What is a winch overload test and what is the overload protection of a large winch

What are the characteristics and uses of dispatching winches? The main characteristics of the dispatching winch are: effective design scheme, compact structure, convenient actual operation, simple maintenance, wide application coverage, and reliable.

Scope of application and application of dispatching winch: The dispatching winch is mainly used in the consignment of minecarts in the coal mine roadway and other auxiliary transportation work, and can also be applied to the mining face and the coal mining layer loading station in the production dispatching team minecar. The main business of Xukuang Mining Machinery and Equipment Company:

Dispatch winch, single speed winch, return column winch, transport winch, rake bucket machine, tension winch, raise winch. Among them, the common models and specifications of dispatching winches are: 3kw dispatching winch, dispatching winch, 25kw dispatching winch, 55kW dispatching winch and 40kW dispatching winch; Buy dispatching winch, dispatching winch wholesale to find Xu Mining Machinery, manufacturers batch....

Hello, I made a pneumatic winch!

Take the 500kg pneumatic winch as an example, 500kg is the rated lifting weight of the winch, and a maximum lifting weight is required when designing, and this weight must be greater than 500kg to ensure the normal and safe operation of the winch! Before the winch is handed over to the customer, it must be subjected to a load test, which is to check its rated tensile force and maximum lifting weight, etc.! The test report of the winch factory needs to indicate what the maximum lifting capacity is, which is the overload weight, so as to facilitate the safe operation of workers!

After the load test is qualified, the overload test is carried out, and the test load is 120% of the rated load. Make at least 3 lifts and drops. Check all parts at the same time, and there should be no abnormal phenomena.

The overload protection of large winches means that when the load of the winch exceeds its rated load, the winch will automatically stop working to avoid damage to the equipment due to overload or safety accidents. Specifically, overload protection usually includes the following aspects of protection:

1.Electronic protection device: Through the installation of electronic devices, the load and speed of the winch and other parameters can be monitored, and when the load exceeds a certain value, the electronic device will automatically cut off the power supply to prevent the further operation of the winch from causing equipment failure or safety accidents.

2.Mechanical protection device: By installing a mechanical device, the load and speed of the winch and other parameters can be detected, and when the load exceeds a vertical dry roll fixed value, the mechanical device will automatically cut off the power supply or loosen the winch to avoid equipment damage or safety accidents.

3.Sensor protection device: the surplus installation sensor can monitor the working status of the winch in real time, and when the load exceeds a certain value, the sensor will automatically send a signal to trigger the stop work protection mechanism of the winch to avoid equipment overload and damage or safety accidents.

In conclusion, the overload protection of large winches is very important, not only to protect the equipment, but also to ensure the safety of the staff. Therefore, when using large winches, it is necessary to strictly follow the operating procedures to ensure the safe operation of the equipment.
