Batch spear holders and safety chucks are manufactured by Norman G Clark in Australia. These safety chucks are suitable for use in applications with repituous winding or unwinding of flexible material. The shafts used in such applications must have square ends of a size to fit the mouth of the batch spear holder.
The batch spear holders from Norman G Clark provide complete support and drive of the roll. The mouth of the batch spear holder can be opened for loading or unloading when it is in the uppermost position, ensuring safety and speed of operation.
The mouth of the batch spear holder closes automatically and locks the shaft in place on commencement of rotation in either direction.
The advantages of Norman G Clark’s BSH safety chucks include:
- Safety lock for maximum protection of machine and operator
- Easy handling during loading and unloading
- Standard shaft extension to mount Horton/Air Champ clutches and brakes
- Rugged construction with all wearing surfaces of hardened steel
