DB-3200 drilling rig

DB3200 Electric drive drilling rig
 
DB3200 multifunction drilling rig is a new model of electric drilling rig which is independently researched and developed by Hebei Yongming, has the following technical features: 
1.The winch and rotary table are designed as blocks separately, compact structure, small in size, covenant to disassembly and assembly.
2. Can match different oil rotary table, match inertia brake and roller bushing.
3. Winch matches super wide open seat drum, process the LEBUS rope slot, improved the service life of steel wire rope. 
4. The winch matches several brake equipment, safety protection device, emergency hoisting system and can automatically drill.
5. All the electronic components of electronic control system are adopted international famous brand, high reliability.
6. There are 3 ways of electronic control system, each are reserved for others.
7. There are many kinds of safety protection function, can be set by the working condition.
 
Compared with the traditional drilling rigs, the electric drilling rig has the following advantages,
 
1. High transmission efficiency, save energy.
2. Low failure rate, less vulnerable parts, less maintaining work.
3. Soft character - step less speed regulation guarantee the working equipment generates low impact when starting or regulating rotate speed.
4. Digital centralized control.
5. Work safely and reliably.
