Truck-mounted

Aerial work platform so-called aerial device uses many position sensors.

1. Boom

For the purpose of operating the telescopic boom within the safety angle range to avoid the overturning of the vehicle by the weight of the boom and the aerial platform, many position sensors are installed on the telescopic boom. 

a. Boom Length
The multi-turn position sensor is used for the detection of boom length of the telescopic boom.

 

 

 

 

 

 

b. Boom Angle
For monitoring and detecting the operating angle of the boom, inclinometer or angle sensor is used.

CP-22H Gear Head Series Multi-Turn Position Sensor

CPP-45 Gear Head Series Multi-Turn Position Sensor

CP-45FB Series Angle Sensor

CP-2FABSJ Series Angle Sensor

CP-2HA Series Angle Sensor

CP-1Hx Series Angle Sensor

CP-3HABS Series Angle Sensor

74 Series Inclinometer

PMP-HTL Series Inclinometer

WR Series Inclinometer

ESC30xxZ Series Inclinometer

THD2000Z Series Inclinometer

 

2. Turntable

To determine the operating direction of the boom, the turntable located under the boom mechanism is rotated. the multi-turn position sensor or angle position sensor are used to measure the rotation angle or the number of rotations of the turntable.

Sensor Example

CPP-45 Gear Head Series Multi-Turn Position Sensor

CP-45H Gear Head Series Multi-Turn Position Sensor

CP-45FB Series Angle Sensor

CP-45H Series Angle Sensor

3. Outrigger

Moreover, by using the outriggers that are installed at the for corners of the vehicle, it increases the stability of the vehicle and expands the safe operating area of the telescopic boom.
The linear position sensor or inclinometer is used to monitor/ measure the drawer position of the outriggers.

 

4. Vehicle Body

In addition, monitoring the inclination of the vehicle itself would increase the stability of the vehicle and increase the safety of the workers who are working within the aerial platform.
The inclinometer has been installed as the overturning prevention device of the vehicle.

Sensor Example

74 Series Inclinometer

ESC30xxZ Series Inclinometer

THD2000Z Series Inclinometer

 

5. Platform

a. Platform control box/ Control foot pedal
Workers are able to operate the height, the direction, and the operating speed of the boom from the platform by using a control box and control foot pedal installed on the platform.
Angle sensors are installed in the joysticks of the control box for measuring the angle of the lever and the stepping angle of the foot pedal.

b. Platform Pan/Tilt
The platform is able to be rotated horizontally during operation and move vertically to remain the platform horizontally or when it is at the stored state during non-operation.
To monitor the platform’s angle, the angle position sensor or the multi-turn angle position sensor is used.
