What is the different types of machine moving skates?
Based on the provided context, there are at least three different types of machine moving skates:
1) Straight-line skates: These skates are designed for moving loads in a straight line and are typically fixed in place.
2) Swivel skates: These skates allow for more maneuverability and can be used for turning and moving in tighter spaces.
3) Tilting skates: These skates are designed for use on uneven or rough surfaces and can adjust to maintain stability.
The context also mentions that there are skates for "multidirectional needs", but it doesn't specify what type of skate this refers to. It's possible that this refers to a combination of swivel and tilting skates, or a different type of skate not explicitly mentioned.
