Which Size Splitter is Available for Manual Inserting?
In its introductory stage, hand-held splitters are sized and weighed as heavy as 35~40 kgs per each ram. ⌀85 round rods of 800mm length are machined to have 11~12 cylinder slots for pistons. ⌀95 splitters have 9~10 pistons of similar length rods.( See below picture)
Roughly speaking, ram's weight is limited by its maximum of 38~39 kgs. This weight is too heavy for any adult to handle repeatedly.
HRD-tech.com has come up with light and easy set . Its length is maximum 700mm, mostly 650mm . For example 85mm diameter cylinder of 700mm length weighs 30kgs.
95mm diameter cylinder of 540mm weighs 29.8kgs. 30kgs weight is endurable for a strong worker.

High Performance requires longer splitter and heavy duty expanding force.
HRD-tech is suggesting a short cylinder body with lon extended handle for more performance.
For example, we use 95mm x 540mm ( 7 piston) cylinder plus extended handle of 1,080mm . Total length of the splitter is 1,620mm.
Drilling is made upto 2meter deep at a time. The spacing is done with 600mm each.
Continuous inserting after each splitting is recommended in the same hole.
As seen above, splitter length is 540mm only. The first inserting is done upto 540mm in the first round, Then 2nd inserting is done upto 1,080mm point. 3 rd insertion is made to the maximum 1,620mm depth.
By using this simple entedned handle, you can save drilling time. You can drill depth of 1,700mm or so. You insert 3 times instead of moving to other holes. Then total splitting time is saved.
When you use 6 splitters, inserting time plus taking out time is approximately 2 minutes.
Splitting time is within 2 minutes. Instead of 4 minutes splitting for the 540mm depth splitting, you can have 8 minutes for 1,620mm splitting depth.
Likewise, drilling time of 1 meter takes 30seconds Moving the drill rig to next hole spot takes another 15~30 seconds. But if you drill 2 meters, it takes 60 seconds. Moving to next hole takes 15~30 seconds. Total drill time is saved by deep drilling at a time.
We can see details in calculation as follows:
1. 540mm short handle splitter.: drill 1 meter deep, split 540mm deep.
Drilling holes number per hour.
60 min / 1 minute = 60 holes ( 1 meter)
Splitting holes number per hour
60min / 4 min x 6 = 90 holes. ( 540mm )
In summary, Each hole takes 1 minute for drillg, 40 seconds for splitting.
2. 1,620mm long handle splitter: drill 2 meter deep, split 1,620mm deep( 3 times)
Drilling holes number per hour,
60 min / 1.5 minutes = 40 holes ( 2 meter)
Splitting holes number per hour
60min. / 8 min x 6 = 45 holes ( 2 meter)
In summary, each hole takes 1.5 minutes for drilling, and 1.33 minutes for splitting.
As seen from the calculation, short handled splitter breaks rocks of 540mm deep with 1min 40 seconds. Extended handled splitter breaks rocks of 1,620mm deep with 2.83 minutes.
It is evident that extended handle can save lots of work time.
We suggest above method to machine-held splitters too in case of tunnel or quarry sites.
The customer may keep both types of handles for different situations.
Extended handles are good for horizontal drill/splitting. Vertical drill/split method may require extended handles occasionally. Hrd-tech splitters can be attached with short handle or longer handle any time just by loosening or tightening the fixing bolts.
When you keep both types handles, you can use them very conveniently depending on the application sites.
Just look over a typical handles' fixing method from below photos.
extendable rod type handle short handle for 600mm deep splitting.
For machine-held splitters, the extending handles can be shaped like a long round tube.
This is for the easy gripping and releasing the splitter for continuous inserting.
