A quick release mechanism for a wheel includes a hub and a clip, which interact with a wheel or roller that may or may not be part of the invention per se. The hub is disposable on a drive shaft such that it will rotate with the drive shaft. An optional hub cap is disposable on the wheel and has an opening that is complimentary to the geometry of the hub to allow engagement thereof such that the hub the hub cap rotate together. The clip is disposable on the hub in a closed or an open position so that the hub cap cannot or can be removed from the hub.

A connection system for coupling a steam turbine to a condenser is provided. The connection system includes a dog-bone connector, a first clamp, and a second clamp. The dog-bone connector includes a first end, a second end opposite the first end with respect to the third direction, and a body extending therebetween. The first clamp includes a first portion, a second portion coupled to the first portion, and a first retention cavity defined therebetween. The first clamp is configured to couple to one of the steam turbine and the condenser such that the first portion is movable relative to the second portion along the third direction. The second clamp is configured to couple to the other of the steam turbine and the condenser and includes a third portion, a fourth portion coupled to the third portion, and a second retention cavity defined therebetween.

A cable hook for fixing a rebound mat to a trampoline frame by means of two elastic elements and at least one flexible strap element has a housing with four receivers, wherein each elastic element has two free ends, each of which has a clamping element enlarging the periphery of the elastic element. A clamping element is inserted in each receiver. The cable hook has a cable hook body which is closed in the peripheral direction transversely to the fixing direction, wherein in each case two receivers are separated centrally by a receiving cavity in the cable hook body through which a clamping element can be passed. The cable hook has two terminating pieces which can each be inserted in a respective receiving cavity, and each has a cover rounding pointing away from the cable hook housing and oriented towards each other.

A system for providing safety to a hoist having a hook and a chain. The system includes a safety cable threaded through an opening of the hook or an object to be lifted. The system includes a connector connected to the safety cable and the chain such that when the hook and the chain of the hoist are disconnected, the object remains connected to the chain via the connector and safety cable. The connector includes a base portion having a chain opening configured to receive the chain, and a first cable opening configured to receive the safety cable. The connector includes a top portion configured to be coupled to the base portion and cover a portion of the chain opening such that the base portion and the top portion, when coupled together, remain at a substantially fixed position along the length of the chain.

A cutting device support for a mining machine includes a ranging arm, a bracket positioned adjacent an end of the ranging arm, and a thermally-expandable coupling member positioned between the bracket and the ranging arm. The coupling member exerts a force on the bracket and the ranging arm to secure the bracket to the ranging arm.
