CYCLE TIME SEGMENTS AND CYCLE TIME DISTRIBUTION CURVES OF MINING SIZE WHEEL LOADERS - A CASE STUDY

Abstract

Mining wheel loaders loading haul trucks, in contrary to earthmoving equipment which have 360
degrees slewing capability of upperframe, have an entirely different cycle time phases: Travel
to dig (TTDG), Dig (DG), Travel to dump (TTDMP), and Dump (DMP). Therefore, the cycle time
(CT) of a mining loader is comparatively higher than that of an equivalent sized excavator with a
rotating upper frame. However, whenever mobility and versatility of the loading tool is essential
such as selective mining applications the wheel loaders are favoured. Investigating cycle time
segments may give qualitative and quantitative hints for improving the cycle times of the loader
applications upon changing the operators and the truck spotting layouts. Therefore, studying
cycle time statistics and cycle time frequency distribution curves are important. In the article, two
cases are explored one being from Brasil, the other one is from Turkey. Sample CT segments and
CT distribution curves are investigated and discussed

Keywords

Electrical wheel loader, cycle time segments, cycle time distribution curves, normal distribution curve, skewed distribution curve

Abstract

Kazdıklarını kamyona yüklemekte olan tekerlekli maden yükleyicilerinin döngü süresi evreleri
kule dönüşlü makinalardan bütünüyle farklıdır. Bu evreler kazıya gidiş, kazı, boşaltmaya gidiş
ve boşaltma evrelerinden oluşur. Bu nedenle maden yükleyicisinin iş döngüsü eşdeğer kule
dönüşlü yerkazardan daha uzundur. Ancak seçmeli kazı gerektiren madenlerde olduğu gibi çok
gezingenlik ve esneklik gereken uygulamalarda yükleyiciler yeğlenir. İş döngüsü evrelerinimn
incelenmesi iş döngüsünü geliştirme yönünde nesnel ve nicel ipuçları verebilir. Özellikle operatör
değişikliklerinde ve kamyon yanaştırma düzeni değiştirildiğinde, bu evreler incelenmelidir. Bu
yüzden iş döngüsü istatistiklerini ve iş döngüsü dağılım eğrilerini incelemek olağanüstü önemlidir.
Bu makalede biri Brezilya’dan biri de Türkiye’den olmak üzere iki olay çalışılmıştır. Örnek iş
döngüsü evreleri ve iş döngüsü dağılım eğrileri araştırılmış ve tartışılmıştır
