What is lift slab construction used for?
This method of construction allows for a large portion of the work to be completed at ground level, negating the need to form floor work in place. The ability to create monolithic concrete slab s makes the lift slab construction technique useful in quickly creating structures with repetitive form work, like parking ramps.

What is a construction lift?
As mentioned, construction lifts have two different power sources: electric (battery powered) and gas (diesel-gas powered), sometimes referred to as internal combustion (IC). There are also hybrid construction lifts, which use a combination of gas and electric power sources, although these are less common.
What is a boom lift?
However, unlike the articulating boom lift, the telescopic boom arm does not bend – it extends diagonally, allowing a worker to reach very high elevations . In fact, out of all the construction lifts, telescopic boom lifts can reach the highest heights. Telescopic boom lifts’ arm has a mounted platform that can hold one worker.
What is a slab scissor lift?
The other type of scissor lift is the slab scissor lift. Like rough terrain scissor lifts, these forklifts move vertically (up and down) and not side to side. Unlike rough terrain lifts, slab scissor lifts are typically electric rather than gas-powered, and work better for indoor areas or areas with flat surfaces (like concrete). They also tend to support slightly less weight (up to 2,000 lbs), even though they have the same wide platform as rough terrain lifts.
How tall is a rough terrain scissor lift?
Like vertical mast lifts, rough terrain scissor lifts move only vertically (up and down) and reach up to around 60 feet. Note that this maximum height is less than that of boom lifts, however, they have wider work platforms and have a larger weight capacity (2,500 lbs).
What is a knuckle lift?
Articulating boom lifts , also known as knuckle lifts, are types of boom lifts with a flexible, bendable arm with a mounted work platform that reaches elevated heights. They have a turntable at the base of the machine that allows workers to adjust the arm to bend in various directions, maneuver around obstacles, and access hard to reach areas.
What is a gas powered lift?
Gas powered construction lifts, also known as internal combustion (IC) lifts, are the most common type of construction lift when it comes to power sources. They typically run by using an engine powered by diesel fuel, but sometimes can run with propane.
What is vertical mast lift?
Vertical mast lifts are aerial construction lifts designed to help construction workers reach elevated heights in tight, small, or narrow spaces. They are similar to scissor lifts in the sense that they move vertically (up and down only), but they tend to allow for even tighter spaces than articulating boom lifts or scissor lifts. Additionally, vertical mast lift platforms often allow 2 or more workers, and they are very easily transported and stored. However, keep in mind that their maximum height is often lower than scissor lifts and boom lifts.
What is a construction lift?
The Main Types of Construction Lifts. Industrial Forklifts. An industrial forklift is often used to lift items up vertically and this piece of equipment is perfect for moving materials from one location to another. While these forklifts are normally seen in warehouses, it is likely that you will use them inside a building for finishing touches.

Material lifting wire rope
A steel cord that has several cables in its core that are twisted together. This part is made in different sizes. This part transmits the rotational force generated by the electromotor to the lift bucket.
Construction lift bucket
As mentioned, the lift bucket is used to transport materials such as cement and concrete. They are manufactured in different capacities depending on the force ported by the lift.
The lift stand
This part places the lift on the surface, and the rails attach to those components of the chassis. An ideal lift has strong, secure stands, and the electromotor used has armature winding with full copper and high quality and low ampere and also has the high quality gearbox.
Essential tips on using construction lift
The lift is designed to move materials, but some people mistakenly use it as an elevator, which can cause danger and harm for the person.
How to set up construction lifts
After mounting the lift and its components in place, you should position the pedestal at a suitable distance and then mount the rail on the pedestals. Then insert the screws and tighten them. To assure the base strength you can put some bag on them in order to prevent probable tremor.
Essential and basic tips for buying the construction lift
Before choosing the right lift, you must first select the suitable lift to help you move materials with sufficient strength and security. To choose a construction lift, you need to take into account the various points that we will mention on a case-by-case basis.
Articulating Boom Lifts
The articulating boom lift is generally considered the most versatile type of aerial lift, as it provides access to elevated areas from different directions. The primary advantage of these lifts is the ability to reach over and maneuver around obstacles, making them ideal for jobs in tight spaces.
Telescopic Boom Lifts
While telescoping boom lifts are limited in maneuverability, they make up for it by reaching greater heights than most articulating lifts. The shaft acts as a telescope, stretching in a straight line each time a section expands. Because telescoping lifts extend to great lengths, their bases utilize a larger footprint for added stability.
Bucket Trucks
A bucket truck, also called a cherry picker, provides many of the functions of a boom lift. The only difference is that the boom is attached to a truck rather than a base, making it easily transportable and more efficient in maintenance work.
Scissor Lifts
A scissor lift works like its name suggests, with a series of metals slabs or tubes operating in a scissor fashion to expand or contract to the desired height. Both light and heavy-duty designs are available to enable operation on different types of terrain.
Forklifts
While forklifts are limited in their movement and reach capacities, they are much more efficient for jobs requiring quick and repeated maneuvering. With short, vertical movement as their main function, forklifts are prevalent in many warehouse and storage operations, and they excel at moving materials around a job site.
What is a boom lift?
Boom lifts are a distant cousin to the manlift. Both enable operators to perform tasks in aerial workspaces. However, boom lifts have several different features than traditional manlifts. Boom lifts can attach to work trucks and other vehicles to lift materials overhead.

What is an atrium manlift?
Atrium (Belt) Manlifts. Atrium manlifts, also known as compact crawler lifts, are the largest in the group. The heavy-duty lift is best for outdoor construction sites. The retractable legs and tank-like drive tracks, enable the atrium to securely sit on unstable surfaces like dirt, sand and mud.
Where is the jib on a manlift?
Operators can move up and down, left and right with ease. The jib feature can also be found on the atrium lift and boom lift. In the next section, we’ll look at the parts that make up a manlift and how it operates.
How to stay safe when operating a manlift?
Take note of the environment and potential obstacles, like tight spaces or unstable terrain, to stay safe when operating a manlift. Smaller manlifts can raise an operator between tight spaces and crevices. If a worksite surface is unstable, outriggers posts and drive tracks can provide extra foundational support.
Who invented the lift slab method?
This method of construction simultaneously began development in 1948 by both Philip N. Youtz of New York and Thomas B Slick of Texas. Although the first patent for lift slab construction was given to Slick in 1955, the method of construction is commonly referred to as the "Youtz-Slick Method". His patent called for a method that would allow for fabrication to be completed at the ground level, eliminate a large portion of the formwork, create uniform floors of concrete, and reduce the labor to be completed at an elevated level.
