What Is A "Wedge Type Structure" For Hydraulic Expansion In A Decoiler?
Decoiler Expansion: Manual or Hydraulic?
When talking about decoilers, the loading capacity of decoilers is very important. One of the factors that affects decoilers' loading capacity, is the expansion capacity. Manufactures of decoilers usually adopt 2 different expansion methods, taking into consideration the weight of the coils. When the coil is less than 2 tons, manual expansion is oftenly used. When the coil is over 2 tons, it's better to use hydraulic expansion for the decoilers. See pictures below to understand the difference.
2 Different Types of Decoiler Expansion Structures
Moreover, for hydraulic expansion, there are 2 different types of structures.
One type is "pull rod structure" expansion. And the other type is "wedge type structure" expansion. See pictures of decoilers below for the difference:
Usually, when loading capacity is high, we use "wedge type structure" expansion for the decoilers. When loading capacity is less, we use "pull-rod structure" expansion for the decoilers. The difference for these two structures, is that the decoilers using "wedge type structure" expansion is much stronger than decoilers using "pull-rod structure" expansion. Thus, the "wedge type structure" expansion decoilers has a longer service life than "pull-rod structure" expansion decoilers.
How To Select A Good Decoiler Supplier: See Into The Details
When we sit in front of many offers from different suppliers, we get confused why the prices are so different, but the parameters are so similar. Well, the differences are in details like this. Some suppliers design their machines to be used for 1 year, some others design their machines to serve for at least 10 years.
HongEr Machine honorly choose to be the latter.
