Arm Mode

A number of the special functions of SMARTlift are available while in Arm mode.

• When Arm mode is selected during an operation, the sensors automatically check that the stabilisers are firmly in contact with the ground or a companion trailer. If there is no contact, Arm mode is disabled and a warning sound (the horn) and screen message is displayed
• However, if a stabiliser lifts off the ground during the loading operation, the lift is allowed to continue
• When you select Arm mode for the first time during an operation, the sensors automatically check the trailer camber and elevation. If these are outside safe working parameters, Arm mode is disabled and the screen messages below are displayed appropriately.. It may be possible to correct the trailer camber using the stabilisers

• Offside Stability Alarm: If the lifting G-Pin is within 250mm of the trailer centre line on the stabiliser side and the base of the container is higher than the top of the offside bash plates, the offside alarm is engaged. Bottom Arm Down and Top Arm Up functions are disabled. Below this height, the offside bash plates will prevent the container from going too far offside. The SMARTlift system also engages the offside alarm if the G-Pin crosses the centre line of the trailer while loaded.

  

• The pressure in the top arm cylinder is also measured, which enables the system to estimate the mass on the lifting pin. This value is displayed to the nearest tonne whenever the Sidelifter is in Arm mode
• If the road elevation is such that one end of the Sidelifter trailer is higher than the other then the system will allow the high end of the container to be lifted higher than offside bash plate height, so that the container can be placed on the twist-locks
• When lifting two 20-foot containers together it is sometimes necessary to gain extra height above the offside bash plates to position the containers over the centre twist-locks. To gain extra height, press the horn button on the remote, once to override the SMARTlift height limitation. The SMARTlift system will then beep once in reply. A message on the LCD display screen confirms that Double Twenty mode is operational. The SMARTlift system will stay in Double Twenty mode until either the engine is switched off or the horn button is pressed once. This procedure only works when the Sidelifter is in Arm mode.
• Each crane Electrical Control Unit (ECU) calculates the position of the stabiliser foot and the position of the lifting G-Pin. When the G-Pin is extended beyond the stabiliser foot (K-Pin), the system calculates the stability of the Sidelifter on the loading side. As the G-Pin is extended the system first warns that an unstable situation is imminent. See screen message below.

  

• If the operator carries on, the system disables the functions that increase the distance of the G-Pin from the trailer and displays the screen message shown below.

  

• If the stabiliser is very steeply angled and the container is very heavy, then the SMARTlift system may prevent the G-Pin from even being extended beyond the K-Pin.
• The diagram below shows a situation where a container has been unevenly loaded on the side nearest the Sidelifter.

• During loading it is necessary for the operator to:

  a) lift the container higher than normal above the twist-locks and

  b) move the G-Pin further over the offside than normal.

• These situations can cause the SMARTlift offside protection to activate earlier than desired. There are three ways to work around the issue:
  1. Move the Sidelifter and pick the container up from the other side.
  2. Shorten the chains so the container can be lifted higher.
  3. If in the experience of the operator it is safe to attempt the lift, then via the LCD display screen enter the Single Lift manual override PIN provided with this manual. This will allow you to override the SMARTlift system for this one operation only.
