Shandong Zeyu Steel Products Co. Ltd mainly produces tower crane and construction hoist, products are divided into: QTZ40, QTZ45, QTZ50, QTZ60, QTZ63, QTZ80, QTZ100, QTZ125, QTZ160, SC200/200 construction elevator ten series of more than and 20 models. Company to "science and technology" concept and actively introduce advanced technology at home and abroad, the broad strokes of high level talents in science and technology, using the latest production technology and strict detection means, the product structure is more reasonable, more reliable performance, Ze Yu Jian machine famous China, the majority of users at home and abroad by the Qing mei.

QTZ60 (TC5010) tower crane is made full use of grouped technology, combination of design technology and finite element analysis technology, with the "tower crane design platform" as the tool, designing the latest domestic lifting transport machinery.

The machine is a horizontal arm frame, the car changes in the range of the rotary hydraulic jack crane, the maximum lifting weight is 600kN, the maximum lifting torque is M. - 5T

（1）Performance parameters and technical indicators have reached the leading domestic, international advanced level, the maximum working range of 50 meters, increasing the work space of the tower crane.

    (2) the overall shape of the whole machine is an international popular form, which is beautiful and generous.

    （3) It has a lot ways of working, and it is used widely. There are two kinds of working methods, it is suitable for various construction objects; the independent lifting height is 33.8 m, the attachment height magnification is 119 m, the four magnification is 60 meters.

    (4) the working speed is high, the speed control performance is good, the work is stable, the efficiency is high.Hoisting mechanism with three speed motor and single speed ratio reducer, to achieve heavy load and low speed, light load and high speed, the maximum speed of up to 68m/min.

Trolley mechanism tractors in the horizontal arm  luffing, which has good installation position.

Slewing mechanism adopts winding motor with planetary gear reducer, hydraulic coupling, bearing capacity, stable starting, reliable operation and function with wind in place.

     (5) all kinds of safety devices are complete and can be guaranteed to work safely and reliably.    （6）Independent side of the driver's room, the field of vision is good, to create a good working environment for the operator.

    （7）simple use and easy maintenance.

The machine independent operating state steel weight (excluding counterweight, foundation, agency)is 21.39t, The total installed capacity of 32.2kW,Widely used in high-rise hotels, residential, industrial and other construction projects, It is the ideal building construction machinery for the majority of small and medium construction enterprises.
