Handymax or Supramax is a naval architecture term for a bulk carrier, typically between 35,000 and 60,000 metric tons deadweight (DWT).

A handymax ship is typically 150–200 m (492–656 ft) in length, though certain bulk terminal restrictions, such as those in Japan, mean that many handymax ships are just under 190 meters (623 ft) in overall length. Modern handymax designs are typically 52,000-58,000 DWT in size, have five cargo holds, and four cranes of 30 tonnes (33.1 ST; 29.5 LT) lifting capacity.

大灵便型散货船（Handymax bulk carrier)，又称大灵便型，是一种载重35000到60000吨的散货船[1]，和灵便型散货船一样，大灵便散货船一般都自备装卸设备，载重量适中，吃水较浅，可以在一些比较小的港口进行装卸作业，适应性较强。

一般来说，现代的大灵便型散货船，一般船长150到200米，载重52000到58000吨，有五个货仓，和4个30吨的起重机，一般采用单机，单桨驱动，机舱置于船尾，随着对环保和安全性的提要求日益提高，新船多采用双层壳体结构。

根据1992的统计，全球载重5万吨级以下的灵便型船占干散货船总吨位的48.4%，总吨位约10100万吨[2]，是对国际航运业有着举足轻重的影响。波罗地海航交所根据大灵便型散货船的运价发布了波罗的海轻便型指数，是世界三大航运指数之一。
