Our 3H Quick-Change System allows for very quick installation and removal of the Trailer Cage. Guide rollers All Skips can be fitted with a full range of FLSmidth Guiding systems to suit all applications and conditions ranging from economical long lasting Heavy-Ply, fixed rollers for slower speed to High Speed Aircraft tires with spring coil over gas-charged Cylinder suspension. Several sizes and types of tires including Pneumatic, Solid Rubber, Foam-Filled, and solid Polyurethane are available. The wheels are mounted on Steel, Aluminum, or Stainless hubs and brackets with either fixed, serrated, or eccentric axle adjustments. Selection Contact us and advise us of your operating conditions and we will help you pick the best Skip type, Material, Guiding System, and Safety Mechanism to economically suit your application. Solid modeling ensures all clearances and interferences are considered at the “design” stage. 8 Cages Our cages range from very small Two-Man Auxiliary Cages and Trailer Cages to Multi-Deck Cages handling 300 men or more, or internal loads of trucks, equipment, and material of 50 tons or more. Guide Slippers service-able from inside the Cage, Safety Dogs and FLSmidth installed Customer’s Hydraulic Chairing Device. 9 Custom designed (Top) BMR Cage Varying conditions found at installations throughout the (Bottom) FLSmidth’s stainless steel cages. world dictate that each cage is a custom design, tailored to the client’s specific requirements. All types, Service Cages, Auxiliary and Trailer Cages, each with many options and alternatives, such as various designs of cage floors, doors, roofs, removable intermediate decks, and removable counterweights are available. Cages are usually designed with significant amounts of aluminum to maximize payloads. However materials of construction can include mild steel, stainless steel, and strategically placed combinations of these materials, depending on the application and service conditions. Safety For cages operating with single rope drum hoists, we provide Safety Mechanisms for either wood, steel, or rope shaft guides. The safety mechanism, which is activated by a slack rope condition, brings the cage to a controlled safe stop. cages are also designed to operate with a multi-rope Koepe hoist. We also provide rope attachments and Safety equipment such as Arrestor Frames for the head frame and shaft sump. These devices are designed to create a predict- able deceleration and bring the conveyance to a stop in the event of a hoist problem. Suspension Traveling at high speeds, these large conveyances also require proper suspension. We offer several types of heavy-duty Guide Rollers and Suspension Systems to suit all conditions. Stainless steel cage Shown to the right (top) is a BMR cage with 112 man capacity. The cage shown to the right is stainless steel construction with an aluminum roller door on the bottom deck. The top deck is equipped with an aluminum guillo- tine door. The Aluminum Roller Door can be supplied with a spring or segmented counterweight. Design All cage designs are based on over 80 years of experience of supplying thousands of cages. With that documented experience, our methods and standards are coupled with the latest technology engineering design methods and Quality Assurance Systems to produce a Certified Safe and long-lasting cage. 10 Rebuild / Refurbish skips and cages FLSmidth rebuilds and refurbishes our own and other manufacturers’ Skips and Cages to a functionally new condition.

    Authority: 30 U.S.C. 811, 825(e). Source: 45 FR 47002, July 11, 1980, unless otherwise noted. § 49.1 Purpose and scope. This part implements the provisions of Section 115(e) of the Federal Mine Safety and Health Act of 1977. Every operator of an underground mine shall assure the availability of mine rescue capability for purposes of emergency rescue and recovery. § 49.2 Availability of mine rescue teams. (a) Except where alternative compliance is permitted for small and remote mines (§49.3) or those mines operating under special mining conditions (§49.4), every operator of an underground mine shall: (1) Establish at least two mine rescue teams which are available at all times when miners are underground; or (2) Enter into an arrangement for mine rescue services which assures that at least two mine rescue teams are available at all times when miners are underground. (b) Each mine rescue team shall consist of five members and one alternate, who are fully qualified, trained, and equipped for providing emergency mine rescue service. (c) To be considered for membership on a mine rescue team, each person must have been employed in an underground mine for a minimum of one year within the past five years. For the purpose of mine rescue work only, miners who are employed on the surface but work regularly underground shall meet the experience requirement. The underground experience requirement is waived for those miners on a mine rescue team on the effective date of this rule. (d) Each operator shall arrange, in advance, ground transportation for rescue teams and equipment to the mine or mines served.

    Freight Car Classifications Kerry Cochran 1/27/2021 The Association of American Railroads has 11 basic classifications of freight cars. Most of the major classes have subclasses. The National Model Railroad Association also offers reprints of the 1943 and 1953 ORIGINAL RAILWAY EQUIPMENT REGISTER (ORERs). An excellent article “Guide to Car Type Codes”, by Eric A. Neubauer, can be found at this link: https://eaneubauer.ipower.com/type.pdf Association of American Railroads' Plate designations Class "F" - FLAT CAR TYPE FA - Flat car specifically equipped with superstructure or containers for transporting set-up vehicles, not suitable for miscellaneous commodities. FB - Bulkhead flat cars. Equipped with fixed or permanently attached movable bulkheads or ends, a minimum of three feet in height and flat floor for general commodity loading. FBC - Flat car constructed with a center beam above the car deck from bulkhead to bulkhead. FC - Flat cars specifically equipped to carry trucks, trailers, containers, chassis, or removable trailer bodies for the transportation of freight in TOFC/COFC service. FCA - Flat car, articulated multi-unit, specially equipped to carry trailers, containers, chassis, or removable trailer bodies for the transportation of freight in TOFC/COFC service. FD - Depressed-center flat car of special construction having the portion of the floor extending between trucks depressed to provide necessary head room for certain commodities. FL - Flat logging car or logging truck. This is either a straight-deck flat car, with or without bulkheads or load restraining devices, or a car consisting of two trucks fitted with cross supports over truck bolsters; the trucks connected by a skeleton or flexible frame and logs loaded lengthwise on cross supports.

It is assumed that the reader has a general idea of mining practice. Compared with the broad old science of mining, the apphcation of the power-shovel is relatively new, and perhaps for that reason, information concerning its use is not so widely known. The majority of those in charge of such operations are practical men httle given to writing. Many have been drawn from in- dustrial and constructive engineering fields rather than from mining, and some are at times inclined to guard the details of successful methods which have been gained only after long experience.
