11. Operate the hoist several times up and down (without a load) for the entire length of the lift.
12. Repeat with increasing loads
13. Inspect for twist while operating the hoist. Severe twist will cause the bottom block to turn. This is easily
noticeable when there is no load on the hook. Always make sure that the rope is free of twist prior to
lifting a load to prevent permanent distortion, rope damage, or rope guide damage.
14. If the wire rope has twisted, repeat steps 1-10 until twist is no longer present.
6.7 Storage
6.7.1 The storage location should be clean and dry.
6.7.2 Care should be take to not damage any of the electrical power cords or fittings.
6.8 Outdoor Installations
6.8.1 For trolley and hoist installations that are outdoors, the trolley and hoist MUST be covered and protected from
the weather at all times.
6.8.2 Avoid trolley hoist oxidation by using suitable treatment and lubricating all mechanisms.
6.8.3 Possibility of corrosion on components of the trolley increases for installations where salt air and high humidity
are present. The hoist and trolley may require more frequent lubrication. Make regular inspections of the unit's
condition and operation.
6.8.4 For hoist installations where temperature variations introduce condensation into the hoist additional
inspection and more frequent lubrication may be required.
6.8.5 Refer to Section 2.1.3 for allowable environmental conditions.
