Operation diagram of articulated boom lift
To operate articulated boom lift, the first step is to understand the various buttons of the aerial work platform, and equip the end of the telescopic and rotating arms of the articulated boom lift vehicle with a self-propelled hydraulic lifting device for the work platform. The main operator control station is located on the platform, as shown in Figure 1.
The operator can use this control station to drive and turn the articulated aerial vehicle forward or backward. The operator can raise or lower the upper and lower arms of the boom, or rotate the boom to the left or right. The standard boom rotates 360 degrees to the left and right of the storage position.
The articulated boom lift aerial work platform ground control station, as shown in Figure 2, can be changed to ground control when the platform control station fails. Ground control can operate the lifting and rotating actions of the boom, used to lower the platform to the ground in emergencies when the operator on the platform is unable to operate. Ground control can also be used for pre-start checks.
Ground control station for articulated boom lift
The boom lifting, rotation, platform leveling, boom extension, platform rotation, auxiliary power supply, tower arm extension, tower arm lifting, and forearm control switches are spring-loaded and will automatically return to the neutral (closed) position when released.
If equipped with a function authorization switch, this switch must be held down to operate functions such as boom extension, tower boom lifting, turntable rotation, boom lifting, jib lifting, platform horizontal positioning, and platform rotation. The following is a detailed introduction to each module:
1. Platform rotation
When placed in the left or right position, the platform rotation control switch can provide platform rotation.
2. Platform leveling
Allow the operator to adjust the 3-position switch of the automatic self leveling system. This switch is used to adjust the platform level in situations similar to uphill/downhill. The platform leveling function can only be used for minor leveling of the platform. Incorrect use may cause the load or personnel to move or fall. Violating this warning may result in death or serious injury.
3. forearm (if equipped)
When the forearm control switch is in the up or down position, it provides the function of raising or lowering the forearm, respectively.
4. Power/emergency stop switch
Two red mushroom switches, when pulled out (ON), can provide power to the platform/ground selection switch. When pressed (OFF), the power to the platform/ground selection switch will be turned off. When the power/emergency stop switch is in the “ON” position and the engine is not running, the alarm will sound and display the ignition switch as “ON”. When shutting down, the main control/emergency stop switch must be switched to the “OFF” position to prevent battery discharge.
5. Engine start/auxiliary power switch or engine start/auxiliary power switch/function authorization
When starting the engine of the articulated boom lift high-altitude work vehicle, keep the switch “up” until the engine starts. If you want to use an auxiliary power supply, this switch should always be kept “down” during the use of the auxiliary pump.
The auxiliary power supply can only be used when the engine is not running. If equipped with an authorization switch, the authorization switch must remain “down” during engine operation in order to activate all boom controls. The auxiliary power supply only operates without engine oil pressure and is disabled when the engine is running.
Due to the much smaller supply flow of hydraulic oil, the operation of various functions will be slower than normal. When using an auxiliary power supply, do not operate more than one function at a time. (Synchronous operation may cause overload of the auxiliary pump.)
6. Tower arm extension and retraction
When the tower arm telescopic control switch is placed in the IN or OUT position, it can control the extension and retraction of the boom. This function only works when the tower arm is fully raised (raised). To avoid overturning and serious injury, do not operate a articulated boom lift high-altitude work vehicle if the tower arm lifting and telescopic functions are not operated in the above order.
7. Timer
A timer installed at the bottom of the ground control box records the duration of use and engine operation of the articulated boom lift aerial work vehicle. By connecting the oil pressure circuit of the engine, only the time of engine operation is recorded. The maximum value of the timer is 9999.9 hours and cannot be reset to zero.
8. Platform/ground selection switch
When the 3-position key-operated switch is turned to the “platform” position, it will provide power to the platform console. When the switch key is in the “ground” position, the platform power will be turned off, and only ground control can operate. When the platform/ground selection switch is in the middle position, the power supply to the control devices of both operating stations is turned off.
9. Rotation control
When the rotary control switch is placed in the “right” or “left” position, it can provide 360 degree continuous turntable rotation. When operating the boom, ensure that there are no personnel around or below the platform.
If any control handle or toggle switch that controls the platform action does not return to the function off (OFF) position after being released, to avoid serious injury, do not operate the curved arm high-altitude work vehicle. To avoid overturning and serious injury, do not operate a curved arm high-altitude work vehicle if the tower arm lifting and telescopic functions are not operated in the above order.
10. Tower arm lifting and lowering
When the tower arm lifting control switch is placed in the down or down position, it can control the lifting and lowering of the tower arm. This function only works when the tower arm is fully retracted (contracted).
11. Boom lifting control
When the boom lifting control switch is placed in the down or down position, it can control the lifting and lowering of the boom.
12. Boom telescopic control
When the boom control switch is placed in the IN or OUT position, it can control the extension and retraction of the boom.

2. Driving alarm horn
After pressing the manual horn switch, power can be supplied to the sound alarm device.
3. Boom lifting/rotation controller
Proportional dual axis control handle for boom lifting and rotation. Push forward to rise; Pull back to lower. When pulling to the right, rotate to the right; When pulling to the left, turn to the left. The functions of lifting and rotating the upper arm can be combined and selected. When two functions are selected simultaneously, the maximum speed will decrease.
4. Boom extension control
When the boom control switch is placed in the “retracted” or “extended” position, it can control the extension and retraction of the boom. The boom lifting, rotating, and driving control handles are designed with spring pressure, and can automatically return to the neutral (OFF) position when released.
5. Driving/steering

The articulated boom lift walk & drive
Function speed control
Control the speed of the boom and rotation function. Rotate counterclockwise to slow down the speed; Turning clockwise can accelerate the speed. To switch to slow mode, turn the knob all the way counterclockwise until you hear a click.
Driving speed/torque selection
The driving speed/torque selection is a three-position switch. The forward position can provide the highest driving speed by switching the drive motor to the minimum displacement and reaching high engine speed when the drive control lever is moved.
The backward position can provide the maximum torque required for rough terrain and hill climbing by switching the wheel motor to maximum displacement and reaching high engine speed when the drive control lever is moved. The middle position can keep the engine in a medium-speed state and switch the driving motor to the minimum displacement or fastest speed to make the operation of the articulated boom lift as quiet as possible.
Platform rotation
The operator can rotate the platform to the left or right through this switch. The platform leveling function can only be used for minor leveling of the platform. Incorrect use may cause the load or personnel to move or fall. Violating this warning may result in death or serious injury.
Platform leveling
Allow the operator to adjust the 3-position switch of the automatic self leveling system. This switch is used to adjust the platform level in situations similar to uphill/downhill.
forearm (if equipped)
When the forearm control switch is in the up or down position, it provides the function of raising or lowering the forearm, respectively.
Fuel selection (dual fuel engines only) (if equipped)
Move the switch to the corresponding position to select gasoline or liquid propane fuel. There is no need to clean the fuel system when switching fuel, so there is no waiting time when switching fuel while the engine is running.
Work lighting (if equipped)
When the articulated boom lift is equipped with work lighting, the switch on the lighting can be operated. The power/emergency stop switch must be turned on (mushroom-shaped button pulled out), and the ignition switch does not necessarily need to be turned on when operating the lighting. Therefore, it is important to avoid running out of battery power when left unattended. The main switch and/or ignition switch on the ground console can turn off the power to all lighting.
Steering selection (if equipped)
When equipped with 4-wheel steering, the operator can choose the action of the steering system. When selecting the center position of the switch, perform regular front wheel steering while the rear wheels are not affected. This is the optimal position for normal driving at maximum speed. The forward position is used to select the “crab turn” direction.
In this steering mode, the front and rear axles will turn in the same direction, allowing the chassis to move to one side while driving forward. Can be used to position the curved arm high-altitude work vehicle onto the aisle or adjacent to buildings. The backward position is used to select “collaborative” steering. In this mode, the front and rear axles turn in opposite directions, minimizing the turning radius of the articulated boom lift when maneuvering in narrow areas.
There is a label on the top of the switch that indicates the desired wheel movement mode through the position of the switch. To resynchronize the front and rear axles, press and hold the steering switch (control rocker switch) until all steering cylinders are at their end of travel. This step can be completed in either crab mode or collaborative mode.
Auxiliary power supply
Press forward, this switch will power up the starting motor to start the engine. Press backward to power up the electric hydraulic pump (if activated). During the use of the auxiliary pump, the switch must remain ON. When the main pump or engine malfunctions, the auxiliary pump function can provide sufficient oil flow for operating the basic functions of the articulated aerial vehicle. The auxiliary pump can operate functions such as tower arm lifting, tower arm extension, boom lifting, boom extension and rotation.
Tower arm extension and retraction
Three position toggle switch, with the middle position closed. When placed in the down or down position, it can control the lifting and lowering of the tower arm. Before operating the tower arm extension and retraction, the tower arm lifting function must be fully raised. When the tower arm is extended, the lifting function of the tower arm should be invalid.
Tower arm lifting and lowering
Three position toggle switch, with the middle being closed. When placed in the inward or outward position, it can control the extension and retraction of the tower arm. Before operating the tower arm lift, the tower arm extension function must be fully retracted. When the tower arm does not reach the “fully raised” state, the tower arm extension function should be invalid. To avoid overturning and serious injury, do not operate a curved arm high-altitude work vehicle if the tower arm lifting and telescopic functions are not operated in the above order.
