main features
PT5613 is a fixed tower crane, QTZ63 Tower crane, jack, attached, flat tower crane, the optimization of its parameters through a comprehensive design and reliability design, overall performance of advanced, attractive appearance, with a boom, job coverage, can be Air variable arm length and other characteristics, institutions of advanced performance and parameters, and its design focus on low, medium and high levels of construction projects of various requirements, simple operation, easy maintenance, cost-effective advantages of higher prominence, as a self-elevating and adhesion function, so that greatly increase the height of the tower crane erection, 160 meters to meet the following industrial, commercial, office, civil construction and other construction requirements, for some special applications has more advatages, such as airports, power lines below, and has many tower cranes and construction sites and overlapping work areas. Building construction is the ideal home and abroad handling equipment. This machine has the following main features:
1.1.1 Height of the tower crane is confirmed according to height of building, lifting ability of the tower crane is independent of height;
1.1.2 The tower crane is with feature as high working speed, steady work condition and high effieiency;
1.1.3 Hoisting jib has 56M, 50m, 46m, 40m, 36m, 30m,six ranges which meets projects needs more widely;
1.1.4 Safety devices are complete, the working is reliable;
1.1.5 The eyeshot of cab is well, and the cab is installed independently, which creat preferable working condition for handlers.
1.1.6 Location of the tower crane is reaonable, and the externality of the crane is beatiful.
1.1.7 The operation is simple and the maintenance is convenient.
