AJHR Totals

This page presents data on cranes in railway service as listed in the annual reports tabled in Parliament and recorded in the Appendicies to the Journal of the House of Representatives (AJHR).

The Railway Statements in the AJHR from 1881 to 1915 present a wide range of detail on the operation of the working railways. Amongst the summaries of locomotives and rolling stock up to that time are a breakdown of the numbers of cranes of various types in service on the various railways sections. These give an interesting picture of the development of equipment stocks during this period. Unfortunately much of this was discontinued during World War I as it was thought the information might be of service to 'the enemy'. Equally unfortunately, it was not included again after the war ended. But what information there is in the AJHR can be very useful.

Presented below are:


Analysis of Crane Totals by year: The following graphs examine the data as grouped under a number of classifications for the data in the table below. This is a preliminary examination of the data, and some suggestions for areas which need to be looked at more closely!

Graph ofThe AJHR data provides an interesting picture of what was happening with the crane stocks in terms of increases and decreases. But to understand that picture is is necessary to understand the historic context in which the changes were occuring. The working railways arose from the public works projects started by Vogel in 1870. They became a seperate entity in 1880 which is when the data becomes more accessible. The early railway growth suffered as the financial situation turned to economic depression from the early 1880's - a situation which did not improve till the second half of the 1890s. Although the total stock still shows growth initially, it is necessary to consider how that tapered off, what was old orders arriving, and what happened in terms of new purchases and replacement of the stocks. Much of the growth from 1895 on (as seen in the graph at left) is in stationary cranes, presumably equipping the increasing number of stations being built at that time. From the end of the 1880s there is a slow growing collection of pile drivers and hoisting engines indicating an increasing mechanisation. From the early 1900s the records show an increasing use of overhead travelling cranes - perhaps reflecting the development of the workshop facilities.

Graph of Looking at the data for the stock of travelling cranes alone (considering only rail cranes and not including travelling overhead cranes) we see a mix of similarities and differences to the pattern for the total crane stock. Growth in stocks is limited up to the end of the 1880s when a sharp increase warrants further investiagtion. The crane numbers drop slightly to the mid-1890s when renewed growth accompanies the end of the economic depression. Renewed growth ends around 1910. The travelling crane stocks are static in the years that follow. General manager Mr E.H. Hiley 1914 proposal for an 8-year rejuvenation of the New Zealand Government Railways.was halted by the outbreak of war toward the end of the period represented. It would be of interest to get a better picture of the crane stocks in the years that follow.

A further area of examination should be the seperation of wharf cranes from the stock of breakdown/maintenance of way cranes. The larger capacity cranes can be identified as wharf cranes, but this is not yet possible with some of the smaller varieties.

Graph of Looking more closely at the travelling crane stocks, it is interesting to compare the hand and steam powered cranes. Steam power was utilised from very early on (the working railways inheriting steam cranes from the earlier Canterbury Provincial Railways and the Port Chalmers Railway). But it would seem that initially the hand powered cranes were more numerous. From the end of the 1880s when the stock received a large (and so far unexplained) increase the respective stocks were similar numerically to around 1904. From this point the number of handcranes appears to be in decline. It would appear the 1900-1904 period requires a closer examination as there is strong growth in powered cranes in the following few years. This ends in the immediate pre-war period and as noted above, it would be of interest to get a better picture of the crane stocks in the years that follow.
