SERIES 2i

Introduction to Kinghitter S2i

The Kinghitter S2i features an all-new Hydraulics System, where traditional thinking has been set aside in view of high efficiency and usability. The S2i recycles the oil dumped during the hammer drop within its own hydraulics system, eliminating the need for a high flow dump line. This makes it perfect for specialist applications such as with excavators and skidsteers, as it can be operated from two 1/2” auxilary lines, and with quick release couplings. This also makes interchanging the postdriver from one machine to the next an absolute breeze. “i” is for interchangeable.

Based on the Series 2, it shares the same 150UC Mast made from premium 350 Grade Steel, and is compatable with the entire range of Series 2 Bases and accessories.

The Challenge

On a standard post driver, the hammer falls, retracting the lift ram, pushing all the oil within the ram back into the tank of the tractor. A standard hose and 1/2” quick coupling cannot handle this much oil, as it would restrict the fall of the hammer. We aimed to develop a hydraulic system that removed the need for this high flow dump, so that the post driver could be plumbed with standard 1/2” QRC’s, and have no restriction on the hammer fall.

The Solution

The team at Kinghitter devised an ingenious hydraulics system, which utilises a double-acting hydraulic lift ram and a new system of valves. When the hammer drops, the oil used to lift the hammer is recycled back within the system, eliminating the rush of oil back to the tractor and removing the need for a high flow dump line.

The new system of valves control the dump of the oil so that it is always matched to the speed of the freefalling hammer. This means that the rope stays tensioned, which eliminates rope “whip”, shortening the cycle time between hits and increasing rope life. Fast cycle times gives operators a fast, safe and easy to use high performing post rammer that will simply get fences built faster.
