Lifting equipment

Lifting equipment is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lifting equipment rather than just read about it. In short: Lifting equipment, also known as lifting gear, is a general term for any equipment that can be used to lift and lower loads. Types of lifting equipment include heavy machinery such as the patient lift, overhead cranes, forklifts, jacks, building cradles, and passenger lifts, and can also include smaller accessories such as chains, hooks, and rope.

Key takeaways

Lifting equipment belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lifting equipment to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lifting equipment from memory before moving on to harder problems.

Reference excerpt

Lifting equipment, also known as lifting gear, is a general term for any equipment that can be used to lift and lower loads. Types of lifting equipment include heavy machinery such as the patient lift, overhead cranes, forklifts, jacks, building cradles, and passenger lifts, and can also include smaller accessories such as chains, hooks, and rope. Generally, this equipment is used to move material that cannot be moved with manual labor, and are tools used in most work environments, such as warehouses, and is a requirement for most construction projects, such as bridges and buildings. This equipment can also be used to equip a larger number of packages and goods, requiring less persons to move material. Lifting equipment includes any form of equipment that is used for vertical lifting, and equipment used to move material horizontally is not considered lifting equipment, nor is equipment designed to support. As lifting equipment can be dangerous to use, it is a common subject of safety regulations in most countries, and heavy machinery usually requires certified workers to limit workplace injury.

Safety issues Failure or misuse of heavy machinery can lead to severe or fatal injury, leading regulations to be one of the largest debates in labor laws across the world. Each country sets its own regulations, and enforces different aspects of workplace safety when using lifting equipment.

In the United States The Occupational Safety and Health Administration sets regulations for all equipment. Contractors are forced to uphold usually strict rules to ensure safety of workers. All machinery is required to be developed by a certified engineer, contractors must follow manufacturer procedures, all users be professionally trained before operating equipment, and equipment must be inspected regularly.

In the United Kingdom The Health and Safety Executive sets regulations on equipment in the United Kingdom, under the Lifting Operations and Lifting Equipment Regulations. These regulations require equipment be registered on a Statutory Inspection Report Form, is adequate for the task, be subject to routine inspection, and the use of the equipment be properly planned out.

Working load limit

Lifting equipment can be assigned a working load limit (WLL) in the interests of avoiding failure. It is sometimes known as safe working load (SWL), but this alternative term is sometimes avoided due to giving the connotation of safety, which may not be guaranteed. The working load limit is calculated by dividing the "minimum breaking load" of the equipment by a safety factor. Working load limit as a concept is not restricted to lifting, being also relevant for mooring ropes. Minimum breaking load is also known under the terms of "minimum breaking strength" or "minimum breaking force". Working load limit of ropes are usually much smaller than their minimum breaking load.

Worked examples

Example 1 — a first encounter with Lifting equipment

Start with the simplest possible case. Write down what Lifting equipment claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lifting equipment before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lifting equipment ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lifting equipment

In research: Lifting equipment appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lifting equipment in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lifting equipment is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lifting equipment, Machines, so understanding it makes those chapters shorter.
In everyday life: Look for Lifting equipment outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Lifting equipment in simple terms?

Why does Lifting equipment matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lifting equipment?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
