Engineered to be the HDD industry’s ultimate exit-side tool, TONGHAND® by LaValley Industries allows drill rod to be torqued and un-torqued with precision by a single operator from the comfort and safety of the excavator cab.

TONGHAND® eliminates the use of back-breaking wrenches and removes personnel from working in danger zones. It mounts to any brand of excavator—the excavator’s auxiliary hydraulics safely and efficiently power the system.

The telescoping roller arms are used to pick up drill rod and securely lift, tilt, shift, rotate and precisely position a single rod or drill string under the total control of the operator.

The patented TongVise™ easily makes and breaks joints with guaranteed precision. Whether working with drill rod, subs, reamers or other tooling, the TONGHAND® saves you time and money, while improving job-site.
