This vehicle is designed for two-man parties employed on box building. The vehicle should be equipped with a 110v generator and electrically operated mechanical aids, i.e. a road breaker, a submersible pump, a cement mixer and a drill. Immediately behind the two-man cab is a lockable compartment to give security to mechanical aids, tools, protective clothing, etc. There is a water tank with a capacity of approximately 27 gallons so that clean water is available for cement and concrete mixing. A hydraulic HIAB crane of 1 ton capacity is fitted between the forward compartment and the rear platform. This crane will lift loads in the range 9 cwt. at 11 ft. 6 in. radius (using the outer hook and the manual extension on the boom.) to 1 ton at 5 ft. radius. Loads in excess of 15 cwt. must be lifted on the inner hook. The removable rear corner posts and drop sides facilitate loading and unloading operations. The load should be placed as far forward on the platform as possible and must not exceed 2 tons; loads exceeding this should be removed in more than one journey.
External under slung lockers provide storage for propane cylinders, paraffin containers and road lamps, etc. An air-tight locker built into the off-side of the forward compartment is for the storage of bags of cement.

Box Builder's Vehicle
Until recently, Areas were equipped with rather inadequate vehicles for Box Building parties. These vehicles were not purpose-built and offered poor accommodation for sand, ballast and tools. A vehicle has been designed to remove these failings, to take advantage of the power tools now available and provide better crew accommodation, which should lead to more efficient operations on jointing chamber construction and maintenance.
The vehicle has a two seat cab, behind which is an enclosed compartment for tools and mechanical aids, and has a translucent roof to give maximum light. All the large tools provided are electrically driven, the power being supplied by a propane driven 110V generator. Propane fuel is not so inflammable as petrol so that the generator can be run in this enclosed compartment by using an exhaust extension. The major tools in the vehicle kit are a road breaker, hammer drill, water pump, concrete mixer (carried on rear platform) concrete vibrator, flood lamps, together with all necessary hand tools.
Below the enclosed tool compartment on both sides of the vehicle are compartments to accommodate other items, such as red lamps, paraffin cans, propane cylinders, cones reflecting and bags of cement. Clean water is an essential requirement for cement mixing and a 30 gallon tank is provided at the rear of the tool compartment.
The rear platform - which has drop sides for easy access - carries storage bins for sand and ballast, skips for the carriage and disposal of spoil, cement mixer, frames and covers, shuttering, etc.
For handling heavy items such as frames and covers of approximately 5.5 cwt., skips full of spoil approximately 10 cwt., an hydraulic powered crane is provided. This has a three section folding jib of one ton maximum load, and can be controlled from both sides of the vehicle. Stabilising jacks are provided either side of the crane mounting to steady the vehicle when the crane is in use.
The colour of the vehicle is Traffic Yellow. This is a safety measure, as in course of its work, the vehicle spends much of its time parked at the roadside, or in the carriageway and in dull weather or against dark backgrounds, the bright colour makes the vehicle as conspicuous as possible to other road users.
The new Box Building vehicle offers great advances in tool, material, and crew accommodation over the stores carrying vehicle previously used for these jobs. This together with the mechanical aid facilities should lead to more efficient operation of Box Building parties. Some 180 of these vehicles are being obtained most of which have by now been delivered to Telephone Areas.
