Truck Parts Name?

What is a "wet kit" that I keep reading about?? I see some trucks are equipped with them and others aren't..

This is what I found. wet kit

I never even heard of it!

A Wet Kit is an assembly mounted on the truck that works, or sometimes is, a hydraulic unit. you'll see them on side delivery rock trailers, some harvest haulers who don't have electric chain drive motors that do the floor delivery. But Wet Kits are usually seen on rock trucks, side delivery or rear delivery.

Thanks Ladies..that does clear it up...

Wet Kits (or wetline kits) are kits put into trucks or semi-trucks that have PTO (Power Take Off). Many different accessories are installed on trucks, like booms or cranes, and the kits’ hydraulic pump is activated by the truck's Power Take Off. The accessories need the hydraulic pump to operate.

There are different units in each wet kit. They consist of items such as the hydraulic hose and fittings, reservoirs or tanks, filters, control valves, pumps, and PTOs. Hydraulic fluid is sent through hoses and into cylinders once the PTO initiates the activity of the hydraulic pump. Once the hydraulic fluid gets into the cylinders, the PTO can raise the load or execute any of the other operations that you may desire. The discharged fluid is then returned to the reservoir and, continuing the closed cycle indefinitely, fluid is again sucked by the hydraulic pump.

Dang I learned something new I've always heard of it as a pto system
