Know the Types Of Soil Sampling Winches

Author: Milian Dixon

Soil sampling winches are used for hoisting different activities in the field. They are either fixed to its leg or to the frame of a tripod. There are certain factors that play an imperative role in selecting a particular winch such as:

  • Type of tripod
  • Required tensile force
  • Utilization frequency
  • Desired hoisting speed and working depth
  • Nature of the work.

Soil sampling winches can be both a light hand winch and a heavy hand winch. The heavy hand winch is fixed to the frame of the heavy tripod with a double fixture whereas the light hand winch is attached to the light tripod with a single fixture.

Heavy hand-operated winch

It is provided with a free fall facility to drop the object fixed to its cable. This means that the cable drum can move independently when the bailer is lowered. The heavy winch can be operated by either one or two persons. It has the tensile force 18 kN. While operated by two people, a crank is joint to the cylinder shaft on either side of the winch. The speed reduction is used while operated by a single person for extremely heavy hoisting. It consists of several synthetic or steel cables for fixture on the hand winches.

Light hand-operated winch

The light hand winch is operated by one person and is joint to the light tripod with one fixture. Also, it has the tensile force of 4 kN.

For soil sampling winches, a tripod is vital for a bailer boring set that can also be used for drillings at greater depths, and heavier augering or soil core sample equipment applications.

In choosing a tripod, weight, working height, and maximum load capacity are some of the determinant factors. However, nature of the work performed plays a stronger role in deciding the tripod besides soil drilling performance. Each of its leg has three parts. On top, a snatch block is attached to both tripods, working as a guider for the cable. At the bottom, the heavy version's legs are provided with a point to resist sliding. To improve the bearing capacity, especially in soft soils, a separate base plate is given for each leg. The legs of the lighter one has base plates, whereas the heavy tripod has a frame to fix the heavy hand winch.

The three-piece aluminium tripods meet the specific requirements for its light and easy working. These parts can be coupled quickly, and have limited length so that the users can set them up very quickly. The supreme quality aluminium is very light in weight and requires almost no maintenance. The limited weight and length of the various parts of tripods make easier for others to transport it in a normal station wagon.
