The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for315Kn.m;the maximum hoisting load of 3t and the maximum working radius of 39m.The hoisting height of anchoring tower crane is 25m and that of climbing tower crane is 100m.
The tower crane has ingenious design, beautiful shape and simple structure .It is easy to operate and maintain, and is safe and at a reasonable price .It is an ideal construction machines for construction enterprises. It has hoisting mechanism, swing mechanism, top-rising mechanism and radius mechanism, which can work individually or cooperatively to make a high efficiency. The top-rising mechanism is used to raise or lower tower. The hoisting mechanism has 3-speed electronic motor respectively for high, medium and slow hoisting speeds. It has flexible swing mechanism and radius mechanism and slewing mechanism for vertical and /or horizontal transportation of building materials in one time.
The tower crane has complete and sensitive protection devices such as hoisting weight limiter, hoisting moment limiter, hoisting height limiter, radius limiter and swing limiter to ensure of regular operation. It also has rest platform, guardrail and other protection devices. Driver’s cab is at a side of rib and has big space and wide visual field.
The tower crane has excellent performance and is suitable for hoisting in short civil or industrial buildings or loading or unloading in ports or goods yards
