This video is intended for loader crane operators and provides step-by-step instructions on safely starting their HIAB loader crane.
Placing the vehicle
General case:
Place the vehicle on a flat surface. The vehicle inclination (α) during crane operation must not be more than allowed in the Technical Data for your crane.
To determine the inclination of the truck, check the spirit level on the crane. When the bubble is in the middle of the gauge, the crane is in horizontal position. When the bubble is between the two circles, the crane inclination is between 0° and 5°.
If the slope exceeds the permitted inclination, unintentional crane movements can occur.
Working with boom system beyond 60°
To avoid side deflection and in order to guarantee the safest operation when working with e.g. Lifting Accessories and/or Hoist applications, the vehicle has to be completely levelled in any direction (α=0o).
NOTE:
• Operating the crane in to and out of transport position must also be done with the vehicle completely levelled.
• Activate the parking brake and place chocks under the wheels to prevent vehicle movement.
Start the safety system
The operating levers must be in the neutral position before start up.
To start the safety system, press the On/Off button . The LED above the button lights up. The system will check itself. (2-4 seconds)
The warning lamps on the stabiliser legs light up.
Engage the PTO
Engage the PTO (Power Take Off) and bring the vehicle engine to the correct rpm.
Rpm too high: the oil in the hydraulic system might overheat.
Rpm too low: during crane operation, the vehicle engine could stall.
• The maximum rpm may depend upon a governor on your PTO combination.
Start the control system
The operating levers must be in a neutral position before start up. To start the control system, push the On/Off button on the user panel.
The LED above the button lights up. The system will check itself for a few seconds. The warning lamps on the stabiliser legs light up.
Start the controller
1. Fasten the controller to a waist belt, or shoulder-/neck strap, in the most comfortable operation position. The Stop button should be on the right hand side.
2. Push button on the user panel. The LED above that button will blink.
3. To activate the controller, pull out the emergency stop button by turning it clockwise. The LED above the remote button becomes steady and the warning lamps on the stabiliser legs blink.
Indications XSDrive
The first LED in the LEDs menu starts blinking. When communication has been established, the LED will give a steady light = ready for use.
Set the stabiliser system
To ensure the maximum stability of the vehicle, all the stabiliser extensions and legs must be fully extended and set to the ground without lifting the wheels from the ground.
• Cranes with VSL: when the stabiliser extensions are not fully extended, the lifting capacity is optimized by the VSL feature to ensure the maximum stability of the vehicle.
• Cranes without VSL: crane must be operated with the stabiliser extensions fully extended and the stabiliser legs set to the ground without lifting the wheels from the ground, otherwise the stability of the vehicle will not be ensured.
Stability sector indication
The operator must have a full view of the stabiliser system when operating it. To confirm a full view of the stabiliser system, button is pushed on the user panel on the side where the stabiliser system is going to be operated. As soon as the button has been pushed, the LED for the active stabiliser leg will light green.
• Cranes with VSL: the stability sector LEDs will indicate the crane capacity in six different
sectors due to stability. The stability sector indication will change according to the stabiliser
system position.
• Cranes without VSL: the stability sector LEDs will light green regardless of the situation. The operator is the responsible to make sure that the vehicle is stable while lifting a load.
Stabiliser system and ground conditions
Always:
• Make sure that the ground can support the load that the stabiliser leg imposes on the ground. Check that the extra support plates do not bend or sink into the ground. Lower the stabiliser legs only on to a flat, firm and stable surface.
• Make sure that the ground is not undermined.
• Use the extra support plates that are large and firm enough for your crane model.
The maximum permitted ground inclination under the stabiliser leg plate is 5 degrees.
Extend the stabiliser extensions, Activate the stabiliser system, and Set the stabiliser legs
The procedure of setting the stabiliser extensions differs depending on the type of stabiliser
extensions. Repeat the instructions for the stabiliser extension on the other side of the vehicle. For auxiliary stabiliser system [option]: Repeat the process.
1. Make sure that the stabiliser extensions are extended.
2. Operate the stabiliser leg downwards until it is set to the ground.
