The design f an M-series trailer varies depending n the vehicle type. Refer t the manufacturer s peratr s manual fr additinal infrmatin n the specific M-series trailer being perated, and t the data plate fr safe lad capacity guidance. The M-series trailer nrmally can be identified by the fllwing characteristics: All trailers are designed t be twed by a twing vehicle withut airbrake cnnectins. A handbrake lever and cable assembly lcated n each side f the trailer activates a handbrake at each wheel. Cntrl f each handbrake is independent In sme cases, in additin t handbrake lever-activated handbrakes, the trailers are equipped with an inertia-actuated hydraulic brake system Flatbed trailers design. See Figure Used t carry munted systems ver highways and crss-cuntry All trailers have an air/hydraulic brake system which receives air pressure frm the twing vehicle thrugh inter-vehicular air hses Leveling jacks n the fur crners f the trailers prvide stability during lading and ff-lading.

8 Figure 5.1. Flatbed Trailer Design Chassis trailer design. See Figure The chassis trailer design is an pen-frame, single-axle, super single r dual wheel cnfiguratin trailer chassis. The chassis trailer is primarily used t transprt electric generatrs. It can be used n imprved and unimprved rads, and can be used with the Mine Clearing Line Charge (MICLIC). Figure 5.2. Chassis Trailer Design Cmmn features Electrical system. Receives its pwer frm the twing vehicle thrugh the trailer intervehicular cable assembly. Prvides pwer t the antilck brake system (ABS) and taillights lcated at the rear f the trailer.

9 Brake system. Nte: Later mdels are equipped with ABS The ABS is a self-mnitring electrnic system that wrks with the trailer's air/hydraulic brakes. When pwered by the twing vehicle, the ABS will cnstantly mnitr trailer wheel speed and cntrl trailer brake functin during wheel lck situatins. This system imprves vehicle stability and cntrl by reducing trailer wheel lck during braking. See Figure 5.3. Figure 5.3. Antilck Brake System.

Extend frm the air filters t supply service and emergency air t the emergency relay valve, air reservir and air brake chamber. Cntrls the braking system f the trailer. Based n the air pressure signals received frm the twing vehicle, it will apply r release the service brakes r it will initiate an emergency brake applicatin. The air reservir stres the system air pressure minimum that perates the brake system. Pressure t the reservir is initially supplied and then maintained thrugh the emergency supply line frm the twing vehicle thrugh the emergency valve. The air brake chamber cnverts air pressure t mechanical mtin. This mvement thrugh the hydraulic master cylinder applies the brakes. When air pressure in the air brake chamber is released, spring actin releases the brakes. The hydraulic master cylinder cnverts the mechanical mtin f the air brake chamber t hydraulic pressure which travels thrugh the hydraulic lines t the wheel cylinders. The wheel cylinders cnvert system hydraulic pressure t mechanical mtin and frce the brake lining against the brake drum. Cause frictin t slw r stp the trailer.

The fllwing guidance pertains t perating all M-series trailers (with twing vehicle). Later in the sectin, additinal guidance pertaining t the flatbed M- series trailer, chassis M-series trailer, carg M-series trailer and water tank M-series trailer is prvided. This guidance is nt all-inclusive. Trainer and trainee shuld refer t the manufacturer s peratr s manual, Pintle Hk Lessn Plan, Hazardus Material Lessn Plan and AFMAN fr cmprehensive guidance applicable t the specific M-series trailer type/mdel being used Twing prcedures When trailer is cupled, always start and stp twing vehicle slwly and gradually. D this whether r nt trailer is laded Sudden and fast acceleratin will cause hydraulic brakes t apply.

28 When driving twing vehicle and trailer, verall length f unit must be kept in mind when turning and passing ther vehicles. Because unit is hinged in the middle, turning and backing are als affected. Heavier paylads will increase stpping distance and decrease ff-rad maneuverability Turning When turning crners, allw fr the fact that the trailer wheels turn inside the turning radius f the twing vehicle T make a right turn at an intersectin, drive twing vehicle partway int the intersectin, then cut sharply t the right. This will allw fr the turning radius f trailer, and keep trailer wheels ff the curb Backing Always back the twing vehicle slwly and gradually Always use a sptter. The peratr must maintain visual cntact with the sptter at all times. If visual cntact is lst, the peratr will immediately stp the vehicle. See AFMAN fr additinal guidance n standard AF sptter hand signals and additinal sptter safety guidance Adjust all twing vehicle rearview mirrrs befre backing, as needed When backing, rear f trailer will mve in ppsite directin in which twing vehicle is turned. When twing vehicle is turned t the right, rear f trailer will g left. When twing vehicle has turned and backing in a straight line is required, turn the twing vehicle in directin trailer is mving. This will slwly bring twing vehicle and trailer int a straight line Stpping Always stp twing vehicle by applying brakes gradually and smthly.
