Cantilever crane lifting (1) pre-assembled, the first test beam segments (especially mating surface) geometry, embedded parts location and mark the axis of the beam segment and a landmark measure, according to the cantilever erection requirements, the reinforcing member in the local setting, segmental temporary tension preload structure, after all the preparations in place, you can start Cantilever Erection. First paragraph l # symmetrical assembly Shandong cantilever crane, through the beam transport vehicle will be transported to the bridge l # segment, direct lifting crane hanging fight, vertical position. (2) the beam segments matching filler surface coated with epoxy and cement binder, coating evenly, thickness control at 1.5mm, and the use of the coating thickness varies up and down to adjust upwards and fight cantilever crane down phenomenon, through local and temporary tensile reinforcing members pretension structure, further connected cantilever crane mating face, after wearing bundle tensioning tendons longitudinal girder segment until after the next assembly beams, vertical tensioned prestressed reinforced . (3) Segmental when applied to vertical tensioned prestressed temporary finishing rebar, post-tensioning, grout immediately, until the next segment after the lifting of the closure of this segment of the anchor to ensure Hanging Cantilevering After the anchor force machines. (4) When the segment to do linear control Cantilevering Guangdong cantilever crane, measuring instruments tracking, and direct contact with the lifting of command, so that timely control of cantilever beam crane hanging fight linear. Must be on linear (height, midline), etc. before and after each segment of the beam positioning accuracy measurement, monitoring and timely data collection and analysis, for the next beam segment Cantilevering control provides parameters, good linear control of the next segment of the beam . Cantilever crane jib crane hollow steel structure, light weight, span, lifting capacity, economical and durable. Built-in running gear, made of special plastic to go round with rolling bearings, friction is small, walking briskly; small structural dimensions, particularly conducive to improving stroke Xinxiang City Constant crane hook lifting equipment Co., Ltd. is a design, development, production and sales of manufacturing enterprises, philosophy; adhering to the "quality first, customer first" purpose of continuous progress cantilever crane maintenance, strive for perfection, to first-class products, quality service to meet the needs of our customers. Integrity, innovation, efficiency, quality for the purpose of quality, first-class service business philosophy, to meet market development. Precautions regular brake inspection, maintenance, brake lifting mechanism must once per shift, brake mechanism to run once a day, mainly to check the following: 1, hinges or without catching and wear, the fastening Department has No slack; 2, the operation of each of the movable member is normal; 3, the hydraulic system is normal; 4, between the brake wheel and brake band wear is normal, is clean. Cantilever crane maintenance, Xinxiang Constant crane lifting equipment (certified), jib cranes from Xinxiang City Constant crane lifting equipment Limited. Xinxiang City Constant crane lifting equipment Limited (www.xxhlqz.com) (www.xx.com) is an industry leader in Henan Xinxiang, hydraulic machinery and parts, over the years, the company is implementing the scientific management, innovation and development, honesty and trustworthiness policy, and satisfy customer needs.
