It is generally thought that the first hydraulic mini-excavator was built by the Kobe Steel Co. in 1968 and was called the 10A model. They were followed by Takeuchi in 1971 and Kubota in 1974. These machines started to enter the UK in the 1980s and quickly gained popularity in the 1990s, until nearly every hire shop and builder now owns this type of compact machine. British manufacturers such as Smalley and Powerfab entered the market in the 1980s, but now nearly all machine designs originate from the Far East. Due to their reliability and low running costs, machines are rarely scrapped, they are resold as the years go by. 1980, and early 1990s models are now mainly in the ownership of small builders, landscapers, or even people completing self-build houses. There are at least 30 different brands of mini-excavator on the world market, although a great deal of badge engineering goes on, with modifications as necessary to suit the local market place. Japan has been the main market place for mini excavators, with Europe as the second major market. Due to the popularity of the skid-steer loader, mini-excavators have been slow to gain market share in the USA but in the last five years the number of sales have rapidly increased particularly in the cities. The recession in Japan has depressed the market there leading to many almost new machines being imported into the UK and other EU countries. These machines have been labelled grey market machines and have to be CE certificated by the importer. The machines coming from Japan can be models which are a number of years ahead of the current European machines, i.e. zero tail-swing machines have been sold in Japan for a number of years before they were available in Europe. Mini excavators are continually being developed and the technological advances can be summarised as follows. Interchangeable rubber tracks - early 1990s Servo controls, knuckle booms, extending dippers, - mid 1990s Zero-tail swing machines, half pitch rubber tracks late 1990s Asymmetric rubber tracks - by Yanmar early 2000s Offset Boom facility - - 2000s by Takeuchi and Neuson

T here are a num ber of types of rubber track w hich are listed below : C onventional rubber tracks T hese w ere the o riginal style of rubber tracks w hich w ere used on the earlier m odel m ini-excavators. T hey have p itches of 60m m , 72m m , and 100m m and are still used today on som e sm aller m odels of m achines. W ith th is type of track , if you needed to change from rubber tracks to steel tracks or v ice-versa, you have to change all the running gear on the excavator.
Interch an geab le ru b b er track s T his type of track w as m anufactured to overcom e the problem of changing from steel to rubber tracks w ithout having to change all the running gear on the excavator. T hey have p itches of 96m m , 109m m , 142m m , 144m m , 146m m , and 163m m . This track is fitted to excavators of up to approx im ately 8 tonnes.
H alf pitch in terchangeab le rubber tracks T hese tracks w ere designed to run on every tooth of the drive sprocket and so give a sm oother ride for the m achine and operator as opposed to the norm al p itch in terchangeable tracks. T hey are available in p itches of 48m m , 52.5m m , 54m m , 55m m , 71m m , 72.5m m , 73m m , and 81m m . W here there is only 0 .5 or 1m m difference betw een the p itches it generally sign ifies pitches used b y different track m anufacturers.

Komatsu and Yanmar type rubber tracks These tracks are a type where the bottom rollers run on the outside of the drive lugs as shown in the diagram paragraph 3 Chapter 2 about earlier rollers. They differ from all the other tracks because the steel insert has been made far stronger to support the weight of the machine on the outside of the drive lugs. The sprocket and the idler are of the conventional type and drive and support the track as on interchangeable tracks. The yare made in 101mm, 106mm, 107mm, 108mm, 142mm, 144mm, and 163mm pitches.
Asymmetric rubber tracks These tracks do not have the drive lugs in the centre of the width across the track (hence the name). They are offset for instance 25mm on a 300mm wide track, and then fitted to the excavator with the widest part of the track innermost. This narrows the track width across the machine by 50mm and when fitted to zero tail swing excavators, enables the machine to track through narrower openings, whilst still having the same ground pressure.
Other rubber tracks There are many other types of rubber tracks in use besides the tracks fitted to excavators. Some of these need different properties to allow reliable use such as more flexibility, different load bearing characteristics, non marking tracks etc. These tracks are used on many different types of machine for example snowmobiles, tracked dumpers, lifting platforms, agricultural tractors, military vehicles, skid-steer loaders plu
