5. Transporting and Handling

5.1 Handling the Actuator

5.1.1 Handling the Packed Unit

Unless otherwise specified, each actuator (axis) is shipped individually. Please take care that the shipping box is not dropped or subjected to strong impact during transport.

• The operator should not carry heavy shipping boxes by themselves.

• If the shipping box is left standing, it s hould be in a horizontal position.

• Do not climb on top of the shipping box.

• Do not place heavy objects on top of the shipping box.

5.1.2 Handling the Actuator After It is Unpacked

Lift the actuator up by the base to remove it from the packing.

• When transporting the actuator, be careful not to hit it against nearby structures or object. In particular,

exercise caution to protect the motor unit and pulley case against impact.

• Do not exert excessive force on any part of the actuator.

• Be careful not to cause the cables to receive a tensile force.

Supplement) Please refer to Section 4 above for the names of the actuator parts.

5.2 Handling the Actuator Assembly

Pay attention to the following instructions w hen transp orting an as s e mbly of act ua to r axes.

5.2.1 Condition of Shipment from IAI (Assembled)

The actuators you have ordered are assembled at IAI, after which the assembly receives a shipping inspection and is shipped in an outer frame with skids.

The assembly is packed with the rod securely affixed so that it will not move unexpectedly during transportation. In the case of a combined unit, the actuator ends are secured to prevent swinging due to external vibration.

• The package is not designed with special considerations for protection against impact due to dropping or collision, so please handle the package with care. Also, do not place any heavy object on the outer frame, as it is not strong enough to withstand loads.

• When suspending the package using ropes, etc., pass the ropes from underneath the reinforcement frames at the bottom of the skids. When lifting with a forklift, also place the forks underneath the skids.

• Set down the package carefully so as not to apply impact to the assembly or cause it to bounce.

After unpacking, handle the actuator assembly correctly by observing the instructions given below.

5.2.2 Handling after Assembly with Peripheral Equipment

When transporting the actuators that have been assembled with peripheral equipment either at IAI or on your site, observe the instructions given below.

• Secure the rod so that it will not move suddenly while transporting the actuator.

• If any actuator end is protruding, secure it to prevent swinging due to external vibration.

• If the actuator ends are not secured, do not apply any impact force exceeding 0.3 G during

transportation.

• When suspending the actuator-assembled peripheral equipment using ropes, etc., make sure the ropes do not contact the actuators directly.

• Pass the ropes over appropriate cushion materials, and make sure the loads from the ropes will be received by the base of each actuator.

• Secure the end of the Y-axis using a separate rope to maintain the axis in a stable horizontal position. At this time, be careful not to apply loads on the screw cover.

• Be careful not to allow the brackets, covers and connector box of each actuator to receive loads. Also protect the cables from pinching or excessive deformation.

6. Operating and Storage Environment
