Our Tools in your hands, get jobs done!



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. TONGHAND® mounts to any brand of excavator—the excavator’s auxiliary hydraulics safely and efficiently power the TONGHAND® system.

The TONGHAND®’s 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.



Basic Features:

  • TONGHAND® mounts to any brand of excavator in the 30-36 metric ton class.
  • Patented TONGVISE makes and breaks joints up to 120,000-foot pounds of torque.
  • Works with pipe reamers and adapter sub connections ranging from 6.5” to 10”.
  • Patented Roller Arms and shift function allow you to thread and unthread all connections.
  • Gull Wing design allows you to easily move arms out of way to make and break reamers.
  • Tilt function allows up to 20° of tilt in both directions.
  • Shift feature allows the pipe to be shifted a total of 7”
  • TONGHAND® can work as a pipe handler for precise placement of drill rod on rigs, racks or trucks.
  • TONGHAND® control system and In-Cab display allows you to torque pipe joints to your specified torque value.


Delivering unparalleled speed, precision, and performance, the TONGHAND® is as safe as it is agile. Out-performs all existing material handling methods.
