Versatility and Power
When the crawler pile driver is drilling, the current of the pile driver's ammeter shall not exceed 100A. If the ammeter current exceeds 100A, the drill pipe should stop and descend slowly, and the rotor always keeps turning. If the current drops below 100 amps and is stable, the drill pipe can continue to decline slowly.

Forging Resilience The Pathway to Strength in Adversity
Second, the use and characteristics of the drilling rig:
1). Use:
Engineering anchoring drill can be used in urban construction, railway, highway, river, hydropower and other projects to drill rock anchor hole, anchor hole, blasting hole, grouting hole and other drilling construction.
2). Features:
1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.

(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
