STEEL MINE TIESSteel ties have a decided advantage over wood ties in mining applications. They hold the rails securely, keeping them true to gage and the track in alignment. They have unusually long life, even under severe service conditions, and can never become spike-killed or rotted. Also, they are not a ˜re hazard.The ties are light compared to wood. One man can easily handle a bundle of ˜ve ties. The ties are relatively shallow in section, thereby saving valuable head-room in low seams. The heavier ties are sometimes used for main-haulage tracks, and are often used in conjunction with wood ties in place of gage rods, by spacing them between every third or fourth tie. By adding a steel tie at 6 feet to 10 feet intervals, the service of wood ties will be prolonged through relief of strain during the early period of decay.To provide even greater strength, steel ties can be supplied that are bolted to a wood base. The base is grooved (so that it will ˜t up under the tie) and bolted securely to the tie. Oak is usually used, and it can be treated or left untreated.Installation of Steel TiesThe installation of steel ties with riveted clips is simple and easy. Whether the ties are straight or upset end, they are installed in the same manner. No gaging of track is required. 1. The rail is placed on the tie, in position against the stationary clip. 2. Blows of a hammer turn the movable clips into position over the rail base. 3. The clips hold the rail ˜rmly in place, to accurate gage. STEEL MINE TIESSteel Ties with Outside Stationary ClipsIn all sections the most widely used tie is the outside stationary clip tie. It is equipped with fourrolled-steel movable clips, and two stationary clips placed on the outside ends, as illustrated. The clips are spaced to ˜t one particular rail section.Steel Ties with Staggered ClipsAlso available is the staggered clip tie, which is equipped with four rolled-steel movable clips and two stationary clips, with a stationary clip on the inside at one end, and on the outside at the other end. This feature is especially useful when it is desired to insert or remove a tie without disturbing the track gage. The clips are spaced to ˜t one particular rail section.Tunnel TiesTunnel Ties are speci˜cally designed for use in tunneling projects where the bottom surface is not ˚at. These ties can be used without blocking and will maintain proper track gage. Each tie is designed speci˜cally to meet the requirements for a particular job. Customers should specify the tunnel diameter, wheel load, and tie spacing. The design speci˜cations are reviewed by an engineer to ensure tie construction will support the wheel loads required for a given project. Axle loads of 45,000 lbs on 30 inches tie spacing have been successfully implemented. STEEL MINE TIESShown on this page are some of the most common steel tie sections available today. Although the table below gives some general recommendations, there are several factors to be considered in choosing a steel tie. These include condition of the bottom, weight of cars and equipment, amount and speed of traf˜c, permanency of trackage, and weight of rail. 5-1/4 inches 5/32 inches 1-3/32 inches 5-1/4 inches 11/64 inches 1-3/32 inches 5-11/32 inches 13/64 inches 1-1/8 inches 2 inches 1-3/4 inches 5-7/8 inches 3/4 inches T-4 T-6 T-9 T-5 Drawings shown to scaleNot actual size Tie Section Weight Rail Section T – 4 3.85 lbs/ft 30 - 60 lb T – 5 5.0 lbs/ft 30 - 60 lb T – 6 6.0 lbs/ft 40 - 85 lb T – 9 10.5 lbs/ft 60 - 100 lb
