De Haan Special Equipment produces a wide range of crane blocks, which can be used for various types of operations. The crane blocks meet all the requirements that apply to lifting operations in countries where the blocks are used. For example, the blocks can be used:
- As simple blocks that are mounted onto a crane long-term.
- As blocks with speed reeve for quick reeving or yawing.
- As special blocks with removable ballast parts, which are used primarily in the construction of windmills.
- Or as a specialised method that custom work applies to.
For offshore purposes, the crane blocks are available as underwater model with seal.
