Interesting Facts and Figures Dealing with the Operation of Two Karrier Vans which have seen Considerable Service.
T HE transport records of those users who have employed motor vehicles for many years are usually most instructive to other owners or prospective owners, and particularly to those engaged in Similar lines of business: The information to he gained from a study of the figures contained in such records enables other owners to ascertain whether they are securing the best results from their machines, whilst it also provides potential users with certain interesting data which serve BS a useful working basis if they are not possessed of a knowledge of the intimate details surrounding the operation of motor vehicles.
It is for this reason that we feel that the experience of Wyman and Sons, Ltd., the printers and publishers, will be perused With Interest by many of our
readers. The facts which are incorporated in thefollowing brief article have been communicated by Mr. A. V. Nicholls, of that company, to Karriers Motors, Ltd., of Huddersfield.
We reproduce on this page two illustrations of the Karrjer vehicles in the service of Messrs. Wyman. One of them was delivered over ten years ago, whilst the other, which is a Peeent• repeat order and is a present-day prpduction, enables an interesting comparison to be made showing the remarkable advances which have been made in general design.
Chassis No. 344, which is a 2-tonner which was turned out of the Karrier works in October, 1912, was delivered to Messrs. Wyman on the 30th of that month, and has since been in use night and day, covering, as a rule, 45 miles each working night and 35 miles each working day. It has been in service for six days a week, and thus covers a weekly mileage of approximately 450.
During the period of ten years over which this van has been in service, it The total cost of running repairs, including overhauls and replacements, which have been carried out on . this vehicle, has amounted during the entire period to £227 13s. 4d., which, when one considers that the total mileage credited to the vehicle since it was put into commission amounts lo 227,250, is reflective of most economical and efficient running.
The second Karrier vehicle to be put into service by Messrs. Wyman was Chassis No. 353, of 30-cwt. capacity, which Was delivered on January .10th, 1913. This • vehicle has run approximately, 60 miles per night and 24 miles per day since it was first put into service, and has thua accomplished an approximate mileage of 504 for each working week of six days.
This vehicle has been off the roach for 12 weeks in nine years-for repairs and overhauls, the total cost of which, including replacements, has been £100. The petrol consumption during the period has been one gallon for 15 miles' running, and an equivalent quantity of oil has been consumed in each 400 miles of running. This particular machine has covered a mileage slightly in excess of its heavier companion, the exact figure being 229,824.
From first to last the two machines have usually carried their maximum loads, and we think that herein very largely lies the reason for the continuous successful running of the vans.
As a result of the complete satisfaction given by these two vans, Messrs. Wyman plated an order for a OX-type Karrier box van, which was delivered by the manufacturers on September 28th last year, and with which they express themselves completely satisfied, No actual running details are, of course, yet available for this machine, and they would not serve any direct purpose. The first two vehicles purchased by the company have such a 'lengthy term of service to their credit that it is worth analysing the figures in order to arrive at the rate of depreciation and other items.
• The original cost of Chassis No. 344 was £558, and of Chassis No. 353 £472. If we assume that each vehicle has now _completed its useful life, we should have, in the Case of No. 353, a first cost of 113,280d., and a mileage of 229,824, which enables us to arrive at a rate of depreciation which is little under id. a mile. In point of fact, the vehicle is still doing useful work, from which it is apparent that an allowance of d. per mile for depreciation is more than adequate.
Chassis No. 344 is also still doing useful work, and before long will, no doubt, have Covered a mileage which would justify an equally low estimate for depreciation.
So far as repairs are concerned (an item which includes overhauls and replacement), it will be seen that, in the ease of the 30-cwt. vehicle, on a repair bill of 24,000d. and a mileage of 229,824, the charge under this heading has been something less than -id. per mile. The repairs in the case of the 2-tonner work out at approximately *d. per mile.
We think our readers will agree that., bearing in mind the common practice of allowing something in the neighbourhood of 111 per mile for depreciation on vehicles of the capacity referred to, and of not less than id. per mile for repairs and overhauls, the results obtained by Messrs. Wyman from their vans have proved striking testimony to the reliability and durability of Karrier products, which were manufactured at a period when such features were not always associated with the design of commercial motor vehicles. Moreover, the fact that Messrs. Wyman have purchased a third van from the Huddersfield company is an indication that Karriers Motors, Ltd., have kept abreast of the general advance in design and construction of industrial vehicles.
