QTZ125 Tower Crane Mast Section and Bolts<\/h2>\n

A QTZ125 tower crane mast section<\/strong> must be identified by more than the QTZ capacity designation. Different manufacturers can use different tower systems, connection patterns and bolt specifications under similar crane descriptions.<\/p>\n

\"qtz<\/p>\n

1.Performance parameters of QTZ6515-10T: performance parameters and technical indexes reach both domestic and international advanced level.<\/p>\n

\u2022 Max. jib length: 65m; Jib length under different assembling modes can decrease progressively by 5 meters and the Min. jib length is 40 meters.<\/p>\n

\u2022 Max. lifting capacity 10t;<\/p>\n

\u2022 Max. hoisting capacity at jib tip: 1.5;<\/p>\n

\u2022 Max. lifting moment 1250 t.m;<\/p>\n

\u2022 Max. free-standing height: 45m; Max. working height of anchored crane: 180m;<\/p>\n

\u2022 Hoisting mechanism power: 37 KW; rope capacity: 480m;<\/p>\n

\u2022 Slewing mechanism power: 5.5KW<\/p>\n

\u2022 Trolleying mechanism power: 3.7 KW<\/p>\n

\u2022 Types of tower crane: stationary crane with embedded outriggers, stationary crane with embedded bolts, stationary crane with under-frame and mobile tower crane.<\/p>\n

2. Electrical control system<\/p>\n

With PLC control, the electrical control system enjoys better reliability and safety. Produced by professional manufacturers with advanced foreign technology, the electrical elements feature service lives that are 3 or 4 times longer than that of domestic products, less faults, easy maintenance and repair as well as reliable operation.<\/p>\n

3. Technical features<\/p>\n

\u2022 The crane boasts of multiple operation modes and wide application. The crane can work in different forms: stationary crane with embedded outriggers, stationary crane with under-frame, stationary crane with embedded bolts and crane anchored to wall, thus being applicable to various construction projects.<\/p>\n

\u2022 The complete machine adopts internationally well-received beautiful shape;<\/p>\n

\u2022 The crane features high working speed and excellent speed regulation performance. Stepless speed regulation by frequency control, the world’s most advanced solution, is adopted for the trolleying mechanism and slewing mechanism, thus ensuring more stable and reliable operation ;<\/p>\n

\u2022 The cab is independently installed externally with good vision and large inner space, thus offering a good working environment for operators;<\/p>\n

\u2022 A variety of safety devices are equipped, which are all mechanical or mechatronic products that are applicable to severe working conditions, so as to ensure the tower crane’s reliable operation.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Mast Bolts and Connection Checks<\/h2>\n

Use only the specified bolt diameter, grade, nut and tightening procedure for the approved mast system. Reused fasteners should be accepted only where the manufacturer permits it and after the required inspection.<\/p>\n

Compare other tower crane mast and anchor information<\/a> and send the mast drawing and bolt details<\/a> for matching.<\/p>\n

For site planning, also review the applicable local rules and the HSE lifting-operation guidance<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
