What are the types of construction lift keys?

In describing the types of construction lift keys, we are faced with several categories.

Categories that are based on the type of engine, those that are set along the construction technology of the construction lift key, and some categories that are concerned with the working capacity of the types of construction lift keys.

In fact, we try to set up different types of construction lifts in different types of construction lift switches.

Since each piece of equipment comes with a different level of design, it will necessarily require parts with a variety of designs, the category of construction lift keys will be discussed.

 

Classification of construction lift keys based on engine type

You certainly know that electric motors are used to design different types of construction lifts with different capacities. Simple commissioning, low cost, easy changes and the availability of electricity are the general prerequisites for choosing an electric motor.

Since different types of construction lifts are designed in different capacities, it makes sense to need different types of electric motors with different power supply capacities.

For small lifts with low displacement capacity of materials up to 250 kg and sometimes 400 kg, we see the use of single-phase motors in the design of the device.

In order to provide lift power to complete more powerful lifts, we need to use powerful three-phase motors.

Since the starting path to change the direction of rotation in three-phase and single-phase motors is completely different, three-phase lift switches and single-phase lift switches are designed.

 

In the single-phase lift switch, it is supposed to establish the connection path of phase and neutral wires in a principled order.

Note that the change in speed in the operation path of single-phase motors is achieved by moving the phase wire connection next to the neutral wire to the output of the single-phase motor.

The single-phase lift switch is designed in such a way that it can make this connection correctly. But in the design of a three-phase lift switch, the goal is to shift the two phases while connecting the electric motors. The speed of three-phase motors will be shifted by shifting the two phases.

This idea is included in the design of the three-phase lift switch along with all the safety points. Keep in mind that you cannot use a single-phase lift switch or a three-phase lift switch for unrelated motors.

 

 

Classification of types of construction lift switches based on construction technology

 

Lever models are almost familiar examples in the design of construction lift keys. Models that, with the presence of a physical lever, are capable of providing three working modes for the construction hoist motor.

In these classic examples of the construction lift switch, we see the lever in three working positions. Lever design is the first idea in making different types of construction lift switches in both single-phase and three-phase models.

In this idea, by physically installing this key next to the construction lift chassis, the level of control of the device will be provided.

 

But with this idea, our hands will be tied to having a high maneuverability to launch the construction lift as easily as possible, and of course faster and perhaps safer. Because we can only start it from the side of the construction lift.

 

In the new ideas along with the design of the construction lift key, the idea of ​​remote control is introduced.

Therefore, control samples with operating conditions from any point in the construction space are accompanied by the design of various types of construction lift keys.

These types of switches are easily able to be replaced with classic models in the structure of old lifts and can be used without any general need to change the electrical structure of the device.

With the presence of such keys, you can set up a construction lift anywhere in the construction workshop space. This will have a significant impact on improving the security of the device.

 

Classification of construction lift keys based on work capacity

Since we are in the design of various types of construction lifts with different capacities, the issue of using single-phase and three-phase motors will be raised.

Therefore, in the first step to design different types of construction lift switches, it is necessary to design them in three-phase and single-phase operation ideas; But keep in mind that different types of motors with different working capacities, whether single-phase or three-phase, are used to supply different models of construction lifts.

In this case, we need a new classification in the design of the construction lift key based on work capacity.

 

A variety of single-phase construction lift switches are designed in 16 and 25 amp models. These capacities are set at 25 and 40 amps in the design of a three-phase lift switch.

It is logical that a larger number indicates higher power supply conditions. All models are housed in a variety of construction lift switches to provide direct operation of electric motors by connecting a power circuit.

 

Therefore, all the working power in the construction lift will be provided through these keys.

Since more powerful motors need to supply higher currents, the need to match the flow capacity of the construction lift switch with the motor power in the construction lift is quite serious.

Any negligence in the proper selection of the construction lift switch to start the electric motors will be prone to unconventional flow with breakdown and sometimes explosion of the switch.
