Specification

Max. Pile Diameter:

2300 mm

Operating Weight:

100 T

Max. Pile Depth:

94/61 m

SR285 rotary drilling rig is a classic model features with high efficiency, low fuel consumption, smart and flexible, suitable for hard soil drilling, cast-in-place pile foundation work in civil engineering.

High drilling capacity

SANY Kelly bar is made of high strength steel tubes with light design. Maximum output torque reaches 285kN.m, maximum pile depth of friction Kelly is 93.5m, pile depth of interlocking Kelly is 61m.

New design of main winch delivers faster line speed of 70m/min, bigger lifting power with 330kN line pull.

Safe and reliable

The 5th generation rotary drive adopts multi-gear control, self-adaptive techniques, and double buffering system which can increase drilling efficiency and safety.

SANY-ADMS intelligent operation system, advanced hydraulic system and heavy wide chassis ensure efficient, safe and stable operation.

Advanced welding robots, CNC automatic cutting machines ensure high precision and quality of the core components.

Easy to transport&operate

Compact in transport height and weight, the drilling rig is easy to transport in cities.

The tailored chassis with larger spaces for pumps and valves is for easy maintenance during work.

Q: Which is better, wheel driven pile driver or caterpillar rotary drilling rig? What's the difference between workmanship?: Wheeled come and go convenience, crawler effect is better!

Q: There are also some related costs. Originally wanted to buy a pile driver, the budget of 100-200. I hope my friends will give me some advice.. Thank you: Depends on what project you do, if there is no noise requirements, diesel hammer piling machine is better, a price at about 500000, back to Ben faster. The hydrostatic press is a bit heavy.

Q: What's the difference between a walking tube type diesel pile driver and a track type diesel pile driver?: The piling machine works on the top and bottom of the pile hammer. The pile hammer moves up and down on the 2 rail. It is called a track type diesel pile driver, and the pile hammer operates in the pipe way up and down. It is called a tube type diesel pile driver

Q: Requirements of waveform guardrail column piling skills training program and training program.: B, anti blocking blocks, wave beam, end installation(a) after installing the upright column, the bracket (block block) can be installed. The bracket (stop block) is fixed between the wave beam and the upright post through the connecting bolt. The bracket (block) shall be adjusted to make it in place before tightening the connecting bolts.(b) the wave beam is spliced with each other by a splicing bolt and is fixed by a connecting bolt bracket (an anti blocking block), and the direction of the overlap of the roadbed guardrail and the corrugated beam is the key of the installation, and the installation is carried out in strict accordance with the drawing. The direction of overlap shall be consistent with the driving direction. The wave beam should be adjusted continuously during the installation. Therefore, the connecting bolts and the splicing bolts should not be tightened too early so that the long holes in the corrugated beam can be adjusted in time during the installation process so as to form a smooth alignment and avoid local irregularities. When the alignment of the guardrail is considered satisfactory, the bolt can be screwed at last. The connecting bolt between the bracket (stop block) and the wave beam should not be screwed too tight, so that the temperature stress can be adjusted by using a long round hole.(c) the end beam is spliced with standard section guard bars through splicing bolts. The construction method of the end beam is basically the same as that of the wave beam.

Q: Diesel hammer piling machine principle: The guide rod type diesel hammer is pressed on the pile cap with a plunger as a hammer seat, and the cylinder is used as a hammer head to move up and down along the two guide rods.When in operation, the pile hanging in place pile frame in Longmen, then put the diesel hammer at the top of the pile, the hook will lift down the cylinder, and the cylinder sleeve off hook to the whereabouts of the piston, the cylinder will be closed in the air compression cylinder rocker pin until the pressure continues to fall outside the cylinder pushing hammer on the base of the fuel pump, fuel pump will be injected into the cylinder oil mist, oil mist meet high temperature gas burning immediately above, blasting, explosive shock down pile., to push the cylinder to cylinder to rise, fall along the guide rod, and the beginning of the second impact cycle.

Q: Why do some people need to dig the foundation and pile it up to dig a hole?: First of all, depends on the type of your pile, prefabricated or bored pile.If it is a bored pile, then it is obvious to dig first.If it is a prefabricated pile, then pile it directly, then dig it.

Q: How to hit a pile of photovoltaic power generation?: Do you have anything to live with? I have a photovoltaic machine. What ground is it, earth or stone?

Q: Safety requirements for diesel hammer pile drivers for diesel hammer pile drivers: 11 water cooled diesel hammers shall be maintained with sufficient cooling water for continuous work and shall not be used without water. 12 operation, diesel hammer final ten hit penetration should comply with the provisions of the use manual, when every ten hit penetration is less than 20mm, should stop hammering or replace pile hammer. 13 during the piling process, lubrication and repair shall not be performed. 14 when the hammer (pile) of pile driver is used, the minimum distance of hammer (pile) from the top of column shall be ensured. 15 after the pile is inserted, the verticality of the pile should be corrected in time. When the pile is embedded in the 3M, the pile should not be taken for walking or turning to correct it. The 16 batter pile, the vertical pile should be vertical, the pile into fixed, and then began to tilt, tilt 18.5 degrees in the post, should not raise diesel hammer. Track three fulcrum type pile frame in the backward of batter pile, should use the rear leg cylinder; track type pile frame should be increased after the support platform, and clamping rail clamp. 17 when driving, the diesel hammer shall be lowered to the lowest position, and the slope shall be in accordance with the instruction manual. Self propelled pile drivers should be manned by hand. When walking on the ramp, the center of gravity should be moved to the top of the ramp. The distance from the pipe type piling machine to the end of the roller tube shall not be less than 1m. 18 during operation, the slewing brake should be slow, and the track type and walking type pile stand shall be turned in the same direction, not more than one week.

Q: What safety measures should be taken when assembling a pile driver?: 4, mechanical equipment installation and transportation safety mattersThe mechanical equipment should be installed in a safe place, not in the rock slope landslide, or may be installed by flood invasion and flying stone in place, to ensure personal safety and machinery.The room layout shall be constructed according to the mechanical instructions or actual needs. Room to ensure mechanical windproof and rainproof, antifreeze and other requirements, to the appropriate area, convenient operation and maintenance, and adequate lighting, good ventilation, shutdown protection facilities for temporary use of machinery should be necessary.Mechanical equipment shall be installed according to the instruction manual and relevant regulations. After installation, safety inspection and performance test shall be carried out, and may be put into use after the test operation has been qualified.When the mechanical equipment is transported, make sure the binding is firm, the center of gravity is reliable, the brake is reliable, and the traffic safety is ensured.When mechanical equipment is unloaded, be sure to handle with care, forbid to throw and throw off from the car, use dump truck to transport machinery, forbid dumping with dumping method.
