  • Device for mounting and dismounting shaft furnace tymps
    Patent number: 5203063
    Abstract: The device comprises a gripper with retractable claws which can engage through the tymp and control means which pass through the gripper and can be controlled from outside in order to spread or retract the claws radially with respect to the axis of the tymp. The gripper and its control means are carried by a yoke designed to be fitted onto the outer edge of the tuyere arch and to be associated with a conventional pneumatic explosive-actuated tool which can be fitted to the outside of the yoke, either onto extensions of the claws or onto the control means, in order to exert by its rotation and its bearing on the yoke a tractive force on the claws of the gripper.
