Of the many hydraulic tools, one of the most versatile is
the hydraulic lift table. From small work benches to large platforms, these
efficient and valuable tools have proven to be a means for saving time and
labor. With the ability to hold any type of merchandise, tool, or equipment,
table lifts provide a safe and convenient way to effortlessly complete a task.
Hydraulic flat surface lifts allow workers to set the height
at which they wish to work as well as offer an ergonomically efficient method
to inspect and handle various types of items. Lift tables are designed to lift
heavy loads for the protection and safety of workers.
What is a Table Lift?
Hydraulic lift tables have a very simple and compact design
that consists of a flat platform, base, some form of legs, hydraulic cylinders,
and a motor. All of the components are made of steel or stainless steel to
ensure the tables ability to withstand rugged use.
The platform is where the item to be lifted is placed. The
platform comes in several forms, which include flat welded steel, conveyor
rollers, or perforated surfaces. The thickness and type of the platform depend
on how the table will be used with some applications being more stressful requiring
a sturdier and durable surface.
There are several varieties of table bases that vary
according to the needs of the application. Some tables have wheels and can
function like a forklift. This type of table provides greater mobility and
flexibility. Tables that are used for welding, metal work, and heavy-duty use
have a four-sided rigid steel base for extra stability.
A common part of a table lift is scissor legs that are moved
up and down by the hydraulic pump system. The number of legs varies between two
up to as many as eight. The heavier the work piece the more legs the table
The key to a table lift is its motor and hydraulic
cylinders. Much like the other aspects of the table, the number of hydraulic
cylinders varies. For heavy duty work, the hydraulic pump system may have as
many eight to ten cylinders. The number is limited by the size of the platform.
The lifting mechanism for a hydraulic table lift includes a
motor to power the hydraulic cylinders. It can be located under the table by
the cylinders, attached to the side, or be a remote power pack. The power of
the motor is dependent on the number of cylinders and the use of the table.
Table Lift Operation –
When the motor of the hydraulic lift table is activated, oil
is pushed into the ram of the hydraulic cylinders. The force of the ram
compresses the oil, which pushes the table upward. When the appropriate height
is reached, the ram remains in position holding the platform in place.
The determination of how rapidly the table raises the load
is decided by the weight of the load. Each type of table lift is designed to
conform to a specific capacity, which can be a few hundred pounds up to several
hundred. Tables with lighter load capacity raise quickly.
To lower the table, the motor releases the oil, and the ram
retracts slowly lowering the load and the table.
