- Product Description
-
The DB32 multifunctional drilling rig is a new type of electric drilling rig independently developed by Hebei Yongming, featuring the following technical characteristics:
1. The winch and turntable adopt an independent modular design, which is compact, small in size, and convenient for disassembly and transportation.
2. Different models of oil turntables can be optionally equipped, along with matching inertia brakes and roller core supplements.
3. The winch is equipped with an ultra-wide opening drum and a caribou rope groove, which improves the service life of the steel wire rope.
4. The winch is equipped with multiple braking devices, safety protection devices, and an emergency lifting system, and can also achieve automatic drilling.
5. The electrical components of the electric control system use internationally renowned electrical brands, ensuring high reliability.
6. The electric control system has three control modes, which can serve as backups for each other.
7. This drilling rig has various safety protection functions that can be set according to actual working conditions.
Compared with traditional drilling rigs, the advantages of electric drilling rigs are mainly reflected in the following aspects:
1. High transmission efficiency, energy saving.
2. Low failure rate, fewer vulnerable parts, and less maintenance workload.
3. Soft characteristics - stepless speed regulation ensures that the impact generated during startup and speed adjustment is small.
4. Digital centralized control.
5. Work is safe and reliable.
