Technical DATA<\/p>\n

ZDL202 underground loader<\/p>\n

 <\/p>\n

 <\/p>\n

ZDL202 underground loader <\/b><\/strong>:Trackless shovel loading and short distance transportation equipment<\/b><\/strong><\/p>\n

\u00a0<\/b><\/strong><\/p>\n

The\u00a0ZDL202 underground loader<\/b><\/strong>\u00a0mainly used in conjunction with mining trucks in underground excavation and mining operations. Shovel loading of ore and various materials can greatly improve operational efficiency and is an important equipment for achieving trackless mining.<\/p>\n

 <\/p>\n

This model has an articulated frame and an S-shaped anti six link mechanism for the working mechanism. The driver’s seat is located on the front body and has a protective driving shed. The swing mode is a rotary bearing, and the front axle is equipped with an anti-skid differential.<\/p>\n
