NER M & C Speed Conversions
From NER020M to NER030C
and from NER030C to NER020M
Purpose:
To provide instructions and lists of the parts required to convert between NER020M and NER030C
hoists. The conversions involve changing between single (020M) and double (030C) fall configurations.
Application Information:
•
For other 020M and 030C mounting configurations, use the parts above omitting the Top Hook
Assembly (Page 56, Figure No. 8) then follow EDOC0049 to identify the additional Kit/parts required.
•
Converting a chained hoist from a 020M to a 030C will cut the lift on the hoist in half. Converting a
chained hoist from a 030C to a 020M will double the lift. Depending on the application, the push
button pendant drop may need to be changed (not included in the scope of this document).
•
When converting pre-chained units or hoists in the field, it is necessary to remove and reinstall the
load chain so that the end links are correctly oriented. Harrington strongly recommends for field
conversion to be performed by a repair center or experienced/qualified distributor because of the de-
chaining and re-chaining of the hoist.
