in contact with the base plane. Screw axis to be perpendicular to the horizontal plane as measured by the gate stage should avoid screw tilt, causing partial fragments of mechanical stress. 2. The installation manual screw hoist into position. The disc sets a limit on the screw, the screw from the lower portion of the beam onto the machine, after the screw is exposed from the top of the machine, and then put on the stopper plate. Beneath the gate of the screw connection. 3. For the installed base must be firm and safe hoist. Concrete screw hoist frame and the base member, according to the provisions drawings pouring concrete strength at the time did not meet the design strength, are not allowed to remove and change the temporary support hoist, but can not reconcile commissioning trial. 4. When installed according to the centerline of the gate lifting, aligning the center so that the vertical and horizontal centerline deviation does not exceed plus or minus 3mm, elevation deviation does not exceed plus or minus 5mm. Then pouring concrete or connected with two embedded steel. 5. For the installation of electrical equipment products, must comply with drawings and specifications, and all the electrical equipment are reliable ground. 6. Install the product is finished, the machine must be cleaned, Repairing damaged protective paint, pouring grease.
