タイトルまたは説明

Self-raising tower crane is designed and manufactured by combining introduction of advanced foreign technology and products top-slewing tower crane. Fo/*3B tower machine adopt getting regular top of the tower, structure form space truss main string pole adopt the solid round steel for person who lean forward, the belly pole is a steel tube. It is the one slice of types structure to balance the jib, combine and links with top of the tower, of simple structure through the pull rod with the jib knuckle joint of the jack-up separately in the top of the tower. The one slice of types of the body of the tower structure is made up of 4 slices; high-strength bolted joint, transport it conveniently. Join while adopt Q**5B to forge the internal and external fishplate and *5Crom pivot to join and take one?? s place accurately between the bodies of the tower, it is safe and reliable. It is hoistway organization it has to be heavy to get up weight, it is hoistway speed fast and transfer speed range wide to get up, install and take one??s place the convenient, high advantage of working efficiency. Slewing parts adopt OMD step less to transfer speed; guarantee starting, it is take one??s place accurate steadily to apply the brake to construct to transform to go back. Become pieces of organization urge decelerator through it is realize 3 speed of stabilizing to control to pigeonhole to transfer directly by single speed moment electrical machinery, fault rate is low, maintain it conveniently. Traveling makes up main drive bogie in the organization by 4. 4 bring double of function disk type two speed electrical machinery of brake urge decelerator is it Guarantee through electric apparatus starting apply the brake steady. Various kinds of safety devices are complete, moment limiter, heavy working load and speed limiter most, hoisting degrees of limiter, slewing limit location device round, troll eying limit location device, etc
