Piling Rigs for Sale: What are They?

If your line of work is involved with the mine drilling exploration industry what will your reaction be like if you came across piling rigs for sale? Would you be compelled to check it out and find out what it is to your business? 

Before delving deeper into this, we need to have a clear picture of what a piling rig is. 

Defining Piling Rigs

Piling rigs are a qualified construction machine. They are basically used for piling purposes in foundation engineering and are usually used for drilling in silty, sandy soil, clay, etc. Besides those areas, their application has also found its way in diaphragm walls, cast-in-place piles, foundation reinforcement, and several other similar foundation projects. 

With its power of engine rated at around 108-450 kW, maximum pile diameter 1.5-4 m, output torque at 60-40 kNm and depth of 60-90 m — these are the attributes that allow it to meet construction and building requirements for foundation engineering projects. 

These types of drilling rigs are used in driving piles deep into the soil or ground to create foundation support for bridges, buildings, and other structures.  It makes use of automatic lift box-type mast, hydraulic crawler chassis, telescopic drill pipe, depth indicator, auto vertical adjuster, etc. The operation would be applying load sensor and hydraulic pilot control, to facilitate ease of control. 

The rig is primarily used in piling construction in wet soil (rotary bucket), dry soil (short screw) and rock (core drill). It is made possible when you equip it with a drilling tool, long screw drill, vibratory hammer, or diaphragm wall grab, and many others for it to have many different functionalities. 

A heavyweight will be positioned between guides. By this measure, you provide it a mechanism for an upward and downward movement in a single line. When they are placed upon a pile, they will be raised instead of guided by hydraulics. Reaching its optimum height, the weight will be released. Expectedly, such action will hammer the pile, and thus drive them down into the ground.

It is mainly applied in foundation engineering of expressways, industrial and civil buildings, water conservation projects, municipal constructions, diaphragm walls, and even for slope protection. 

Piling Rigs for Sale in Perspective

Buoyed by many different kinds of road infrastructure developments and metro rails,  the piling and foundation equipment industry is gradually being renewed with distributors and manufacturers offering robustly built machines to undertake piling works at deeper depths. They are marked by flexibility and greater precision in working at hard strata and different kinds of soil formations. 

It is obvious to see also that the industry is slowly veering away from the use of tractor mounted rigs. The same thing is also true with tripod methods that cater to complex structures,  with hydraulic rotary piling rigs as one of the modern technologies that it is using. This wave of change is revolutionizing execution speed, boring precision, and allows for the better handling of greater depth and larger bore diameters.
