Scissor Lifts : The scissor lift contains two superimposed platforms and is suitable for small spaces. Retractable levers that extend in a zigzag manner are placed between these platforms. Portable scissor lifts that are movable and fixed scissor lifts that are attached to the base are available. The hydraulic mechanism at the base will offer a smooth and steady operation. In-Ground Auto Lifts : In-ground auto lifts are designed to maximize the space.
A hydraulic lifting mechanism placed underground is used here and it can be operated with a switch connected to the elevator. Most of the large automotive repair shops use in-ground lifts that are hidden under a shop floor when not used.
Durability, flexibility, and safety are the advantages of this lift and the limitations include complex installation. Single post lifts, side-by-side twin post lifts, and heavy-duty fore-and-aft lifts are different categories of in-ground auto lift.
Alignment Lifts : Alignment lifts are specially designed for handling wheel alignment works and its appearance looks similar to that of a four-post lift. There are alignment lifts with a different lifting capacity that is suitable for small cars to large automobiles.

November 1. October 3. September 4. Rotating lift tables are used where access to all sides of the load is required. They are designed with a rotating platform and can have reduced heights, which allows for greater access. Lower profile lift tables are designed to reach heights as low as 3 inches making the platform accessible by a pallet jack. Though they have thinner lifting arms, they still have a capacity of over lbs. Stainless steel lift tables are mainly used in the food and pharmaceutical industries, where there are high standards for hygiene and sanitary conditions.
The corrosion and rust resistance of stainless steel makes them easy to clean with solvents and water. High capacity lift tables can have a capacity of 8, to 10, lbs. As seen in the image below, they have extra thick scissor arms, large low pressure cylinders, and additional supports. Ground entry lift tables have ground level access to the platform due to concerns regarding tripping or being in confined spaces. Access to the platform is by a cut away section in the shape of a "U" or "E", which makes them able to be loaded with an open bottom pallet or skid.
Tilting lift tables are for handling containers with loose parts. The platform lifts to an ergonomic height and tilted toward the operator, which reduces the need for bending and stretching.
They are available with tilt angles of up to 90 degrees. Tandem lift tables combine standard lifting with additional lifts of length or width providing the extra benefit of increased platform size to accommodate larger loads with extra edge and side load capacity. Multi-stage lift tables stack one pair of scissor arms on top of another with one lift table on top of another, which increases vertical travel but maintains small platform size.
Hydraulic lifts are constructed from steel and have precision accuracy. Their sturdy and durable design has made them popular in a wide variety of industries. Listed below are a few of the industries that rely on hydraulic lifts for their efficiency and ability to supply a great amount of force.
Electro-hydraulics is a common use of hydraulics in industrial applications. The main advantages of hydraulics are its rapid response times and precision.
Plastic processing, metal extraction applications, automated production, machine tool industry, paper industries, loaders, crushers, presses, and the textile industry are some of the industrial uses of hydraulics. The image below is a hydraulic press from the plastics industry. Mobile hydraulics have the advantage of being able to be moved to different conditions and situations.
They are especially useful in the construction and building industries where hydraulics are used as cranes, excavators, backhoes, and earth moving equipment. Pictured below is a concrete boom truck using a hydraulic arm to unload concrete.
The automotive industry is the largest user of hydraulics. Production, repair, and internal components on cars all use hydraulics. The image below shows the use of hydraulic automation in the production of trucks. Marine hydraulics deliver linear and rotary force and torque rapidly and efficiently. The three types of marine hydraulic systems are open, closed, and semi-closed. They are used for cranes, mooring and anchor winches, stabilizers, steering, thrusters, propellers, and platforms.
Components for aircraft have to meet strict standards before being approved for use. Hydraulic pumps and valves meet aircraft regulations and are an essential part of aircraft design and production. The image below provides a list of some of the ways hydraulics are used on an aircraft.
Hydraulics are ideal for mining for the same reasons that they are used for other manufacturing operations. Power, controllability, reliability, and serviceability are necessities in mining because of the dangers that are involved.
Unlike other manufacturing, mining works on a huge scale requiring massive equipment. The power and force provided by hydraulics fits the conditions.
Hydraulics lifts are heavy duty equipment that can supply a great deal of force. The first of those requirements is that operators must be an adult, over 18, that has been fully trained in the operation and dangers of the equipment.
OSHA regulations regarding lifts are generalized to include any form of work that has to be performed on a platform off the ground. Standard The general outline is for scaffolds but has been expanded to apply to lifts. It further covers guardrails and railings. Aerial lifts are defined as mobile elevating work platforms MEWPs. ANSI A92 requires aerial lifts to be equipped with two types of sensors: one that sounds an alarm and prevents the machine from operating when the load exceeds safety limits, and another that triggers an alarm when the slope level gets too steep and prevents movement of the chassis or work platform.
Gates cannot be chains and must have toe guards. If used for outdoor work, wind speed sensors are required. Platform railings must be at Minimal concrete depth required for a two post above ground lift is four inches. Thicker concrete is required for two post lifts exceeding a 12, LB. This is the most common style of two post above ground lift found in the USA.
The two post above ground lift was developed for automotive facilities that were unable to install in-ground lifts. Many automotive service centers are built over rock and excavation is impossible or impractical or buildings located on property with a high ground water table. The pressure of the hydraulic fluid is regulated by the factory preset pump valve. Important: The weight of the vehicle to be lifted must be evenly distributed on the four arm pads. A 10, two post above ground lift will easily lift 10, LB.
That means 2, LB.
