1. YO18,Y19A,YO20,Y24,Y26 are Hand Held Jack hammer.
2. YT23,YT24,YT26,YT27,YT28,YT29A,MZ7665 are Air leg Jack hammer
This type Jack hammer use compressed air as power, mainly used in construction sites, various types of mines, tunnel, railways, water conservancy construction and national defense construction areas for drilling operations.Suitable for either drilling downward or incline of blast holes in medium-hard rock, of for second blasting operation,Centrally grouped control, nimble starting, stable running and easy maintenance.
YO18,Y19A,YO20,Y24,Y26 hand held jack hammer works without air leg, mainly use for downwards drilling.
YT23,YT24,YT26,YT27,YT28,YT29A,MZ7665 pusher air leg jack hammer always works with support air leg, can be used for any angle drilling.
