If the Alimak Scando 650 Series does not lift when starting in the Up direction, follow these steps:

1. Check if the contactors oscillate on and off ("shatter") when starting with a full load.
2. Inspect the contacts of the Up and main contactors for damage.
3. Measure the incoming power supply voltage at both the B-panel at the base and the M-panel in the car during starting conditions with a rated load.
4. Determine if the voltage drop exceeds acceptable values.
5. If a voltage drop issue is identified, increase the conductor size in the power supply cable from the job site distribution.

These steps help diagnose and resolve voltage drop problems affecting the hoist's operation.

Transportable foundation In order to use a transportable steel foundation, the following requirements must be met: – The steel foundation must conform to all of Alimak’s specifi- cations. (These can be ordered separately from an Alimak representative). – The type of installation must be approved by the local gover- ning authorities.

The selection of ties depends also on the length of tie required tie distance. For detailed specifications see heading ”Mast ties”. 4. Numbers of mast ties Determined by tie distance and overhang at various maximum lifting height. See tables in the end of chapter. ALIMAK 34796 - 1/01...
Page 110 As can be seen from the following tables this is only necessary at extremely high lifting heights. In such cases turn to Alimak Calculation Department who can optimize the installation so that as few reinforced mast sections as possible need to be used.
Page 111 A transition section or a reinforced mast section must always be used for connection against bottom frame. A transition section must always be used between mast sections with different tube thicknesses. Reinforced mast sections must always be placed at the bottom of a mast installation. ALIMAK 34798 - 1/01...
Page 112: Mast Ties
If you intend to use embedment anchorings, these must be prepared well in advance before erection. Note that the wall must always be dimensioned to take up the reaction forces of the ties. ALIMAK 34799 - 1/01...
Page 113: Tied Hoist Mast
If this is not possible an extra tie should be instal- led at the landing. – In cases where required lifting height exceeds the max. allowable mast height, we kindly ask you to contact Alimak for advice. ALIMAK 34800 - 1/03...
