Practice a hoist. Construction units, to hoist should be installed on a flat solid, good view of the ground, the body and must be firmly anchor. Requirements hoist should be vertical centerline of the guide pulley alignment, distance pulley hoist should generally be not less than fifteen meters. 2. Before transfer loading operations, should check the rope, clutches, brakes, insurance ratchet drive pulleys, etc., to determine the safe and reliable operation only. Wire rope on the drum must be neat hoist gate, the need to retain the job at least three times. When the job, it was not allowed to cross the wire rope hoist by preventing accidents. 3. When lifting heavy objects need to stay in the air, in addition to the use of brakes outside, and apply the ratchet insurance card prison. When the operation is strictly prohibited without permission to leave their posts. 4. Work to obey the command staff of the signal, the signal is unknown or may cause an accident, you should suspend the operation until after clarifying the situation may continue for hoist industry. Jobs sudden power failure, should immediately pull the knife, and the delivery of objects down. INSTALLATION hoist device fixture types of fasteners shall require the acquisition and processing of construction drawings. Fittings machined screw hoist should be straight, no distortion, no curling incision should burr. Fasteners installed in place, and by measuring the check and correct winch hoist, should be fixed immediately. When using a fixed welding shall burn fixture Face; When using temporary bracket, bracket should have sufficient strength and rigidity. When pouring concrete or backfill, keep fasteners in the correct position. Fittings must not cross settlement joint or joints. Along the same line, the same type of support and hanger spacing should be uniform, smooth vertical and horizontal and tidy. Backfill concrete or mortar should be carefully tamping process to ensure that bond firmly embedded parts, as well as old and new concrete or mortar fully bonded, exposed concrete or mortar backfill must be smooth surface, and the conservation and protection. Quality fasteners embedded, we will work with the supervisor according to the quality standards specified in the tender, for embedded fasteners for quality inspection, and make records. Hoist brake parts from truck transport to the top of the platform hoist, using 25t truck crane hoisting place. Both fixed axis hoist winch using theodolite set after examination by Level hoist base elevation, first install base, followed by installation of the coupling, after adjusting the position of acceptance, according to the construction drawings The provisions were two concrete backfill. When the second phase has not yet reached the design strength of concrete strength, are not allowed to change the hoist mounting support, more may not startup. Hoist installation machine electrical equipment, according to the drawings and technical specifications with the manufacturer of construction and all electrical equipment should be grounded. Finally, the installation of wire rope. Fixed hoist winch after the installation is complete, you should perform the following items in conjunction with the supervisor's test: Test requirements for electrical equipment to perform according to DL / T5019-2004 provisions of Article 5.3.1. PLC control for electrical control equipment should first software debugging normal analog signal is correct, then the on-line debugging.
