Henan crane manufacturer's double beam crane speed regulation method. The inertia of the walking mechanism of the double beam crane is greater, which is different from the lifting mechanism. These factors are more likely to cause equipment failures, such as shaft breakage and motor burnout. Therefore, the speed regulation of the crane walking mechanism should be operated with caution. At present, there are four speed regulation methods:

(l) Dual speed motor, mother child motor

The speed regulation method is roughly the same as that of the lifting mechanism.

(2) Soft start, soft brake

In order to reduce the occurrence of electric shock and mechanical shock, voltage reduction starting and electric braking are adopted to achieve the effect of controlling the starting and braking speed, meeting the requirements of use.

(3) Solid core rotor motor

In order to achieve the purpose of soft starting and soft braking, and reduce the occurrence of electrical and mechanical shocks, we can utilize the eddy current effect of the rotor core and the high-frequency current inside the rotor. In general, as long as the appropriate motor power is selected, this operation plan is very effective.

(4) Variable frequency speed regulation

Henan crane manufacturers adhere to the policy of "integrity-based, stable operation" and are brave enough to participate in the healthy competition of the market. We adhere to the principle of "service first, customer first", which has won the trust of numerous customers and established a good corporate image for Henan crane manufacturers in heavy industry.
