Construction crane

Brief introduction

1. Its performance parameter and technical indicator have reached the lead level in domestic and international advanced level. Its max radius is 56 meters and its max hoisting height 150 meters.
2. Overall size of the tower crane is the pop international style which is very elegant. It is enjoyed by domestic and foreign customers.
3, QTZ40 tower crane has many working versions and widely using in many fields. The machine has such working versions as stationary, attachment etc, which can meet the needs of the constructions of many different objects. The hoisting height of stationary version is 50 meters; the attachment version is based on adding modular and attachment equipments whose max hoisting height can be 150 meters.
4. The working speed of Trolley travel mechanism and Slewing mechanism is high, regulating the speed steadily. The complete set of the mechanism works reliably.
5. Electrical system introducing the international advanced Electrical assembly is used with high automation and convenient operation. Its working life is 3-4 times longer than domestic assembly. It is characterized with few breakdowns, maintenance easy, working reliably.
6. The working mechanism is simply in drive lines, small in size, reliable in operation and convenient in transportation. The Modular tools of the tower crane are made through welding angle iron which is safe and reliable. Every mechanism is compact in structure, advance in technology, complete with all the safety equipments and it is also mechanical or mechatronics products, applicable to bad construction environment which can ensure the tower crane working reliable.
7. The design of the tower crane is trying to adapt advanced mature technology in domestic and abroad based on the situation of countries and principle of safe and reliability to develop the technology level. The adopted technologies are as follows:
7.1 The Electric Assemble applied in our tower crane is manufactured by Professional Electric appliance Factory which introducing the advanced technology from France.
7.2 Introducing foreign advanced technology and domestication equipments such as Weight limiter, Moment limiter, Height Limiter, Amplitude Limiter, Slewing Limiter, swing brake, Traction mechanism brake etc safety equipments in the tower crane.
