2-ton General Utility Vehicle, Type 2 (Karrier)

1. General
This Instruction describes the 2-ton General Utility Vehicle, Type 2 (Karrier). It is the standard vehicle for heavy general-purpose gangs of up to five men but, by using the occasional seating in the body of the vehicle (see par. 2), the facilities provided may be found suitable for gangs of up to seven men. General views of the vehicle are shown above.

Fig 3

2. Seating arrangements
In the over-engine cab, the driver and one passenger occupy forward positions. The driverís seat is adjustable in the forward or rearward direction. The locker situated on the off-side of the rear of the cab is upholstered to form a seat for two passengers. A seat which folds to facilitate access to the rear of the cab is situated near the rear cab door and accommodates a fifth man. Fig. 4 is an interior view of the cab. Within the body, a folding seat for occasional passengers is located on the near-side.

3. Writing facilities
A folding table with lamp above is provided. The under-seat locker and two wire-mesh compartments in the rear of the cab provide accommodation for books and papers.

4. First aid kits
A pair of straps are provided in the cab on the off-side, to hold the gangís first aid outfit. The driverís first aid outfit is placed high up on the off-side within the cab.

5. Modification to straps for gangís first aid outfit
On vehicles with serial numbers of U 80400 and below, it is possible that variations in the positioning of the straps in the cab, coupled with variations in the sizes of the first aid boxes No. 2 and constructional features in the cab, will cause difficulty in securing and handling the first aid box. Difficulty of this nature often results in the carriage of the gangís first aid box in odd corners of lockers, so defeating the express object of providing straps for securing the first aid box in a prominent and accessible position in the cab.

If such difficulty is encountered, a request should be made to the R.M.T.O. to arrange for the repositioning of the straps to suit the size of first aid box held.

After modification, or if the first aid box already held fits, care should be taken to avoid unnecessary requests for subsequent modifications to the straps. For example, the first aid outfit should be replenished under the terms of GENERAL, General, A 0551 and not replaced, unless the box is unserviceable or obsolete.

6. Cab temperature control and demisting
A measure of temperature control within the cab is provided by use of a baffle plate, situated behind the radiator grille. Insertion of this baffle allows heat from the engine to warm the cab. Conversely, removal of the baffle allows cold air to flow between the engine and cab floor to keep the cab cool. The baffle plate will be removed (or replaced) at commencement of the appropriate season of the year, by M.T. staff, and will be stored in the workshop during the warm season. Two slots at the base of the windscreen direct warm air (which rises from the cab floor when the baffle plate is fitted) to the windscreen for demisting purposes.

7. Use of wiring drums
To facilitate the paying out of wire from the vehicle, three spindles are provided as part of the vehicle equipment. The spindles fit into sockets in the floor of the body at the rear (see Fig. 5) and, when not in use, are accommodated in other sockets beside the rear off-side pole bolster support (see Fig. 7). Two spindles are designed to carry drums for 40-lb. wire and the third spindle will accommodate the wiring drum from a drum barrow for larger gauges of conductor. Wiring drums are not provided with the vehicle and requirements should be met from drums recovered from old Utility Vehicles and from surplus drums already available locally (e.g. from 1-ton Utility Vehicles used by jointers).

8. Ladder carrying facilities
A ladder rack is provided inside the vehicle on top of the off-side racking, with a door at front and rear to allow projection of longer ladders. Two devices each comprising a cleat, 8 ft. of sash line, a hooked plate and variable anchorage are employed to secure the ladder pile. They give an adequate range of adjustment for varying heights of ladder pile and are arranged to prevent their being trapped under the ladders when ladders are being placed on the rack. The sash line is held captive to the shelf framing to prevent its loss. The ladder pile must always be firmly secured before the vehicle moves off. Figs. 5 and 6 show a typical set of ladders in position.

To load a long ladder the weather screen should be furled. The trap door at the front of the ladder rack and the adjacent trap door(s) should be opened as necessary. The ladder securing devices should be pulled clear, the trap door at the rear of the ladder rack opened and the hinged section of the roll shutter guide lowered (see par. 11). The ladder is then passed through the main entrance into the body of the vehicle and the head of the ladder through the forward pole aperture until the ladder is so positioned that it can conveniently be lifted cleanly on to the ladder rack or ladder pile (Fig. 6). Similarly, a ladder should be lifted cleanly off the ladder rack or ladder pile before it is unloaded from the vehicle.

Ladders must not be propped up against the roof or side of the vehicle. Apart from damaging the vehicle, an accident may result particularly if the vehicle should be inadvertently moved.

9. Pole carrying facilities
A bolster system is provided for the carriage of poles. The front bolster is built into the vehicle framework while the rear bolster is removable and is stowed under the floor when not in use (see Fig. 3). Two pole guides are provided with the vehicle. These pass through guides in the rear pole bolster and fit into sockets in the floor of the body. To prevent the pole guides being dislodged, securing pins are provided and are held captive to the rear bolster bar by short lengths of chain. The securing pins fit into holes in the pole guides and bear against the underside of the rear bolster when in position. The pole guides when not in use are accommodated in sockets beside the off-side rear bolster support (see Fig. 7).

Fig 7
 
Fig 8

The forward end of the body is equipped with three trap doors to facilitate adjustment of the pole opening to suit the pole load. Opening and closing of the trap doors is effected from inside the vehicle with the aid of a simple hooked tool which is carried in clips above the pole opening (see Fig. 8). The hooked tool provided should always be used when lowering a trap door to avoid damage to the trap door and cab roof.

The pole heads are lashed to rings provided on the front bolster and the pole butts are lashed to the rear bolster. Full advantage should be taken of pole guides to prevent accidents due to poles twisting during loading and rolling uncontrolled across the bolster, and also to secure poles in a central position if required.

The arrangements provide for the carriage of poles of maximum length 36 ft. up to a total load of 30 cwt., care being taken to adjust other loading as necessary to avoid exceeding the total permissible vehicle load (par. 13). Card A 706 gives a guide in estimating pole weights for loading purposes.

10. Weather screen
A canvas weather screen (see Fig. 8) closes off the forward section of the ladder shelf and contains any rain entering to the ladder shelf, which is suitably drained. The weather screen can be rolled up, as shown in Fig. 6, to leave the ladder shelf clear for the handling of ladders.

11. Roll shutter
A light alloy roll shutter is provided at the rear of the vehicle (see Fig. 3). A section of the shutter guide is hinged and can be lowered to leave the ladder shelf clear for the easy manipulation of ladders. This hinged section should be lowered under control (see Fig. 6) to prevent damage to the hinge and minor accidents. A spring catch prevents the shutter being inadvertently pulled down with the hinged section of the guide lowered.

NO ONE MUST TRAVEL IN THE REAR OF THE VEHICLE WITH THE SHUTTER DOWN.

12. Loading aids
Two skid boards are issued with each vehicle and are stored beneath the floor (see Fig. 3). Each skid board is designed to withstand a maximum load of 15 cwt. A block anchorage (see Fig. 8), located on the forward racking, is provided so that a block and tackle may be used in conjunction with the skid boards for loading heavy items. Lashing eyes (see Fig. 5) are arranged down each side of the clear floor space to enable heavy items, particularly cable drums, to be securely chocked and lashed. When a cable drum is stowed close to the tailboard, the additional safety precaution of placing the rear bolster in position should always be taken to avoid damage to the roll shutter or tailboard in the event of the drum moving.

Loads should not be placed on the rear folding step even for temporary support during loading operations.

13. Maximum load
The maximum distributed load which may be carried is 2 tons, including driver, passengers, tools, etc., but floor strength considerations limit the maximum spot load (e.g. a drum of cable) to 1 ton.

14. Work bench
The top of the forward racking forms a convenient work bench on which a parallel vice may be mounted, using a packing block made locally.

15. Accommodation for tools and stores
Within the body racking, arranged along the off-side and front end of the body, are suitably partitioned compartments and drawers for the accommodation of tools and light stores (see Figs. 7 and 8). Four partitioned drawers are available for small stores. Saws and augers may be accommodated on hooks and clips on the rear wall of the centre-top off-side compartment, and the smaller tools are segregated by divisions in this compartment and in two drawers. The bottom off-side compartment is accessible from the outside of the vehicle by a trap door, at the rear, and is designed for stowing digging kit. A separate lockable compartment is provided to secure special items during casual absence from the vehicle, e.g. for the security of telephone instruments if a gang includes a fitter. Small-gauge wire, drop wire, etc. should be accommodated in the lower near-side compartment of the forward racking. Six loose partitions are provided, five being large partitions for general use and one small for use in the lockable compartment, at the discretion of the foreman. The two-tier insulator rack fitted in the off-side top-rear compartment is removable. Fig. 9 shows this insulator rack and specimen loose partitions.

Fig 9

The layout illustrated in this Instruction is only a typical one suitable for A.N. gangs. The fittings are, however, adaptable to the requirements of other duties but, owing to the wide range of duties on which the vehicle may be used, it is not possible to recommend any fixed layout. It is left to the discretion of the foreman to make the best use of the facilities provided.

16. Carriage of heavy-gauge wire
A retaining bar is provided inside the vehicle, on the near-side, for the convenient stowage of stay wire and heavy-gauge copper wire (see Fig. 5).

17. Coat hooks (see Fig. 5) are provided within the body, on the near-side.

18. Towing facilities
Provision is made for towing trailers with over-run brakes and which do not exceed a maximum gross weight of 45 cwt. The towing hitch is mounted on a spring-loaded draw-bar.

19. Special modification to improve towing capacity
A limited selection of 2-ton General Utility Vehicles nominated by Regions have been specially modified
as follows:-

  1. Vacuum trailer-braking equipment has been added.

  2. The towing hitch has been repositioned at a higher level to obtain a stronger mounting.

  3. The removable cabling bollard has been replaced by a fixed bollard.

  4. The rear pole bolster stowage position has been moved to above the spare wheel on the off-side.

This modification allows the modified vehicles to tow trailers equipped with vacuum braking up to a gross trailed load of 5 tons and, at the same time, maintains the original facilities for cabling and pole bolster stowage.

20. Future requests for special modification to increase towing capacity
A small stock of conversion kits is available to meet future requests for the modification to increase the towing capacity of a 2-ton General Utility Vehicle. When an Area Engr. is satisfied that such a modification is justified, a request (form MTE 26G) quoting the serial number of the vehicle, together with a statement of the circumstances justifying the modification, should be forwarded to the RD. (Eng. Bch.) for authority. Authorized requests should be forwarded to the R.M.T.O. for implementation.

21. Cabling facilities
An open-ended bollard is provided for pulling in cables by means of the vehicle. Mechanical Aids, C 1006 details the principles and precautions which apply to such a cabling operation. The bollard is attached to a spring-loaded draw-bar, via the towing hitch pin in its reversed position. Normally the bollard is left in place and need only be removed when it is necessary to tow a trailer (see also par. 19).

THE VEHICLE MUST NOT BE DRIVEN IN REVERSE TO PERFORM A CABLING OPERATION.

The hook (or anchorage) fitted on the front of the vehicle is provided for vehicle towing and maintenance purposes only.

22. Vehicle tools
The vehicle tools are accommodated, together with a trailer number plate and a vehicle handbook, in a separate tool box situated on the off-side of the vehicle. The jack handle is located in clips in the cab (see Fig. 4). A budget key is carried in a clip on the rear wall within the cab.

23. Mechanical tyre pump
A mechanical tyre pump outlet is situated below the near-side of the cab floor. The mechanical tyre pump is brought into operation by means of a separate gear lever, situated below the off-side of the cab floor, adjacent to the pump. Two men are necessary to engage the air pump, one to depress the clutch pedal with the engine running and the other to operate the pump-gear lever. The pump should be disengaged immediately after use by simply operating the pump-gear lever. The air hose supplied for use with the mechanical tyre pump is equipped with a double-headed type of connector to ensure easy access to all tyre valves.

24. Locking arrangements
The rear trap door for gaining access to digging tools is equipped with a budget lock and an inside catch. All ladder and pole trap doors are fitted with bolts on the inside. The foremanís paper locker, vehicle tool locker, security compartment and the rear shutter are secured by means of padlocks. Padlocks are not supplied with the vehicle and sufficient Padlocks with Keys, 2 in. with 2 keys of the same suite should be requisitioned when a new vehicle is received. Care should be taken to maintain all padlocks on any one vehicle in the same suite, if replacement locks are requisitioned. Cab doors are equipped with standard barrel locks (FA 600).

25. Garaging
The overall dimensions of the 2-ton General Utility Vehicle, Type 2 (Karrier) are:-
Length 20 ft.
Width 7 ft. 5 in.
Height 9 ft. 7 in.

Ladders carried in the vehicle will, of course, increase the overall length and garaging space should be assessed accordingly. If several vehicles are to be garaged, space should be allowed for gangways, cleaning, etc.

26. Speed limit
Because of tyre-loading limitations, the maximum speed is limited to 20 m.p.h.
