| The maximum length of its jib can be 60m and can be reassembled to 55m, 50m, 45m and 40m, which can have a wide work range spite of barriers. The anchoring tower crane has the hoist height of 46.2m. The tower crane can use fluid drive system to increase or decrease mast height so as to make proper crane height for different building height. the climbing tower crane has the hoist height of 161m. At specific requirement and through special treatment, the anchoring tower crane can have the hoist height of 51.2m and the climbing one can have the hoist height of 200m. The tower crane has horizontal jib and double trolley traveling length, .Load hangs to trolley and changes working radius with the traveling of trolley on jib. When changing speed, steel rope can hang only one trolley so as to lighten the tower crane and hang more loads. Co***red with jib-moving tower crane, the crane is more stable, easier to install and has a wider working radius. And building materials can be in a wide range. The tower crane has complete safe devices such as hoist height limiter, trolley traveling limiter, hoist moment limiter, hoist load limiter and tower crane rotating limiter. All these devices are sensitive and reliable. All devices have arresters for safe working. Its driver room is very comfortable and has big ***ce and goog visual field. The electric control system and all parts have good performances, are easy to buy and repair. |
