Drill Tower

Description

Drill tower is a metal framework with certain height and span. It is the significant part of the drill rig. It is made up of crown block, the body, bi-layer platform, derrick and chassis, etc. It is used to locate and hang the drill rig's hoisting system. It is strong enough to store the drill rod or the drill collar. A good drill tower should enjoy large loading capacity, high strength, and toughness as well as integrate stability. What's more, there should be plenty of room for operating. Generally speaking, the available height of drill tower is from 8m-55m. The range of its hoisting capacity is from 5 to 1000 tons.

Classification

There are various standards to classify the drill tower. According to its structure, it can be divided into A, K drill tower and the mast drill tower. Based on its purpose, there are drill towers for oil wells, hydrological well, geotechnical engineering and engineering exploration. With concern to its working angle, the drill towers can be split into those of vertical angle and inclined angle.
