The Hydracore is one of the most versatile machines for core drilling. It is ideal for drilling N size holes to about feet, but it can also drill H size to . Hydracore News. Stay up to date with the latest Hydracore News. . We are building three Manportable drills, two Hydracore s, and one Gopher top drive. The Hydracore is a light weight (lb/pick) diamond drill that can be used in skid mount and heliportable operations. This rig is designed for modular.

In October I took a trip to Ecuador and to Chile.
Ecuador is a very beautiful country. One difficulty was that this machine will […]. The low speed mode is really equivalent to 2nd gear hydraacore other similar sized drills. This machine is to be used mainly for environmental drilling around Greater Vancouver.
This month I have added a few links on our site to other companies who are our yhdracore distributors. This chuck is deceptively strong though. In practice this lack of torque does not end up being detrimental at all.
This month we are not very busy so we are building a machine for stock. On the specification sheet for a Hydracore the torque in low speed mode is not as high as with some other drills like a Longyear LF 70 for example. If you look at the drill bit size chart you will also find a drill rod size chart. Drill Rod and Bit Charts These charts have information that you cannot find anywhere else, about drill bit sizes, drill rod sizes, and constants that can be used to figure out drill bit and hydracote rod torque.
Usually drillers discover this limit by breaking off a rod string.
We have sold two heads with this new chuck […] More. Hydraore I went to Chile to see Expert Drilling. The Hydracore Underground uses many of the same components as the Hydracore surface drill. The frictional drag is assumed to be proportional to the weight of the rod times the radius of the dragging surface of the rod.
Like everyone in core drilling we slowed right down in and it seems like this slow pace is going to continue for a while longer. Not only is this new chuck strong, but it is also simple and durable.
Hydracore 2000 Underground
The Hydracore Gopher was the original manportable drill. The Hydracore Underground is a bit more powerful than the Hydracore Underground. A unique cylinder is used that is better than what other suppliers have.
It may be that the Link Chuck is actually stronger than the Nitro Chuck! Most drillers barely pay any attention to any numbers at all except maybe the number on their paycheque.
I guess this new chuck is pretty unimpressive looking on the outside. It can be made with a gasoline or diesel engine of 30 or 40 HP, and is capable of feet B or feet of N. This chart predicts that the bit torque for an AO bit would be half what is required for a BO bit. No one pays much attention to what the maximum amount of torque a drill rod string can take is.
This sometimes makes our machines seem to appear inadequate on paper. I think it is the best little underground drill on the […] More. There is also a hyxracore for depth capacity of Hydracore drills. That is pretty good, but I have seen our Link Chuck holding 33, lbs.
Hydracore Manportable – Hydracore Drills
It is certainly a lot simpler. Often the drag from the drill string can be cut in half just by greasing the rods, but this chart may perhaps give an idea of the amount of drag from different rod sizes.
Stay up to date with the latest Hydracore News. BC Hydro used it to drill anchor bolt holes for transmission […] More. BC Hydro used it to drill hydracire bolt holes for transmission […]. I no longer have […] More. We want to keep the company the same, because […] More. The rod pulling device in the picture is mainly made of typical Hydracore parts.
More torque is available in reverse for rod breaking, because the reverse pressure is set at the hydradore pressure of the system of 5, psi and the maximum pressure in forward is only 3, psi. The assumption is that the force on the bit would be in proportion to the area of the bit in that way the torque to turn the bit would be effected by the bit area, and the diameter of the bit.
The hydraulic powerpack also uses mostly the same components. The diameter 2000 to calculate the torque constant is the diameter mid-way between the outside, and hyvracore of the kerf of the bit. On a machine like a Hydracore with a variable displacement motor or many other machines with gear boxes, the only way to get this extra torque is to slow the rotation speed down, either by gearing down or increasing the motor displacement.
It is enough torque to easily wreck anything less than P size. In February we built a special rod puller for AMC mining. Drillers like using it. Au Com solid state soft start, with ground fault protection, and hydrzcore KVA transformer. No parts have yet required replacement, not even the jaws.
Some customers have drilled feet of N in very inaccessible sites with these machines. It looks a lot like a normal auto chuck. We have only built two of these drills before, but we have used many of the components for quite a few years.
