Frequency Control And Braking European Standard Single Girder Overhead Cranes Easy To Use

Introduction:

European single-girder cranes feature light weight, compact structure and low energy consumption. With unique design concept, it has the characteristics of small size, light weight and small wheel pressure.

Compared with traditional cranes, the limit distance from the hook to the wall is the smallest, and the clearance height is the lowest. The European crane can work closer to the front and has a higher lifting height, which actually increases the effective working space of the existing workshop. Due to the characteristics of light weight and small wheel pressure of European cranes, the new workshop can be designed with smaller space and more complete functions. Smaller plants mean considerable savings in initial construction investment, as well as long-term heating, air conditioning and other maintenance costs.

Technical Parameter:

Protection Devices Of European Type Overhead Cranes

Frequency converter: The protection function of the inverter can protect the short-circuit, over-current, motor overheating, under-voltage, over-voltage, grounding, short-circuit, stall prevention, heat sink overheating, and braking unit overheating protection of each driving mechanism.

Distribution protection: The main circuit of crane power distribution is equipped with protective components such as an automatic air switch for the main power supply and main contactor.

Short circuit protection: The main power circuit is equipped with an automatic switch as short-circuit protection of the crane; the control circuit is equipped with a small-capacity automatic air switch as short-circuit protection.

Overload protection: The motors of each mechanism of the crane are equipped with separate overcurrent protection devices as the overload protection; the automatic air switch of the main power supply is used as the overload protection of the crane.

Phase sequence protection: The equipment adopts a phase sequence protector to monitor the quality of the power supply in real time. When the power supply generates overvoltage, undervoltage, phase loss, or phase sequence change due to external reasons, the control system will cut off the main circuit to effectively protect the safety of equipment and personnel.

Lift limit protection: The lifting mechanism is equipped with in-position limit switches and limit switches. The in-position limit switches ensure that the lifting mechanism stops automatically when it is in place. The limit switches can ensure that the lifting mechanism automatically cuts off when the hook up to the limit position.

Travel limit protection: The crane traveling and trolley traversing mechanisms are generally equipped with in-position limit switches and limit switches at both ends.

Emergency power off protection: The control circuit of the crane is equipped with an emergency switch. When an accident occurs, the power supply of the control circuit can be cut off at any time, and then the main circuit is cut off to ensure the safe operation of the crane.

Anticorrosion, dustproof and sealing measures.

Application:

Single-girder bridge cranes have many uses and are widely used in real life. In many factories, many product manufacturers choose cranes for easy handling, and single-girder overhead cranes are more prominent in terms of assisting and transportation.

In addition to general machinery workshops, single-girder overhead cranes are widely used in petroleum and petrochemical, railway construction, civil aviation airports, hydropower plants, ports, papermaking, building materials, metallurgy and other workshops, warehouses, and material yards.
