Description of our Tower Crane

The tower crane is a combination of advanced technologies of the present day. The electric control system of the tower crane adopts the advanced “PLC + frequency converter” control mode of the present day, which has realized the stepless speed regulation and greatly improves the reliability, maneuverability and stability of the control system and the work efficiency of the tower crane.

The tower crane is equipped with all kinds of reliable safety devices, such as hoisting height limiter, slewing range limiter and multifunctional limiter to control the load moment, hoisting capacity and trolley traveling range. Its PLC (Programmable Logic Controller) unit can diagnose the cause of breakdowns. Its Safety Monitoring System (also known as Black Box) displays the data of working radiuses, heights, moments and weights.

The use of world-famous electric components such as OMRON, YASKAWA, Schneider (TE) and MEAN WELL greatly reduces the failure rate of the electric control system and improves the work efficiency of the users.

Besides, there are also electric safety devices like anemoscopes and obstacle lights and mechanical safety devices to prevent the breaking of trolley axles and wireropes. 

Advantage of our tower crane
1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.
2, suitable for the group of tower cross homework.
3, boom stability is good, combination amplitude range.
4, suitable for height have special requirements occasions construction.
5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

Q:What's the difference between QTZ63 and qtz630, isn't it the same kind of tower crane?
It's the same kind of tower crane, but it's only a unit of rated lifting torque. The former unit is 63 tons. M, the latter is 630 kn m. According to the latest national standard "tower crane", GB/T5031-2008 and QTZ63 are written correctly.
Q:Can the tower crane personnel install the construction elevator?
As for the hoisting equipment, the licensed crane erection worker can install the construction elevator.
Q:Is it difficult to test tower cranes?
See the ability of individuals, the first ticket 650 yuan graduation card ID card (copy) medical certificate according to 3 inch 3 days learning theory exam two days of practice examination through 15 days notice thank you hope to adopt licensing
Q:What is the safe distance of a tower crane to the surrounding buildings?
JGJ160-2008 "construction site mechanical equipment inspection technical regulations" on the 46 page clearly written, safety distance shall not be less than 0.6 meters,
Q:What are the safety devices for tower cranes?
(6) the rail clamp is used to clamp the rail, prevent the crane from walking by wind in the strong wind, and cause the tower crane to derail and overturn the accident.(7) the wind meter automatically records the wind speed, and automatically alarms when more than six wind speed is over.(8) the anti stripping device of the steel wire rope is mainly used to prevent the steel wire rope from disengaging from the pulley groove during the transmission process(9) the hook insurance prevents the lifting of the steel wire rope because of the excessive angle or the wrong hook, and causes the lifting wire rope to be broken off and the suspension falling accident.
Q:Construction tower crane driver (T) Ben can be used as construction crane driver (S)?
Building crane driver (T); tower crane driverConstruction crane drivers (S); construction elevator drivers; neither is common.
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..
Q:What courses should I take to buy the tower crane to be installed?
First in the construction, some costs incurred during the installation, after installation costs together included in the original value of fixed assets.
Q:How to choose tower crane in engineering, such as arm length and lifting weight?
1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.
Q:Lifting tower crane tower more than 45 meters, the demolition cost and how to adjust the field Sinotrans transportation fees?
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%.
