Third, the tower structure rotation mode

Can be divided into the rotation ( rotating tower ) and turn on the ( non-rotating tower ) tower crane .
Slewing tower crane will lower slewing , etc. counterweight disposed in the lower end of the main body , and its advantages are: tower suffered few moments , low center of gravity , good stability, electrics tacker installation and maintenance , the disadvantage is more demanding slewing high mounting height is restricted.
Slewing tower crane on the slewing ring , a counterweight , major institutions are set at the upper end , the advantage is due to the tower does not turn , simplifies the tower substructure , lifting plus festival convenient. Disadvantages are: When the building over the tower height , due to the impact of the balance arm to limit the rotation of the tower crane , while the higher center of gravity , air pressure increases, the pressure weight increased , so that the total weight of the machine increases.
Fourth, the crane installed in different ways
Be able to be folded into transport, the overall self- erecting tower crane for quick installation and requires the use of auxiliary equipment for group fight and dismantling of tower cranes .
Able to set up their own fast -loading machines are small and medium under the tower slewing cranes , mainly for short duration, requiring frequent movement of low-rise buildings , the main advantage is to improve work efficiency , saving installation costs , saving time and labor and material , the disadvantage is complex structure, the amount of maintenance .
Subject auxiliary dismantling tower crane is mainly used in high-rise buildings and a large range of work , lifting a large quantity of places, is the construction site of the main types .
Five , according to whether the structure of the spire
Can be divided into flat and Pallet stackers tower crane tower crane .
Flat top tower crane is developed in recent years a new type of tower crane , which is characterized in the original jack-up tower crane structure before and after the abolition of the spire and its rod section boom enhances the structural strength and balance arm , arm and balance arm is directly connected , its advantages are: 1 , the whole small , easy to install safety, reduce transportation and storage costs ; 2 , boom tolerated good performance , force uniform, and connecting parts of the structure damage to the small ; 3 , part design standardized, modular , interchangeable , reduce equipment idle , improve investment efficiency , the drawback is the same type of tower crane tower crane Zhongping head slightly higher price .

Tire crane hoisting mechanism manipulation

This article explains the tire crane hoisting mechanism operating essentials , and precautions
Hoisting mechanism manipulation
  Agencies designate vertical ( pull switch in the " machinery " position ) ;
  ( A ) cargo powered palle ttruck . Lifting the handle will pull to the "up" position, release the brake drum pedal controls the lifting speed . Observe the lifting motor current value when the current is less than ll oA can continuous operation ; current exceeds lloA (Jm: <155A) , the starting time should be 71 Ding an operating cycle time of 15%.
    ( 2 ) the goods stay in the air . Release the accelerator pedal , the brake pedal depressed reel and levers in place. If the goods need to be in the air longer stay , you also need to pull the switch in the " Electric" position to ensure safety.
    ( 3 ) gravity drop. Lifting the handle in the neutral position . Jane brake pedal controls the volume . Lifting lowering speed shall not exceed 1.5 times the speed . Work process in order to avoid danger .
    Electrically operated ( pull switch in the " Electric" position ) ;
    ( A ) cargo Pallet stackers . Loosen the drum brake pedal , pull the handle to the frame lifting "up" position tube , feet stepped on the accelerator pedal to control the lifting speed . Precautions with the " mechanical " manipulation.
    ( 2 ) the goods stay in the air . Release the accelerator pedal , the lifting levers in place, if the goods are to be in the air for a long stay , you can simply roll the brake pedal depressed , to ensure safety.

Tire crane slewing manipulation

This paper describes the tire as long as the crane scissor pallet truck maneuvering requirements and considerations
Rotary control
(1) Release the rotating brake pedal, the handle is turned to the desired position ("left" or "nails">, gradually increasing the rotational speed of the throttle control.
     (2) then the levers in situ, the turntable in a free state
When the rotating part of the crane in the parking brake smoothly.
     (3) rotary manipulation essentials.
     1) can be changed brake by the normally open normally closed, that the brake pedal while stepping on a tooth bit immobile (determining that a braking torque). Experienced drivers can pull the handle to the original position in advance, so that the turntable with inertial stop after a journey through to the desired determine the location, without having to depress the brake pedal again.
     2) Zhao heavy machinery driving, do not move Pallet stackers must be trampled to death. Turntable front with anti-rotation device, if necessary, can be locked to ensure driving safety turntable, but had to pull out before the rotary control latch.
     3) To enable a smooth swing operation room will make the crane turntable is level. And should not be rapid rotation. General Requirements: 6t more goods from turning when the maximum lifting rope declination <3. Master lifting 6-3t cargo slewing, lifting rope maximum declination <6 degrees rotation when lifting 3t the following goods, lifting the maximum angle rope <10. .

Crane working operation precautions

Therefore, in the run-in period is likely to cause Crane parts (especially the mating surface) wear, wear faster. At this time, if the overload operation, it may cause damage to parts that Crane produced early failure.1): Understanding lifting cargo size, central location to find cargo crane column distance from the center, according to the lifting capacity of the crane from the view parameters.

2): Crane lifting capacity (torque) is fixed, the larger crane working radius. Lifting cargo lighter, smaller working radius, lifting heavier cargo. (Working radius refers to the moment of the horizontal distance center to the hook.) -

3): Consider the size of the crane lifting capacity of the chassis size, the larger the better beam is selected, crane big and small chassis, will beam deformation and fracture. Small chassis, engine power is small, the impact of the lifting capacity of the crane. Therefore, we consider the beam 230mm, you choose the 3 tons crane. When considering the beam 250mm, consider the following six tons crane. 280mm girders can select one of eight tons crane. Like the previous four after eight chassis can be considered under 10 tons crane.

in order to produce high-end products, such as nuclear ring cranes, large weight

Crane manufacturing industry is closely related to urban construction, transportation, energy development and other people's livelihood cause of the industry. In recent years, China's crane industry has achieved rapid development. To bridge gantry crane manufacturing company, for example, to 2008, China's bridge gantry crane has about 450 manufacturing enterprises, employing over 14 million people [1]. If these enterprises are divided into three echelons: big play, too heavy in the first echelon, they are the industry's largest economy enterprises, with national technical center, comprehensive strength, in order to produce high-end products, such as nuclear ring cranes, large weight metallurgical cranes, foundry cranes, large dock cranes, etc.; second tier that includes Weihua Group, including China's top 20 companies, most of them have plant-level technology center, which is the establishment of Weihua Group regional technology center in Shanghai set up a product design and Research Institute, these enterprises are the backbone of the industry, products cover a wide range of high-end Pallet stackers both in bidding, also participated in the competition from cheap generic products; third echelon is the remaining four hundred SMEs, which generally are small, roughly the same product type, and to be priced competitively based market share effective strategies to enable these enterprises generally poor, severely hampered the pace of development
the inspection of the overhead traveling crane pulley. Focus on the bottom wear is excessive and cast iron pulleys for cracks. For institutions pulley overlooking Yang balance wheel, because it does not operate normal conditions, it is easily overlooked. So, be sure to check before installation flexibility of its rotation, otherwise, the installation length of rope around overlooking Yang and tension can not balance wheel to automatically adjust, so that an increase in the height adjustment overlooking Yang rope and operational risk level of difficulty.
