Why the keys of modern excavators are universal

I think there are two reasons:

1. The excavator is too large and too slow, so I don't worry about being stolen; 2. The excavator can only be constructed on a fixed construction site, and the operator must be able to prove the qualification of the owner or user.

There is a GPS under the excavator base, on the surface or behind it, which is used for global positioning Even if your excavator is stolen, as long as it is locked by GPS, he can't turn on the machine and can't move, so he can only steal and can't use it, and it's useless to steal It is useless to sell scrap iron Hehe.

The keys of the general excavator are universal, so only you can change the lock yourself.

This is an international product safety issue, to solve their own excavator to be able to change the lock.

Modern companies are not going to change

Komatsu, Hitachi, Carter, Kato's keys are all universal, and the repairmen in the repair shop each have several kinds of excavator keys to facilitate the test operation.

My home appliance key kills all brands of excavators and the physical test can also be started.

Anyway, I know Kubota doesn't ...... like thatLovol's can !!

If you want me to say that you are not right ... The key is that manufacturers in order to reduce costs...

You need a similar key number, but you don't know how to start

Most of them can be used universally. However, some models are still not universal. You can go to Shanghai Zhonglian second-hand excavator market to see this.

Hyundai 60-7 excavator key this can not be universal.

This one is certainly not universal. Hope mine can help you.

Not afraid to steal, and few people steal. The cost performance is too low, it is not easy to shoot, it is slow, and it is not easy to drive. I've found that the keys to many types of things are universal. For example, there seem to be only four keys on the train.

I'm not afraid to steal, such a large thing, I was caught stealing it in less than a morning, and there is no point in stealing.

Because excavators are universal keyholes, many excavators are common technologies. Now the mining machine has an identification code on the main engine like a car, and it will also have its own ID card when it is purchased, and it will be bound to the name of an individual or a company. So I'm not afraid of being stolen, and if I do, I can get it back quickly!

B: battery;

BR: battery relay;

R1, R2: resistance (preheated resistance wire);

C: Start (in fact, it is connected to the starting motor relay);

ACC: Flameout (in fact, there is a start-out controller and a flame-out motor relay connected).

The key has four gears, the key gear: the gear just plugged in is OFF shutdown, the first gear clockwise is ON power-on, and then the one gear screwed clockwise is start, and the counterclockwise gear screwed after the key is inserted is preheat preheating.

This is the number of terminals on the start switch, which is the mark of the terminal, which controls the connection, disconnection, preheating, and start through the combination of each terminal.

When the warm-up function is performed, R1 and BR are turned on.

The turn-on position is ACC and BR on.

At startup, R2 and BR are turned on.

When it is disconnected, there is no connection between the terminals.

When the key is in the ON position, let go of the hand, the key will also remain in place, if you let go of the hand in the ignition and preheating position, the key will automatically return due to the elastic force of the spring.

The same type of equipment of construction machinery is universal, and the accessories company is only 10 yuan each! There are also special, mostly generic!
