Greenhouse Hand Crank Application

In greenhouse applications, a hand-crank reeler is typically used to roll up or deploy the greenhouse film (the plastic sheeting used for covering the structure). This is especially useful when you need to open or close a greenhouse for temperature and humidity control or when you want to replace or clean the film periodically.

Here’s how the hand-crank reeler might be used:
