Control elements of a work platform simply explained

Zusammenfassung

Safe operation of a mobile elevating work platform requires in-depth knowledge of the controls.From lifting, lowering, swiveling to tilting – every control element on the control panel has a clear function.Modern stages usually work with digital control, color-coded directional arrows and offer additional functions such as automatic support legs or emergency stop switches.

Important measures for safe operation include instruction by qualified personnel, dry runs and studying the instructions.Only those who understand the controls and practice regularly can work efficiently and safely at height.

Operating aerial work platforms requires a thorough understanding of the various controls required for safe and efficient operation of the equipment. Whether it's a scissor lift, articulated boom lift, or telescopic boom lift, each platform has a specific control panel that the operator must master to safely navigate the aerial access equipment.

In this guide, we'll cover the basic controls found on most aerial work platforms, as well as some advanced features available on more modern models. We'll also provide tips and tricks to help you quickly become familiar with these controls and feel confident using them.

Basics of control: similarities and differences

The controls are the heart of any aerial work platform, allowing the operator to operate the machine safely and efficiently. There are different types of aerial work platforms, and while each has its own specific control features, there are also some similarities in how they are operated. Most aerial work platforms have a set of basic controls required to operate the machine. These include levers or joysticks for vertical and horizontal movement, buttons or switches for raising and lowering the platform, and emergency stop buttons for emergencies.

Different approaches to control

Depending on the type of aerial work platform—be it a scissor lift, an articulated boom lift, or a boom lift—the specific controls and their layout can vary. For example, scissor lifts often have simpler controls, as their movements are typically limited to up and down movements and driving. Truck-mounted, articulated boom lifts, and boom lifts, on the other hand, have more complex control systems that allow for greater freedom of movement.

Digital versus analog control

Modern aerial work platforms typically use digital controls, which allow for more precise control and often offer diagnostic features. Older or simpler models may have analog controls, which are less complex but also less accurate.

Marking and symbols

The controls of aerial work platforms are usually identified by symbols and colors to facilitate operation and avoid misunderstandings. Knowing the meaning of these symbols and colors is essential for safe operation.

The control panel: your command center at height

The control panel is the central interface between the operator and the aerial work platform. It is the "command center" from which all movements and functions of the machine are controlled. Not only are the height and position of the work platform adjusted here, but important safety functions are also monitored and controlled.

The control panel is generally designed and arranged for intuitive operation. Important functions are easily accessible, and the controls are clearly labeled to prevent incorrect operation. The specific layout and design may vary depending on the model and manufacturer, but the goal is always simple and safe operation.

From lifting to panning to tilting: These are the controls you should know

The controls on a boom lift's control panel are critical for safe and efficient operation. They enable a variety of movements and functions required for different tasks. Here are some of the most important controls and their functions you should know:

Engine control

Starting the engine is the first thing the operator must do to operate a diesel or hybrid aerial work platform. Pressing a key switch or start button activates the engine, which in turn supplies power to the aerial work platform's hydraulic and electrical systems. Starting the engine is therefore the first step in activating the aerial work platform and making its controls functional. Before starting the engine, the operator must ensure that the area is safe and that all of the aerial work platform's systems are functioning properly. Some modern aerial work platform models are also equipped with start-stop systems that automatically shut down the engine when the aerial work platform is not in use and restart it when the operator operates the controls. This helps save fuel and reduce emissions while keeping the machine ready for use.

Raise and lower

The primary function of a work platform is to raise the operator and their tools to the desired height. Buttons or levers for raising and lowering are therefore central elements of the control panel.

Sway

The swiveling of the work platform allows the operator to change the orientation of the work platform without changing the position of the base. A swivel lever or knob enables this lateral rotation.

Tend

The tilt function allows the platform to be tilted to a specific angle for working in hard-to-reach areas. This special platform orientation is made possible by a tilt controller.

Direction of rotation switch

The direction of rotation switch, often in conjunction with the joystick, allows the operator to change the direction of rotation of the work platform.

Exiting and retracting

Especially with telescopic and articulated boom lifts, the arms can be extended and retracted to increase or decrease the reach. This is usually controlled by separate controls on the control panel.

Support leg extension

Some aerial work platforms feature extendable outriggers for additional stability. The controls for operating the outriggers are also located on the control panel.

Emergency stop switch

The emergency stop switch is a critical safety mechanism that quickly stops the machine in an emergency.

Signal horn

The signal horn, also called a horn or horn, is used to alert other people on the construction site to the movement of the aerial work platform.

Additional control functions

Depending on the model and manufacturer, additional control functions such as cruise control or special safety locks may be available.

Color-coded arrows: Your guide in the right direction

When working at height and performing various movements, it's easy to lose your bearings. The colored directional arrows on the joystick and the arrows on the work platform ensure intuitive and safe control.

The joystick has a different colored arrow for each direction, for example, yellow or blue. These colors correspond to the colored arrows on the aerial work platform. The colored arrows on the aerial work platform clearly indicate the direction the aerial work platform will move when the joystick is pushed in the direction of the corresponding color. For example, if you move the joystick towards yellow, the aerial work platform will move in the direction of the yellow arrow on the platform. This color coordination helps you maintain control and safely execute the desired movement, even if you don't know which way the platform is facing.
