Conveyor layouts:
Belt conveyors can be designed for practically any desired path of travel. It should be noted that transfer between conveyors should be avoided where possible due to additional wear on the belts at the loading points. Some of the profiles shown below:
Horizontal Conveyor
Decline Conveyor
Inclined Conveyor
Overland Conveyor

Conveyor Take-up Arrangement:
All belt conveyors require the use of some form of take-up device for the following reasons:
Usually there are two types of take up arrangements.
In a screw take up system the take up pulley rotates in two bearing blocks which may slide on stationery guide ways with the help of two screws. The tension is created by the two screws which are tightened and periodically adjusted with a spanner. It is preferable to use screws with trapezoidal thread t decrease the effort required to tighten the belt.
The main problem with the use of manual take-up is that it requires a vigilant and careful operator to observe when take up adjustment is required. Perfect tension adjustment with this system is also not possible. For this reason these devices are used only in case of short conveyors of up 60 m length and light duty.
In automatic take up arrangement the take up pulley is mounted on slides or on a trolley which is pulled backwards by means of a steel rope and deflecting pulleys. The carriage travels on guide ways mounted parallel to the longitudinal axis of the conveyor, i.e., horizontally in horizontal conveyors and at an incline in inclined conveyors. Hydraulic, pneumatic and electrical take up devices are also used.
Automatic take-up has the following features:
