What Is a Lifter?
A lifter is a machine or device used to lift or lower heavy objects.
Industrial equipment that raises pallets loaded with products or products in boxes is often referred to as a lifter. It uses mechanical force to lift objects. It uses a motor or hydraulic system to generate force and has a mechanism to transmit it.
Thus, they can lift heavy objects that cannot be transported by human power. In addition, safety devices and control mechanisms are incorporated to ensure that objects are lifted securely and safely. Designed to minimize the risk of accidents and injuries, the lifter also contributes to improved safety.
The main benefits of using lifters are increased work efficiency, labor savings, and reduced risk of back pain, since lifting and lowering heavy objects is facilitated by the use of lifters.
Uses of Lifters
Lifters are used in a variety of industries and sectors. The main areas are the logistics industry, the construction industry, and the manufacturing industry.
1. Logistics Industry
In the logistics industry, lifters are widely used for transporting and storing goods in warehouses. Lifters such as pallet lifters and forklifts can lift and move heavy objects efficiently. They are also utilized for shelf placement and loading/unloading operations.
2. Building Industry
They also play an important role on construction sites and in the heavy equipment industry. Crane lifters, for example, are used to lift large construction materials and machinery. These lifters are utilized to facilitate the placement and transportation of supplies at construction sites.
3. Manufacturing Industry
In the manufacturing industry, lifters are used in processes, such as assembling and packaging products. In the automotive industry, lifters are used to lift car bodies and handle parts. They may also be used to move and position items on the production line.
Principle of Lifters
Lifters are designed to lift heavy objects using mechanical force or energy. It consists of a power source, a lifting jig, and a control mechanism.
First, energy is supplied by a power source. Common power sources include motors, internal combustion engines, and hydraulic systems. The energy supplied by the power source is converted into carrying power through appropriate mechanisms.
Lifters also incorporate components that are appropriate for the object to be lifted. Forklifts use forks, while crane lifters are equipped with hooks and lifting devices. These can be replaced depending on the application.
Control mechanisms may also be incorporated. The control mechanism controls the operation and movement of the lifter to ensure safety and accuracy.
Types of Lifter
There are several types of lifters: hand lifters, electric lifters, hydraulic lifters, and table lifters.
1. Hand Lifter
These lifters are capable of lifting heavy objects with little force by means of a handwheel or pulley. The functions of lifting and moving are often required simultaneously for product loading, and most products are provided with casters for moving.
Since hand lifters require no power source other than human power, there are no restrictions on where they can be used. They are also characterized by relatively low price and running costs, as they do not require electricity or fuel costs.
2. Electric Lifter
These lifters have a structure in which the handle portion of the hand lifter is replaced by a motor. Some products are equipped with a battery as a power source, and can be used as a mobile cart by charging the battery in advance. Because they are motorized, they contribute to work efficiency and manpower saving.
3. Hydraulic Lifter
This is a lifter that lifts objects by hydraulic force. There are types that control hydraulic pressure electrically and types that use a foot pedal to apply pressure.
They are often used to lift and lower heavy objects. However, they are not suitable for applications requiring large strokes or lifting speeds.
4. Table Lifter
This lifter can raise and lower the table to change the height to suit the work. They may be used to elevate boxed products.
The table lifter does not need to be moved and the power source can be wired or piped connection. They may be used as pneumatic lifters by connecting the air piping in the factory to an air cylinder.
