Different Types Of Solids Handling Equipment

Different Types of Solids Handling Equipment

One of the most important aspects of loading and unloading operations is the proper handling of solids. The physical properties of these objects, coupled with the associated stresses and moments, are subject to significant changes upon contact with varying conditions. For example, in a dry dock, when the shipping material is subjected to high-impact landing, aqueous film formation may form, causing cracks to widen and oozing to occur. Likewise, when heavy machinery is placed in the center of a large barge, there is a good chance that the barge will tip over. 

To prevent such accidents from occurring, it is important for material handling specialists to be well-trained and familiar with various types of loading and unloading equipment. Here are some of the more common types of material handling equipment used in the loading docks and yards:

The chute is a specialized piece of equipment that is used to increase the effectiveness of the loading and unloading systems at a dock or heavy plant. A chute system includes a chute, which carry a single weight, and a series of individual chutes connected to a central point. Most chutes are manually operated, but special systems, such as variable speed motors (VMS), are also available. Some modern chute units employ electronically operated sliding doors to facilitate heavier loads.

Another important type of equipment is the belt-conveyor system. This piece of equipment is used to transport bulk materials such as concrete, gravel, steel, and other manufactured products. Belt conveyors consist of a large flexible belt, attached to a motor that can be remotely controlled. Most belt conveyors are powered by electric motors, but some systems are powered by mechanical power such as steam or hydraulic. Certain types of automatic belt conveyors feature safety features such as automatic pressure control and cooling systems.

The scissor lift is another important type of bulk material handling equipment. It consists of a straight shaft, supported by four corner rollers that are secured to the ceiling or other framing members. There is a platform at the end of the scissor, from which a worker uses a lifting device to raise or lower various types of chutes, buckets, or drums. Common types of scissor lifts include boom, straight, and scissor lift, but specialty models are available that include freeze-resistant components and other features. Scissor lifts are frequently used in mining, construction, and manufacturing operations where heavy loads are required.

Bucket elevators are another popular piece of material-handling equipment. Bucket elevators are designed to lift and position materials of different types, such as raw materials and finished goods, on a raised surface. Bucket elevators usually contain a metal case or an interior feeder to hold the material. A bucket elevator is useful for transferring materials from one level to another, and it is especially useful for safely storing materials above ground level.

Belt conveyors are mechanical devices that move materials (usually in a straight line) along a continuous and pre-determined path. The most common use of belt conveyors is to transport products or raw materials from one floor to another, usually through the use of pulleys or counter-weighted rollers. However, belt conveyors can also be operated manually, or with the use of automated control.

In addition to the operation of the conveyor itself, the machine also contains various features to assist in loading, unloading, and positioning of items. The size of the area in which the conveyor will be placed, the number of moving parts, speed of rotation and the material characteristics of the product to be carried will all affect the type of belt conveyor to be used.
