The working span, the coverage area, the thrust and pull and the controls of a jib crane are the basic characteristics that define a jib crane. This article will provide you with some important information to make the right decision for your needs. Read on to learn more. We also cover some common types of jib cranes and how to choose the right one for your needs. Here are a few examples of beam-mounted jib cranes.
The working span of a jib crane
One of the most important factors to consider when choosing a jib crane is the duty cycle. This includes the types of loads, frequency of use, and weight of each load. The right jib crane should meet these demands. Otherwise, the crane will wear out faster, require frequent maintenance, and decrease its service life. Classification also helps you choose the right crane for your specific needs.
A jib crane has two basic types of forces: thrust and pull. The latter is a pushing force while the former is a pulling force. These forces are equal but opposite in direction. The full capacity of a beam-mounted jib crane is defined as its maximum thrust and pull. A typical beam-mounted jib crane has three types of force: thrust and pull. Each of them exerts a different force, depending on the type of load.
The coverage area of a jib crane
Beam mounted jib cranes can be installed anywhere, including inside buildings and machinery. The cranes’ multiple installation options include ceiling, wall, and floor mounting. They are capable of supporting all kinds of manipulators, including overhead or under-the-door types. Because of their dual arms, these jib cranes have excellent coverage area and are ideal for a variety of applications.
Jib cranes are available in wall-mounted, mast-style, and freestanding styles. A wall-mounted crane is particularly useful for supplemental applications where overhead cranes can’t be installed. The wall-mounted version offers a large, circular coverage area and doesn’t require foundation support. Wall-mounted jib cranes can also be customized to accommodate different lifting needs and can be installed close to ceiling obstructions, providing maximum clearance.
Alternatively, you can opt for a foundationless jib crane. The foundationless type can be installed in concrete slabs without any special foundation. This allows for more flexibility. You can move it from one place to another without removing the entire crane. These cranes can span 10 to 40 feet and rotate 360 degrees. They don’t require a special foundation because the support is provided by an overhead structure.
Thrust and pull on a jib crane
The thrust and pull on a beam mounted jIB crane is a critical consideration in determining the right height for your lifting job. You can calculate this distance by calculating the span of your crane, the distance between the anchor bolts embedded in the concrete, and the distance between the brackets on either side of the crane runway. Then, determine the corresponding pull and thrust on the crane.
The rated capacity of a beam mounted jib crane refers to its maximum “live” weight. The rated capacity is the maximum weight of the crane, plus any hoist and trolley weight. If the weight exceeds 15% of its rated capacity, it is considered a “live” load. For most applications, this is sufficient. For larger cranes, a flat bed truck or trailer is required. A truck with a trailer can accommodate the large jib crane, but you must keep in mind that it is also necessary to palletize the crane to protect the finish.
Controls for a jib crane
Motorized jib cranes have a range of controls for guiding their motion. Motorized versions may be air-powered, pneumatic, or both. Some models come with a top-entry electrical collector assembly, eliminating the need for internal wiring in the pillar. Powered boom rotation is possible with a motorized jib crane. Depending on the application, the motor may be powered by a single or multiple-phase motor.
Automatic jib cranes are operated by preset cycles. The auxiliary hoist operates faster than the main hoist. Axial load is the force applied to the crane’s supporting structure when lifting a load. A jib crane’s axial load formula is equal to the weight of the load x the design factor. Similarly, a bay is the space between two building frames measured parallel to the crest.
