A winch is used to tension a rope, which then moves, lowers, or stabilizes an object. It is also used on smaller vehicles as a self-rescue tool, such as for pickup trucks and all-terrain vehicles (ATVs).

Many fire departments are installing winches on apparatus, typically using a square-tube receiver-style hitch and sometimes in multiple locations around the rig. This powerful and useful rigging tool has many uses, limitations, and potential dangers included in the advantages it brings to the scene. We will discuss these issues as well as rope inspection and other concerns.

When determining how you will use your winch, there are several important considerations you must keep in mind. First, winches don’t lift, they pull. Yes, you can elevate a pulley (snatch block), but you are risking fouling the winch line—they just aren’t made to lift or suspend an object. A winch is designed for pulling an object on a relatively horizontal plane. A rule of thumb is that anything pulled above or below 45° from horizontal is considered hoisting. Hoists use a different braking device than a winch. Most winches are made with dynamic brakes, meaning a gear system will automatically hold the load. Dynamic brakes use the winch gears for resistance, which is why they are unstable for lifting or suspending objects. If you were to use a winch to suspend a load, the load could easily slip, and the gears could become damaged, resulting in catastrophic failure.

So, a winch is not a hoist and should never be used as such. Hoisting requires an elevated anchor point; other options such as a recovery rotator, tripod, ladder truck, or crane are likely better options. Some confined space rescue crews carry hoists on their tripods. When moving people with a mechanical hoist or winch, carefully weigh your risk/benefit considerations. It is difficult to feel the load (human) bind up, which could result in an additional injury.

When selecting a winch, determine the largest load you would reasonably pull or stabilize. The average car weighs about 3,500 pounds. The working load limit (WLL)of a winch is a bit of a moving target. It is determined by the rating of the wire rope or synthetic rope. And, all winch ratings are determined by the tension developed by the first layer of rope on the drum. The first layer is the only layer that will provide a pull equal to the working load limit. The capacity of a winch decreases as more layers are wrapped on top of each other around the drum, changing the diameter of the drum. Each additional layer drops the WLL by approximately 10%. The capacity listed on the winch assumes pulling on the first layer of rope. This is similar to a high-pressure air bag’s capacity where the taller the bag grows, the less it can lift.

Before using the winch, check the vehicle, fluids, tires, brakes, etc. Check that the winch is powered up, that the line plays out smoothly and is in good working order, that there are no broken or loose parts, and that electrical connections are bright and tight.

As stated, WLL is determined by the rating of the wire rope or synthetic rope on the drum. It is important to consider other factors that will reduce a winch’s capability. Wire rope can be damaged by pinching, fraying, kinking, or corrosion. Hazards at the scene can cause damage. The same is true for synthetic rope. It is prudent to limit your pulls to a value significantly less than the winch’s WLL. Industry experts suggest that it is good to maintain a 4:1 safety factor for every pull. Using this factor, a 9,000-pound winch should be limited to a 2,250-pound pull. This is a big dip in capability; however, keep in mind that if you are stabilizing a vehicle, most of the car’s weight is transmitted straight to the ground, and unless the vehicle gets in a bind, you are not pulling the entire weight. If you are just holding the vehicle in place, the demand on the winch is much less. If you are pulling the car up a hill or out of a body of water (the car is now full of water for a bit), these added loads will need to be considered in the planning.

National Fire Protection Association (NFPA) , Standard on Automotive Fire Apparatus, suggests a minimum of 75 feet of rope for each winch. You can load more rope, but in winch work, more rope is not necessarily better. Keep in mind that to achieve the maximum pull from your winch, you need to lay off enough rope to get to the first layer (the layer closest to the drum). You do not want to stretch out all the rope and load the rope termination at the end of its line coming out of the drum either—this is a sure way to break your winch. Always maintain four to five wraps of wire rope on your drum. The drum is meant to be loaded, not the very end of the rope. A drum with too much rope will mean that you may not be able to pay enough off before reaching your pull point and you will be winching on the upper layers of the drum. This will reduce your pulling power and reduce the efficiency of your winch motor. Apparatus placement is critical in winching operations to obtain maximum pull. Ideally, the apparatus is straight in line with the load, and the distance between the apparatus and the load leaves four to five wraps of wire rope on the drum.

The popularity of commercial drones has been steadily increasing over the past few years. From high-resolution cameras to logistics and transportation, drone technology has evolved to the point where it is no longer a fragile camera that cannot raise payload items.

Heavy lift drones are large drones with the ability to carry and operate 10 pounds and more of heavy payloads used to transport cargo, packages, food, medical supplies, etc. These drones are not only designed to lift cargo and materials but also heavy-duty cameras used for photography and videography.

If you are looking for such a heavy-duty drone that can carry weight or things, you are just on the right page. Below, we review the best heavy lifting drones in the market. We'll also look at how a heavy payload drone works and how much weight a drone can carry.

How much weight can a drone carry?

Asking how much weight a drone can carry is like asking how fast a car can go. The short answer is that how much a drone can carry depends on the type of UAV and the purposes for which it is designed.

The function of amateur drones is not to carry extra loads, but to take pictures and help beginners learn the basics of flying. They can usually only hold 500g, or even less than 100g in some cases.

Heavy lifting drones are different in that they are specifically designed to carry weight, such as those used for drone delivery. The technology behind these is quite impressive, and they can generally handle payloads of 20 kg to 220 kg. Some drones have the ability to carry more than 50% of their original weight as an additional payload.

What are heavy lift drones used for?

Many companies have identified commercial and military applications for heavy payload drones and are taking advantage of the opportunity to use drones for multiple purposes to effectively manage their workflows.

Engineering projects

Engineering companies can make good use of heavy-duty drones carrying high-quality cameras, which they can use for in-depth projects such as maintenance inspections, transmission cables, and oil pipelines. A drone in construction can also help engineers perform various critical activities such as airport planning and road maintenance, making efficiency exponentially higher.

Cargo and delivery

Drone delivery is one of the fastest-growing and most popular applications of drones. Cargo drones are being used to deliver medical and healthcare supplies such as medicines, blood, and vaccines. Heavy lift delivery drones can also deliver goods and mail to remote communities, which is both faster and cheaper than transitional transportation methods.

Agriculture sector

Farmers can reap multiple benefits from heavy-lift agricultural drones, which they can use for spraying fertilizer or pesticide. Using this technology to perform these time-consuming tasks can help farmers save significant amounts of overhead and time.

Disaster relief

Heavy lift drones are also used for emergency response, which can bring food, fuel, water, supplies, medicine, communications, and even electricity to areas hard hit by natural or man-made disasters - and can do so faster and more efficiently than any other platform.

Military service

Military heavy lift drones have improved military capabilities around the world in many ways; they are used for intelligence, surveillance, reconnaissance, and transporting materials such as explosives and heavy weapons. They can also deliver equipment to areas that are too dangerous for manned flight, such as resupply in frontline areas, and casualty evacuation.

Components of a heavy payload drone

The average heavy payload drone is made up of three important parts. Below is a list of the parts that make up a heavy lift drone and what they do:

Heavy lift drone motors

Taking off with heavy weight is not an easy task. The heavy lift drone motors must generate a lot of upward propulsion. Generally, larger and heavier drones use brushless motors because they can carry the extra weight of the electronics. In addition to this, innovative counter-rotating drone motors are becoming popular, offering greater thrust and higher efficiency than standard single-rotating motors.

Heavy lift drone propellers

Constructed of carbon fiber, which is lighter than plastic, the propellers of heavy-duty drones provide better flight performance. Typically, heavy lift multi-rotors have greater than four propellers, their longer blades give the stability and balance needed, and the smaller pitch easily carries the extra weight associated with the longer blades.

Heavy lift drone gimbal

Gimbals for heavy-duty UAVs are designed to accommodate a wide range of cameras, sensors, and payloads, providing stable footage for numerous industrial applications, such as mapping and surveys. With the gimbal attachment, the concern that the pilot must keep the drone stable while flying is eliminated because the gimbal's sophisticated technology allows for an almost completely automated process. There is no need to worry about the drone's lens wobbling.

Factors to consider before buying a heavy lift drone

Before purchasing a heavy lift drone, it is important to consider the features and functions that the drone has to ensure that it will do its job.

Purpose

The first thing you need to consider before buying a drone is "why should I buy it?" because this will determine how you use the drone and whether it needs to carry additional cameras or sensors.

Flight time

Since you will be using these types of drones to lift objects, you must consider the battery life that will allow you to stay in the air for longer. If a drone can carry 20 kg but can only stay in the air for 5 minutes, it is useless because it can't even reach the set destination.

Type of payload

We recommend buying a drone with a built-in camera, but not every drone is equipped with one. You need to be aware of the mechanism you will use to allow the drone to carry a payload. Can it be carried with a traditional connection, or will you need to customize a solution for your specific situation?

Price

Another key factor is whether the price of the drone fits your budget. Drones range from entry-level to high-end drones, with all the bells and whistles. Before spending any money, you need to think about the drone model and features you really need.

Can you buy a drone that can lift a person?

Yes, certain large commercial drones can lift and carry a person, like Ehang 184 and GRIFF Aviation 300. Their lifting capacity depends on the power, dead weight, type of propeller, and the number of motors.

In the past, the batteries were too heavy to carry enough energy to create enough lift to get off the ground. The motors were not efficient enough to convert enough power to the blades. However, with the development of brushless motors, LiPO batteries, and gas powered drones these conditions have changed.

Nowadays, many giant drones can lift more than 400 lbs, which means they can easily lift a person as well.

What is the largest drone you can fly without a license?

According to the FAA Small Drone Rule Part 107, for drones weighing more than 250 grams, you need a license or permit, even if your drone is just for fun.

How far can a large drone fly?

It depends on what the large drone is designed for. Delivery and passenger drones generally have a range from 500- km. But efficient surveillance drones needs need a range of 10-150 km, and for mapping drones a range of 4-8 km is sufficient.
