DESIGN REQUIREMENTS Design, systems, hardware, and material used in the manufacture of the conveyor must meet automotive stand
15、ards and good industry practices. The loader shall be designed for easy access to those areas that require frequent checks for servicing.3.1 Physical Characteristics 3.1.1 Overall dimensions of the aircraft cargo conveyor shall be within 347 in (8.81 m) long and 88 in (2.03 m) wide. The vehicle shal
16、l have a minimum front to rear wheelbase of 110 in (2.8 m). Overall height should be kept as low as possible consistent with good operation, safety, and ground clearance. 3.1.2 The loader must be capable of servicing all commercial aircraft cargo compartments. This requires a range of travel of the
17、forward end of the conveyor of a minimum of 38 in (0.97 m), from the ground in the conveyor full down position, to a minimum of 170 in (3.8 m) in the full up position. The rear end of the conveyor must maintain 20 in (0.51 m) to 24 in (0.58 m) through the entire height range of the forward end and e
18、xtend to a minimum height of 50 in (1.27 m). 3.1.3 The turning radius as measured from the outside corner of the vehicle shall not be greater than 25 ft (7.6 m). 3.1.4 The following characteristics shall be met under normal operating conditions and loads: a. Approach angle: 16 degrees (0.28 rad) min
19、imum b. Ramp breakover angle: 10 degrees (0.18 rad) minimum c. Departure angle: 10 degrees (0.18 rad) minimum 3.1.5 The conveying belt shall be 24 in (0.61 m) wide. Usable conveyor bed width shall be a minimum of 30 in (0.81 m) with guides and a maximum of 40 in (1.02 m) overall. 3.1.6 The belt conv
20、eyor shall have tire tread suitable for outdoor use and all performance requirements as specified in this document. 3.1.7 The minimum ground clearance shall be at least 5 in (0.13 m).

21、ted without license from IHS-,-,-SAE ARP1836B - 3 -3.1.8 The loader chassis shall have rub rails on both sides for protection against damage. 3.1.9 To minimize aircraft damage the forward end of the conveyor support structure shall be protected with a type of rubber bumper. 3.1.9.1 First Bumper Alte
22、rnative Bumper does not extend across the front of the conveyor bed, but is mounted to the support structure on either side of the conveyor bed, reducing finger pinching hazard. 3.1.9.2 Second Bumper Alternative Bumper is full width, 5 in (0.13 m) ID x 7 in (0.18 m) OD (minimums). CAUTION: The gap w
23、idth between the bumper support and belt at the front of the conveyor should be chosen with great care. If too small, the risk of getting fingers caught exists. If too large, packages can get stuck or fall through the gap. 3.1.10 The operators control area shall have adequate room to safely and effi
24、ciently operate the loader. Recommended dimensions to accomplish this are shown in Figure 1 and Table 1.

31、t shall not require more than 20 lb-ft (27.1 n-m) torque as measured from the circumference of the steering wheel. 3.2.3 Service brakes shall be of a dual system hydraulic design with split master cylinder and indicator light on dash to warn the operator if one system fails. Drum brakes, disc brakes
32、, or combinations of both are acceptable. The maximum permissible stopping distance from full speed on level ground shall not be greater than 25 ft (7.6 m). A brake pedal force required to meet this distance shall not be more than 100 lb (444 n). 3.2.4 The suspension system shall be adequate to prev
33、ent chassis bottoming under normal operating condition with a full rated load. 3.2.5 Drive wheels shall have at least 2.0 in (5.1 cm) of clearance to permit installation of tire chains. 3.2.6 The operators seat shall be adjustable fore and aft with a minimum range of 6 in (0.15 m). See Figure 1. 3.2
34、.7 The loader shall be equipped with an adjustable overcenter manual type hand brake with a pulling motion toward the operator engaging the brake. 3.2.8 The directional control switch for traction drive shall have three positions: a. Forward b. Neutral c. Reverse The reverse position shall be to the
35、 front, neutral in the middle, and forward to the rear. NOTE: For international operators, these positions may have to be reversed. The neutral position must have a detent. Operation shall be for a right-handed person. 3.2.9 Provisions for adjusting belt tension and alignment shall be made. 3.3 Elec
36、trical System 3.3.1 The cargo conveyor is to operate on a common industrial battery pack powering the vehicle, conveyor lift, and belt drive. The preferred method for electric drive utilizes an electronic controller capable of producing smooth acceleration and operation. Battery voltage shall reflec

Battery cleanliness to prevent ac
38、id leakage paths is of utmost importance and every attempt to facilitate same should be taken into consideration in the design. 3.3.3 A separate 12 V DC accessory system using chassis ground to accommodate standard automotive equipment shall be provided. The preferred method to provide the 12 V syst
39、em is through an electronic DC to DC converter with or without a cycling type 12 V storage battery.

44、rformance requirements apply to the loader on dry, level concrete of good quality and an outdoor ambient temperature range of 5 F (-15 C) to +95 F (35 C), unless otherwise specified. Note that this is not the operating temperature range of the equipment, which is as specified in ARP1247. 4.1 The max
45、imum speed of the vehicle with no load shall be approximately 15 mph (24.1 km/h). 4.2 Total distributed load capacity of at least 2000 lb (907 kg) for conveyor angles up to 15 degrees (0.26 rad), and at least 1000 lb (453.6 kg) at the maximum conveyor angle of the loader, is required. 4.3 The convey
46、or shall have a load density rating of at least 200 lb/ft2(976.4 kg/m2).4.4 Conveyor belt speed shall be manually or electronically controllable within a range of 40 to 100 ft/min (12.2 to 30.5 m/min) with any loads up to those specified in the duty cycle requirement (see 4.7). 4.5 The belt drive sy
47、stem shall not permit a load to move more than 0 in/min in the unpowered (belt motor off) state. This condition applies to any loads up to those specified in 4.2 and 4.3 and in any weather conditions. 4.6 Conveyor lift speed with no load shall be at least 25 ft/min (7.62 m/min). Conveyor lowering sp
48、eed at no load shall be within 50% of lift speed; i.e., within a range of 12.5 to 37.5 ft/min (3.81 to 11.43 m/min). 4.7 As a minimum requirement, the battery pack and electrical system shall be designed to meet a duty cycle of 1.5 h actual vehicle travel time and 4.5 h of conveyor belt operating time before recharging or changing batteries. For purposes of testing and specification, the following conditions shall be used: a. Vehicle Operation: 1. Vehicle traveling with no load (except operator) at various speeds 2. 15 full stops and starts Copyr
