INCH-POUND A-A-59914A 24 July 2013 SUPERSEDING A-A-59914 18 April 2013 COMMERCIAL ITEM DESCRIPTION DEMOUNTER, PNEUMATIC TIRE, BEAD BREAKER The G
3、eneral Services Administration has authorized the use of this Commercial Item Description as a replacement for PD03WR/LEEE Rev A, which replaced MIL-B-87986 and A-A-58053, for all federal agencies. 1. SCOPE. This commercial item description (CID) defines the requirements of a demounter, pneumatic ti
4、re, bead breaker rated at 25,000 lbs. The demounter, pneumatic tire, bead breaker is hydraulically actuated and powered by an air driven hydraulic pump (Type 1) or by an explosion proof electric motor (Type 2). The bead breaker is designed to break the bead of an aircraft tire (15 to 60 inches in di
5、ameter and 12 to 26 inches wide) from the rim of an aircraft wheel (13 to 32 inches in diameter). 2. CLASSIFICATION. The demounters, pneumatic tire, bead breaker defined by this document are of the following two types. Type 1 air driven hydraulic pump Type 2 explosion proof electric motor 3. SALIENT
6、 CHARACTERISTICS. 3.1 Functional requirements. The demounter, pneumatic tire, bead breaker shall provide a means of breaking the beads of tires from split wheel aircraft rims using a spider plate assembly with attaching segments or a universal spider adapter. It shall be capable of being operated by
7、 one person. The unit shall break both beads of the tire with one actuation (stroke) without damage to either tire or wheel. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59914A 2 The unit shall be provided with controls that allow in and out m
8、otion of the bead breaker cylinder as well as up and down positioning of the elevating cylinder. An instructional panel shall be affixed to the bead breaker. Instructions shall be clear, concise, and sufficient to enable operation of the machine without damage or injury to the operator. The panel sh
9、all be readily visible from the operators position. The demounter, pneumatic tire, bead breaker shall be finished to protect against corrosion normally found in a shop/hanger environment. The shipping weight shall not exceed 2,000 pounds. 3.2 Hydraulic system. The demounter, pneumatic tire, bead bre
10、aker, type 1 shall be provided with a hydraulic pump, control valve assembly, a relief valve and a hydraulic fluid reservoir. The air motor shall be capable of driving the pump and shall be equipped with an automatic safety relief valve to bypass hydraulic fluid from the pumps back to the reservoir.
11、 Demounters, pneumatic tire, bead breaker, type 2 shall be provided with a hydraulic system consisting of an electrically powered pump and all components and fittings necessary for safe, reliable operation. Both types of units shall be compatible with fluid conforming to MIL-PRF- 5606. All controls
12、shall be permanently marked as to operation and shall be capable of being operated by a person wearing heavy gloves. Action of controls shall be smooth and non erratic. 3.3 Electrical requirements (Type 2). Electrical equipment and wiring provided shall conform to the National Electrical Code, NFPA
13、70. Demounters, pneumatic tire, bead breaker, type 2 shall be provided with an explosion proof electric motor conforming to Underwriters Laboratories Class I, Group D, designed for connection to 220/440 volts, 3phase, 60 Hertz electrical power unless otherwise specified in the contract or purchase o
14、rder. 3.4 Spider plate assembly and universal adapter. Type 1 and type 2 demounters, pneumatic tire, bead breaker shall be provided with a spider plate assembly on both cylinders that allow for adjustable spades (fingers or segments) on each side. A universal spider adapter that incorporates these c
15、omponents can also be provided in lieu of the spider adapter and spade attachments. A minimum of four (4) spades or fingers shall be provided for each cylinder. 3.5 Safety. 3.5.1 Component protection. All space in which work is performed during operation, service, and maintenance shall be free of ha
16、zardous protrusions, sharp edges, or other features which may cause injury to personnel. All rotating and reciprocating parts and all parts subject to high operational temperatures or subject to being electrically energized, that are of such nature or so located as to be hazardous to personnel, shal
17、l be guarded or insulated to eliminate the hazard. All wires, cables, tubes, and hoses shall be supported and protected to minimize chafing and abrasion and shall be located so as to provide adequate clearance from moving parts and high operational temperatures. Grommets shall be provided wherever w
18、ires, cables, tubes, or hoses pass through bulkheads, partitions, or structural members. 3.5.2 Foreign object damage (FOD). All loose metal parts, such as pins or connector covers, shall be securely attached to the bead breaker with wire ropes or chains. “Dog tag“ style beaded Provided by IHSNot for
19、 ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59914A 3 chains shall not be provided. Removable panels, if provided, shall be attached with captive fasteners. Tire valve stem caps shall be made of plastic. 4. REGULATORY REQUIREMENTS. 4.1 Recycled recovered materials.
20、 Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. The offeror/contractor is encouraged to use r
21、ecovered materials to the maximum extent practicable, in accordance with 23.403 of the Federal Acquisition Regulation (FAR). However, used, rebuilt, or refurbished items shall not be provided. 4.2 Green Procurement Program. Green Procurement Program (GPP) is a mandatory federal acquisition program t
22、hat focuses on the purchase and use of environmentally preferable products and services. GPP requirements apply to all acquisitions using appropriated funds, including services and new requirements. FAR 23.404(b) applies and states the GPP requires 100% of EPA designated product purchase that are in
23、cluded in the Comprehensive Procurement Guidelines list that contains recovered materials, unless the item cannot be acquired: a) competitively within a reasonable timeframe; b) meet appropriate performance standards, or c) at a reasonable price. The prime contractor is responsible for ensuring that
24、 all subcontractors comply with this requirement. 5. PRODUCT CONFORMANCE PROVISIONS. 5.1 Contractor certification.
