Mobile screw ship unloader manufacturers take you to understand the running speed of tire crane

The tyre crane is a kind of lifting machinery which is widely used nowadays. Generally, it is carried out outdoors. The maintenance of the crane is indispensable. It often suffers from wind and rain outside. It is necessary to remove and replace the parts and corrosion parts on time. Electric hoist is a kind of special lifting machinery, which is installed in traveling crane and gantry crane. Electric hoist has the characteristics of light weight, light weight, convenient use and so on.

The rubber tyred crane is used for factories, mining enterprises, warehousing, logistics, ports and other sites. The compressive strength of the jib crane is light. The crane is composed of vertical pole, rotary arm rotary drive equipment and electric hoist. The lower part of the vertical pole is fixed according to the anchor screw. On the basis of concrete, the cycloid pin reducer is used to drive the hanging wall to rotate. The electric hoist operates in parallel lines in the hanging wall I-section steel and hoists the objects.

The cantilever of tyre crane is made of hollow channel steel, which is light in weight, large in span, heavy in lifting, and durable in economic development. The rubber tyred crane has promoted the development trend of the port economic development and improved the operation efficiency. The structure of electric hoist is compact. The center line of motor is vertically divided into the center line of wire rope drum. The electric hoist adopts worm gear transmission. Its defects are: the length of large specifications, the total width of large dimensions, bulky structure, low mechanical efficiency, difficult production and processing.

The hydraulic transmission system of the tire crane is bidirectional operation, overflow regulating valve and magnetic contact barometer can operate the working pressure accurately. Low voltage operation is adopted by the operation unit of household appliances, which improves the safety factor of operation system software. The key to improve the operation speed of the tire crane is to improve the organization, which consists of improving the motor, reducer, wire rope drum, braking system, lifting hook, etc. The lifting motor is connected with the reducer through universal coupling, braking system wheel, and the output shaft of the reducer is connected with the wire rope drum winding galvanized steel wire rope (composed of stainless steel wire, rope core and lubricating grease). The other end of galvanized steel wire rope (composed of stainless steel wire, rope core and lubricating grease) is equipped with lifting hook. When the wire rope drum rotates, the lifting hook will follow the galvanized steel wire The rope (composed of stainless steel wire, rope core and lubricating grease) is raised and lowered by winding or relaxing on the wire rope drum.

Tire crane to improve the organization to improve the motor speed rating than take and put the rate of increase, to m / min as the enterprise. Generally, the increase rate shall not exceed 30m / min, and the decision shall be made according to the characteristics of goods, net weight and increase regulations. Therefore, the operating speed of the crane motor, reducer, wire rope drum, braking system, lifting hook and the lubrication condition of machinery and equipment often have certain harm. The increase in crane speed is also related to the size and net weight of the goods. But I want to remind you that in all cases, safety should be put in the first place.
