As the name implies, without affecting the function of the excavator, the excavator can be transformed into a hydraulic rock drilling rig, down-the-hole drilling rig, or spiral drilling rig by using the excavator's own breaker oil circuit, connecting a special hydraulic conversion device, and removing the bucket.

[pdf] This block is a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the sheaves on the crown and through the sheaves in the traveling block. This provides a significant mechanical advantage to the drill line, enabling it to lift heavy loads of pipe and casing. The. .
The size of the groove should be the same as the diameter of the drilling line to deliver the proper support. A tiny pulley groove could cause high friction. Furthermore, it can cause. .
Periodic inspections: The Rig Traveling Block, as with all Hoisting equipment, must be inspected according to the manufacturer’s recommendations and API RP 8B or related ISO (International.
