SPECIAL RANGE
The M412 crawler mounted side discharge loader is a low profile high output machine. The latest development in the fields of hydraulics and fabrication and underground work are considered while designing the loaders and they are developed to offer maximum benefit to the mining industry. Flameproof electricals make them suitable for operation in gassy mines.
SPECIAL FEATURES Outstanding power/weight ratio; Low heat generation; Low center of gravity; Low specific base pressure; Fail safe parking brake; Track aligning guards; powerful flood lights; emergency stops; deadman switch; heavy duty construction; Protection of sprocket from ingress of dust.
STATIC SHAFT DESIGN
The manufacturer reserves the right to change the specifications and/or design, of this machine at any time without notice.
STUB PULLEY DESIGN
Pulleys are dimensioned according to the characteristics of each conveyor and may be designed to meet a great variety of construction methods. For 40 years TRF has designed and manufactured pulleys, using materials of the highest quality in a production process employing advanced technology. This together with the application of the Quality Assurance system certified to ISO 9001 contributes to the production of high quality products offering dependable, long life performance in the field and appreciably reducing maintenance costs.
The other variants of Side Discharge Loaders available are = Extra Low Height - 1.0 cum bucket capacity. = Standard Height with CRD arrangement - 1.0 cum bucket capacity.
