A hopper is usually a funnel-shaped attachment used when filling silos, containers or bags with bulk materials (e.g., sand, gravel, pellets, cement).
In the context of lifting, a hopper can be part of a structure used to deposit bulk goods in a controlled manner.
A traverse (also called a lifting beam or spreader beam) is a lifting device that distributes the load to multiple lifting points.
Often used to:
Lift large, long or heavy loads stably.
To prevent a load from deforming or hoisting belts from being at too sharp an angle.
Types of traverses:
Rigid beam traverses.
Adjustable traverses.
Spreader traverses (with chains or cables).
Collective name for all devices needed to attach a load to a hoisting or lifting device.
Examples:
Hooks, shackles, fasteners (shackles).
Hoisting belts, chains, steel cables.
Vakuum lifters, magnetic lifters, grippers.
Traverses (are also included here).
👉 Summary:
A hopper = attachment to guide bulk material.
A traverse = special beam/spreader for safe lifting of wide or heavy loads.
Load lifting means = all means necessary to connect the load to the crane or hoist.
