## Abstract

An elevator rail clamping system for coupling to omega elevator rails is disclosed. Each omega elevator rail having a circular portion and a pair of wings extending therefrom. The system including a pair of hinged clamps with each clamp having a pair of jaws for receiving the circular portion of an omega elevator rail. The system further including an adjustable length load bearing beam mounted to each clamp.

## Claims

### Claim 1

An elevator rail clamping system for attached to omega elevator rails having a circular portion and a pair of wings extending therefrom, the system comprising:
a pair of hinged clamps, each clamp having a pair of jaws for receiving the circular portion of one of the omega elevator rails and a nose plate for bolting to the wings of the rail; and,
an extendable length load bearing beam mounted to each of the clamps.

### Claim 2 (depends on 1)

The elevator rail clamping system of claim 1 wherein each clamp has a throat for receiving said omega elevator rail circular portion.

### Claim 3 (depends on 1)

The elevator rail clamping system of claim 1 wherein each clamp has a beam seat extending perpendicularly from the nose plate and a beam securing ear bolted thereto.

### Claim 4 (depends on 1)

The elevator clamping system of claim 1 wherein each clamp includes a roller.

### Claim 5 (depends on 1)

The elevator rail clamping system of claim 1 wherein each nose plate has at least one aperture extending therethrough.

### Claim 6 (depends on 1)

The elevator rail clamping system of claim 1 wherein the load bearing beam includes an I-beam and a pair of extendable ends attached to the I-beam.

### Claim 7 (depends on 1)

The elevator rail clamping system of claim 1 wherein each clamp includes a bolt for limiting travel between the jaws.

### Claim 8

A clamp for attaching to an omega elevator rail having a circular portion and a pair of wings extending therefrom, the clamp comprising:
a pair of hinged jaws for receiving the circular portion of the omega elevator rail;
a nose plate attached to the distal end of each jaw and comprising a web of metal or metal alloy, each nose plate having an aperture extending therethrough; and,
a bolt extending through each aperture and into the wings of the elevator rail.

### Claim 9 (depends on 9)

The clamp of claim 9 wherein the jaws form a throat for receiving said omega elevator rail circular portion.

### Claim 10 (depends on 10)

The clamp of claim 10 further comprising a beam seat extending perpendicular from each of the nose plates.

### Claim 11 (depends on 11)

The clamp of claim 11 further comprising a securing ear attached to each beam seat.

### Claim 12 (depends on 9)

The clamp of claim 9 further comprising a latch arm attached to one nose plate.

### Claim 13 (depends on 9)

The clamp of claim 9 further comprising a latch arm attached to both nose plates.

### Claim 14 (depends on 9)

The clamp of claim 9 further comprising a roller attached to both jaws.

### Claim 15 (depends on 9)

The clamp of claim 9 further comprising a bolt attached to both jaws for limiting travel between the jaws.
