After decades of rapid development, China's industrial industrial structure is gradually improving, and key technologies continue to make new breakthroughs, and it has become the world's largest industrial manufacturing country. The use of pendant crane control is becoming more and more extensive, which not only brings convenience to the use of cranes in the industry, but also gradually changes the development of cranes and makes the industry develop better. In the following article I will introduce you to the classification of pendant crane control.
What is pendant crane control?
What is pendant crane control?
A crane is a multi-action hoist that vertically lifts and horizontally carries heavy objects within a certain range. Also known as the crane, aerial crane, crane. The crane is a kind of lifting equipment for loading and unloading goods. It is widely used in the industries of metallurgy, machinery, chemical industry, light industry, electric power, construction, transportation and so on.
The pendant crane control is a controller for cranes that issues motion commands to operate the crane and can control the crane for normal production and life. The pendant crane control refers to a master device that changes the wiring of the main circuit or the control circuit in a predetermined order and changes the resistance value in the circuit to control the starting, speeding, braking, and reversing of the motor. It consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. It is the "decision-making body" that issues commands, that is, completes the coordination and direct operation of the entire computer system.It can be further divided into hoist pendant crane control, rainproof pendant crane control, bridge crane pendant controls and overhead crane pendant control.
l The hoisting machinery used in the bridge construction project can be divided into four categories: light and small lifting equipment, bridge type hoisting machinery and boom type cranes, and cable cranes according to their different structures and performances. Light and small lifting equipment such as: jack, pneumatic hoist, electric hoist, balance hoist (also known as balance hoist), winch and so on. Bridge type lifting equipment such as beam cranes. Boom type cranes such as fixed slewing cranes, tower cranes, truck cranes, tire cranes, crawler cranes, etc. Cable cranes such as elevators.
l According to the nature of lifting: mobile cranes, tower cranes, mast cranes.
l According to the driving method: one type is centralized driving, that is, one motor drives the long drive shaft to drive the active wheels on both sides; the other type is driven separately, that is, the active wheels on both sides are driven by one motor. Medium and small bridge cranes use the "three-in-one" drive method in which the brakes, reducer and electric motor are combined. The common bridge crane with large lifting weight is easy to install and adjust, and the drive unit often adopts universal joint.
l According to the structure: cranes are mainly divided into light and small lifting equipment, bridge type (bridge type, gantry crane), boom type (self-propelled, tower type, door seat type, railway type, floating type, mast type crane) Cable type.
For the type of crane, of course, there is also a corresponding pendant crane control. Different types of pendant crane control are produced according to the type of crane. Different types of pendant crane control are used according to the characteristics of the crane to make the crane more convenient, safe and reasonable to use.
In the future, industrial manufacturing focuses on the development of digitalization, networking, automation and intelligence. We need to maximize the economic and social benefits of the enterprise based on the original manufacturing industry.Pendant crane control really has a lot of advantages and types, you will know the real use experience when you use it.In order to ensure the smooth running of your production work and adequate protection for the operator, you can choose it to control your crane, you will not be disappointed.
