The crane refers to the multi -action lifting machinery of the weight -bearing and the horizontal handling of heavy objects within a certain range, also known as a crane, which we can see in daily life.It is widely used in industry and architecture, so how to choose a crane in architecture?When operating, what are the common sense of the crane, do you know?Lets take a look at the knowledge encyclopedia with the editor.
Introduction to the crane
The crane refers to a multi -action lifting machinery of vertical improvement and horizontal handling of heavy objects within a certain range.Also known as crane.
The main features of tires with heavy machines are: The two of the driving cab and the crane operation room are one, which is evolved from the crawler crane (crawler crane).The crane crane (crawler) crawler board is the disadvantage of damage to the pavement, which is a material handling machine.
The work characteristics of the lifting equipment are intermittent exercise, that is, the corresponding mechanisms that take feeding, transportation, uninstallation and other actions in a working cycle are alternately working, and the development and use of the cranes in the market are becoming more and more extensive.Because some accidents do not need to be lined with legs and heavy driving, the speed of driving is faster than the crawler crane (crawler); the operation is stable, the weight is large, and can be hoisted within a specific range., Tire pressure meets the requirements, and it must not exceed 50cm from the ground; it is forbidden to walk for a long distance between the band load.In order to ensure the safety of operations, it is basically prohibited from lining operations in China.The crane matching uses steel wire rope varieties include phosphorized coating wire rope, galvanized steel wire rope and light surface steel wire rope.
Crane classification
1. Car crane
Installing the crane on the low disk performance on the general or dedicated car chassis is equivalent to the total load vehicle of the same vehicle, which meets the technical requirements of highway vehicles, so it can be unobstructed on various roads.
2, tire heavy machine
The crane is installed on the special inflatable tire chassis.
3. Off -road tires
It is a crane developed in the 1970s. Its weight -bearing function is similar to the tire cranes, and it can also be drove without leggings and driving.
4. A whole ground crane
It is a high -performance product with the characteristics of car cranes and off -road cranes.
5. Special crane
Special crane developed to complete a specific task.
How to buy cranes
1. Material loading and unloading, sporadic lifting, and construction operations that need to enter the market quickly. It is more suitable to choose a car crane.In the hole, the hydraulic car crane is the most ideal hanging machine.
2. When the lifting project requires a crane with a large weight, high installation height, and a large range of changes, you can choose a track or tire crane according to the existing mechanical situation.
3. When the construction conditions are limited, the crane is required to be driving (the driving is dangerous. If it is not operated, the weight of the hanging weight should meet the specifications of the use of the machine), and a crawler or tire crane can be selected.
4. Professional assignments should be selected as much as possible.
5. Try to choose a multi -purpose, efficient, energy -saving crane product. If the construction site needs to hang itself and use a tower crane, you should choose a self -proclaimed tower crane to save the number of machines to invest in the number of mechanical tables.
