TR75 - Overview

The TR75 is a track mobile high capacity stockpiling conveyor, which is strong and economical to run.

The TR75 is versatile and can be used on its own or with other screening plants.

Its portability allows it to work in confined spaces and also where heavier conveyors would find it impossible to manoeuvre.

The TR75 consists of a track base, feedboot, conveyor, powerunit and has a pendant remote control system.

Feedboot

The feedboot directs the sand, gravel, coal etc. onto the conveyor belt.

Conveyor

The main frame can be raised or lowered with a hydraulic cylinder giving alternate stockpiling heights. The conveyor belt can be either plain or chevron 3 ply 1050mm (42") wide.

Drive

Self contained 84H.P. JCB diesel engine and cast iron hydraulic pumps driving cast iron motors.

TR75 - Options

• Optional Deutz or Cat Engine

• Enclosed Skirting
• Radio Controlled Pendant

TR75 - Advantages

• Capable of handling up to 550TPH.
• Quick set up time typically under 20 minutes.
• Track mobile unit
• High performance hydraulic system.

TR75 - Applications

• Crushed stone
