The pendant crane control has the characteristics of beautiful appearance and reasonable structure. Secondly, it has high mechanical strength, collision resistance, and has an emergency stop switch and mechanical interlock, which is safe and reliable. The contact capacity is large, the service life is long, and the one-handed operation is convenient and convenient. I will give you a detailed introduction below.
You will know:
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.
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.
According to the nature of lifting: mobile cranes, tower cranes, mast cranes.
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.
According to the structure: cranes are mainly divided into light and small lifting equipment, bridge type, boom type 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.
The pendant crane control is a product developed by drawing on the strengths of similar products at home and abroad. Its plastic shell is beautiful, sturdy, lightweight, and reasonable in structure; Make the product safer and more reliable; control button station formed by different buttons. The performance reaches IP65 level; it has good anti-rain performance, so pendant crane control is used in rainy days, open air, snowy days, and dusty harsh environments and hand wet operation sites. This product provides a good control button for remote control of automation equipment. Widely used in cranes, electric hoists and other equipment control.
The control button is a combination of a housing, an emergency stop switch and a multi-button switch. The outer casing is injection molded from ABS plastic. The button head uses a clear directional indicator that is not easily worn. The contacts are made of standard silver contacts for good electrical conductivity. The emergency stop switch needs to be rotated or fingered to reset, and the operation button is automatically reset.
