What is an Hoist Device?

While placer mining equipment is used to process mined materials that are collected mostly above ground, a hoist device is used to mine materials from deep underground. Underground mining equipments require a great deal more modifications than above ground equipments due to the limited work space and intricate underground tunneling procedures. Coal mining equipments often include the use of a hoist which move material from underground excavation sites, along a shaft, and above ground for processing.

Hoist Machinery

Hoist machinery can be applied to many types of Canadian mining equipment, as well as mining equipment around the world. Hoist technology is a fundamental component industry wide, and not limited to mining equipment. Manufacturing of mining equipment often employs the use of a hoist (in any of its various forms) so that materials can be moved efficiently and with ease.
Uses of Hoist

A hoist can be employed in several fashions. A drum hoist is mining equipment in which a single or double drum unit are engaged in the hoist maneuvering process with attached cables and a conveyor type mechanism for moving materials. A single drum hoist is used in smaller operations, while a double drum hoist is used to balance conveyors and hoist ropes. This type of hoist is minimally powered by external sources, and therefore requires minimal maintenance and offers low operating costs. They are also adaptable to a variety of environmental factors inside the mine shaft, such as flooding or other similar circumstances.
Hoist Mining Mechanisms

Friction hoist mechanisms are similar to their drum hoist counterparts, but are different in their use of tail ropes and counterweight technology. Refurbishment of mining equipment can include the modification of these types of hoist machinery. Mining operations are limited in deeper shafts with friction hoists,  but the additional ropes and counterweights allow for nearly nonstop processing.

Coal mining equipments are easily adaptable for any type of excavation operation. A good maintenance staff is one which employs professionals who are familiar with a variety of hoist machinery components. Hoist machinery components can also include revolving movements rather than conveyor movements to expand the use of the technology for a variety of mining tasks.
Mining Hoist Technology

Manufacturers can apply the hoist technology refurbishments, maintenance tasks, and modification support to almost any mining operation. Coal mining equipment manufacturers need people who work on their machines to have knowledge of the industry wide equipment components so that they are able to predict problems and produce solutions for any of the modification needs that are presented in typical and atypical procedures. Hoist components are no exception, even though they are fundamental in nature compared to more complicated machines.

Mining equipment in Canada and abroad requires practical knowledge that can be applied by a skilled hand to keep in pristine running condition. Mining tasks are dangerous, heavy, and subjected to extreme environmental conditions.
