Capacity loads may be handled for initial installation of equipment and for infrequent maintenance.
CLASS M4 – LIGHT SERVICE
This service covers cranes which may be used in repair shops, light assembly operations, service buildings, light warehousing, etc., where service requirements are light and the speed is slow. Loads may vary from no load to occasional full-rated loads with two to five lifts per hour, averaging ten feet per lift.
