Previous research has shown that the collection and analysis of crane operators' anthropometric characteristics is very important for operators' comfort, health and working ability and also from the aspect of performance, productivity and safety.
The first aim of this survey is to collect up-to-date anthropometric data of crane operators in Serbia and to collect those data for the first time in Libya. The second aim of this survey is to compare the collected data. The third aim is to model the interior space necessary to accommodate operators in the cabins they operate in Serbia and Libya.
Standing height, sitting height, lower leg length, upper leg length, shoulder width, hip breadth, arm length, foot length and weight data were collected of 83 Serbian and 50 Libyan crane operators. Descriptive statistics, correlation analysis and tests for differences between variables were conducted to examine differences between Serbian and Libyan crane operators and enable further modeling. The modeling of the cabin interior was done using both univariate and multivariate operators' models from both samples.
There are only four common correlations between variables for both samples. The only measurement without statistical differences is shoulder width. Serbian crane operators have statistically higher values of almost all measurements in comparison to Libyans. The minimal cabin interior space dimensions are 1207×1080×1884 mm for Serbian operators and 1106×1040×1790 mm for Libyan operators when using univariate approach, while multivariate approach provides more precise and comfortable accommodation within 1327×1123×1926 mm for Serbian operators and 1203×1090×1830 mm for Libyan operators. Accordingly, our survey shows that percentile models include less than the intended population proportion in the design problem with few dimensions and depends on correlations among them.
A number of problems are solved through modeling the crane operator workspace and it has been shown that cabins with different dimensions have to be offered to Serbian and Libyan markets.
先前的研究表明，收集和分析起重机操作员的人体测量特征对于操作员的舒适度、健康和工作能力非常重要，同时从性能、生产力和安全性方面来看也是如此。
本调查的首要目的是收集塞尔维亚起重机操作员最新的人体测量数据，并首次在利比亚收集这些数据。本调查的第二个目的是比较所收集的数据。第三个目的是为塞尔维亚和利比亚的起重机操作员驾驶的驾驶室内部空间建模。
共收集了 83 名塞尔维亚起重机操作员和 50 名利比亚起重机操作员的站立身高、坐姿身高、小腿长度、大腿长度、肩宽、臀宽、臂长、脚长和体重数据。采用描述性统计、相关分析和变量差异检验来检查塞尔维亚和利比亚起重机操作员之间的差异，从而进一步建模。使用来自两个样本的单变量和多变量操作员模型来完成对驾驶室内部的建模。
两个样本之间只有四个变量是共相关的。唯一没有统计学差异的测量值是肩宽。与利比亚人相比，塞尔维亚起重机操作员的几乎所有测量值都具有统计学上的更高值。使用单变量方法时，塞尔维亚操作员的最小驾驶室内部空间尺寸为 1207×1080×1884 毫米，利比亚操作员的最小尺寸为 1106×1040×1790 毫米，而多变量方法则提供了更精确和舒适的容纳空间，塞尔维亚操作员为 1327×1123×1926 毫米，利比亚操作员为 1203×1090×1830 毫米。因此，我们的调查表明，百分位模型在设计问题中包含的目标人群比例较少，且维度较少，并取决于它们之间的相关性。
通过对起重机操作员工作空间进行建模，可以解决一些问题，并且表明必须向塞尔维亚和利比亚市场提供不同尺寸的驾驶室。
