Product Description
                             DF-Y-5 mining used borehole core drilling machine
Product Introduction
The machine is fit for engineering works of inclined and vertical hole drilling. It is compact in construction,
rational in overall arrangement, moderate in weight, convenient in assembling and wide in range of 
rotation speed. Equipped  with water brake, with high hoisting force, DF-Y-5 is convenient to operate in low-position and with water brake application.
Strature Details
1. There are more speed grade (8 grades), reasonable speed range, with low speed but high torque. 
The rig is adapted for core drilling with tongalley~carbide~tipped and diamond bit, as well as suitable for engineering geological exploration, hydrological well drilling and basic pile engineering.
2. With large spindle I.D. 93mm (3.66 inch), the rig is fed with hydraulic double cylinders with much longer stroke up to 500mm(19.69 inch).With strong technological adaptability, the rig can be adapted on many field, especially on large diameter drill rod drilling, with wire line coring (upper part coring). Thus it is more effective in improving drilling efficiency with less faulty in hole. 
3. With powerful drilling capacity, the rated drilling depth comes up to 1,300m(4,264 feet) with 71mm(2.80
 inch) drill rod with wire line coring.
4. Light in weight, the rig can be dismantled into 10 parts easily (the biggest one 450kg equivalent to 
992 lb). The rig weighs 3,100 kg(6836 lb) (without power unit). It can be moved easily especially in 
mountain area.
5. Supplying oil with a single~gear pump, it is easy for installation and application; lower in consumption of energy and a low temperature of hydraulic system oil; the rig is for sure in steady drilling. The hand 
oil pump may be used to hoist the drilling tools in hole upon the faulty of power engine.

Max. Lifting Capacity of Spindle135 kN (30348 lbf)
Max. Lifting Force(single line)60 kN (13488 lbf)
Dimensions 3700*1300*2175 mm (with diesel engine)
 Weight of the Rig (without power unit)3,600 kg(6836 lb)

Key Points To Buy
In order to order the suitable product,firstly you need to make sure the following details:
1. Application: What kinds of projects you will work for,Water well,Borehole,Exploration coring,Foundation
Piling or others?
2. Drilling depth: The Max. depth of drilling you hope to achieve?
3. Drilling Caliber: The Min. and Max. hole diameter you estimate?
4. Stratum: Condition of the environment, Soft ground like soil,mud,Hard ground like rocks or Mixed the
soft and hard layers?
