Aerial work platforms

An aerial work platform is a lift table that is equipped for working at a height. This means that it is equipped with appropriate safety equipment for people on the platform, control panels in the workman basket and often also traction drives to make it easier to reach another work location.


Word origin: from Latin agilis = easy to lead, flexible

Other general synonyms are dexterity and nimbleness.
In the technical field, agility primarily describes the mobility of a machine. If this word is chosen, one does not only want to emphasise the possible different directions of movement, i.e. the manoeuvrability of a machine, but especially its response time. An agile machine is therefore able to implement incoming commands with little loss of time.

Ambient temperature

The ambient temperature is an important factor when designing a hydraulic scissor lift . It is not so much the current temperature that is important, but rather the extremes between positive and negative temperatures.
In extremely cold or hot ambient temperatures, the lift table must be prepared for its use by means of appropriate additional equipment. Oil coolers and oil heaters can be used to ensure that the hydraulic oil is within the permitted operating temperature range.

Angle of rotation encoder

An angle of rotation encoder is used to record the angle of rotation of a component and convert it into an electrical signal. This signal is often connected to a programmable logic controller. The value is then used for a control chain or control loop in the program.

Angle of rotation encoder are seldom used in scissor lift tables . They are advantageous to use if a rotating platform needs to be positioned fully variably or in small steps, for example. Angle of rotation encoders are more frequently used in a draw-wire encoder to actuate a defined lifting height.


A combination of several parts can be called an assembly. This term is usually used when the individual parts/sub-assemblies are inseparably connected or when there is a functional connection.

This can easily be illustrated by the various assemblies of a scissor lift table:

Inseparable assembliesFunctional assemblies
Base frame Control system

Axial forces

Axial forces are forces that act in the direction of an axis.
When components are designed, the coordinate system is usually adapted to the geometrical shape of the component. Forces that do not act in the direction of the x, y or z axis can be broken down into axial forces using the trigonometric functions.
