ABSTRACT:
A machinery locating device comprising power-activated clamps which are restrained within a housing and which engage with one or more adjustably positioned stops. The clamps are secured to a moving piece of machinery such as a crane and the stops are secured to a fixed structure. When the clamps are open, the machinery can move freely past the stops. When the clamps are closed on the stops, the machinery is accurately positioned with respect to the structure. Interlocking is provided to insure that the machinery drive is disconnected before the clamps may be applied to the stops, and to insure that the clamps are opened before the machinery drive may be engaged.
The locating device is especially suited to the accurate, repetitive positioning of massive moving machines such as travelling cranes, charging machines for the coke ovens and so forth.
