For the crane, the hook is the key part of carrying all the weight, so it is very important to master the correct use of the hook when using the crane . In general, there are two kinds of sheet hooks and forged hooks that are commonly used to distinguish the hooks according to the method of manufacture. The crane hooks are basically forged hooks, and their toughness is relatively strong. The chip hooks are further divided into single-sided hooks and double-sided hooks. Their carrying capacity and range are different. Now, let's talk with riders about the use of these hooks.

Generally, when the crane truck mounted crane hook during other operations when the hook requirements are very high, make sure the hook surface is relatively smooth, if there is a crack or the like indentation occurred at an acute angle When you need to pay attention. It is important to remember that these cracked and damaged hooks cannot be used for the lifting operation after they have been welded by themselves. It is difficult to estimate the bearing capacity of the damaged hooks. Therefore, such hooks are very dangerous for operation.

Secondly, the load capacity and range of the hook must be paid attention to before using the crane to carry out the work. In general, there will be obvious signs on the hook. If it is not clearly marked, it is necessary to carry out the experiment of static and dynamic load before carrying out the lifting operation. After the experiment, it is ensured that there is no crack or deformation on the hook, and it is determined that there is no problem before the lifting operation can be performed.

Finally, when using the crane hook, it is also necessary to pay attention to the safety equipment, and it is very necessary to install the equipment to prevent the hook from being hooked, otherwise it is very easy to cause safety accidents. Once the surface of the hook has been seriously deformed and worn, it must be scrapped in time and cannot be recycled. These are just some of the things you need to pay attention to when you use the car hook. You can only keep these things in mind during the operation to ensure safety.

HVAC Actuator

Automotive air conditioning (HVAC) actuators are used for damper control to create a comfortable interior environment by changing damper Angle, adjusting supply air temperature, blowing mode, internal circulation, etc. Automatic air conditioning Temperature Control system working principle: automotive Automatic Temperature Control (ATC), commonly known as constant temperature air conditioning system; Once the target temperature is set, the ATC system automatically controls and adjusts the temperature in the car to maintain the set value.
