Description of TC7021

1) CMAX TC7021 tower crane is one of the key product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.

2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected;

3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.

4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.

5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator

Q:Protective earthing resistance of tower crane
Q:What does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
Q:Tower crane 5610 why call QTZ63 tower crane, 5613 call QTZ806015, call QTZ100
As for the calculation method, the weight of a simple arm length * arm tip can not be used, because the nominal lifting torque of the tower crane is not calculated at the maximum amplitude.However, the maximum weight can be calculated by the maximum amplitude of the maximum weight, such as 5613 tower cranes, the maximum lifting capacity of 6 tons, while the maximum variable distance of 6 tons reached 15m, 60KN * 15m=800KN.m.The above is only my personal understanding of the tower crane, but I am not a professional construction machinery, the above calculations do not know whether it is reasonable, I hope to help you.
Q:What is the allowable range of vertical deviation for tower cranes?
Previous answers to this question have been made. In the industry standard "construction site inspection of machinery and equipment technical specification" (JGJ160-2008), in the form of mandatory provisions: the tower crane installation height to basic design requirements, the axis of the tower line should be no more than 0.4% of the bearing surfaces of the lateral vertical deviation; after the attachment, the highest attachment point following the vertical deviation should be less than 0.2%. "The basic height of the design requirements" in the "strong regulation", that is, the maximum independent installation height on the site".
Q:In order to ensure the stability of tower cranes, generally along the height of the tower and building a number of meters attached
Self lifting tower crane tower 45 meters high to prevail, such as height of over 45 meters, each increased to 10 meters (less than 5 meters, excluding) demolition costs increase 20%, off-site transportation costs increased by 10%.
Q:Tower crane 5610 why is it called QTZ63?
QTZ refers to the lifting tower crane, and the 63 is the torque, the unit is tons x meters, generally in accordance with the crane's nominal gravity moment to sub model, which level is close to which model. The latter four numbers, the first two represent larger, the unit is M, and the latter two represent the largest range of maximum lifting weight, the unit is KN
Q:Tower cranes should stop working when the wind speed is greater than the magnitude.
Rules for safety regulation of tower crane,The installation of tower crane is strictly prohibited at grade 4 or above
Q:What are the working mechanisms and safety devices of tower cranes?
About the structure: Tower cranes are all metal structures, so far there is no wood. About institutions: tower crane working mechanisms are: winding lifting mechanism; luffing mechanism; slewing mechanism; cart moving mechanism; lifting mechanism. A safety device: four limit: height limit, amplitude limit, slewing limit, travel limit; three insurance: luffing rope insurance, car insurance broken shaft, the hook to prevent falling insurance; two limit: torque limiter, weight limiter on these roughly.
Q:What are the main technical parameters of a tower crane?
Generally speaking, the main parameters of the tower crane are:Maximum amplitude unit MMaximum lifting height, unit MMaximum lifting torque unit KN.mMaximum lifting speed unit m/minMaximum lifting unit tRotational speed unit r/minVariable speed unit m/min or o/minWalking speed per unit m/minMotor power unit w......Please refer to the product manual.
Q:Minimum QTZ63 tower crane special electric box open for many A
Tower crane (tower crane) is called tower crane, also known as tower crane, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..
We are a leading manufacturer of a broad range of disposable medical products and durable medical equipments. From 1993, our American Headquarter, Basic Medical Industries Inc. was set up in California USA exploring our initial business of gloves.
