Incline belt conveyors feature a center drive, gear motor, and take-up with a single or double nose. And instead of using a smooth-surfaced belt, this type of conveyor has a rough surface on the belt, ideal for carrying products up or down.
The subsections of this item cover design considerations of a take-up system for a bulk material handling belt conveyor system or project. Take-up Movement The purpose of take-up devices in belt conveyors is to establish and maintain a predetermined level of tension in the belt.
The design of belt conveyor systems has been one of the most common occurrences in the South African mining field for over one hundred years. Conveyors are seen on virtually all mining installations, and are the biggest problem for the plant maintenance engineer, being the cause of most plant shutdowns.
, required at the drive of a belt conveyor, is derived from the pounds of the effective tension, T e, required at the drive pulley to propel or restrain the loaded conveyor at the design velocity of the belt V, in fpm: (1) To determine the effective tension, T e …
Although conveyors are traditionally employed for horizontal movement, when a product needs to travel down, spiral conveyors are a top option. They take up a fraction of the floor space compared to a traditional conveyor, resulting in potentially significant financial savings.
Vertical reciprocating conveyors provide a variety of operational benefits, including. Safe and efficient movement of products, loaded pallets, and equipment. VRC systems require no manpower or forklifts for use and can be loaded with pallet jacks. They cost less to operate and maintain than freight elevators no inspections necessary.
Douglas take-ups are designed to help take up belt stretch as it relates to the belt conveyor system. Take-ups are available in the following styles: Slide Tube Take-Ups®, top angle protected screw, heavy duty top mount, light duty top-mount, heavy duty center pull, wide slot center pull and the Scissor Pivot™ Gravity Take-Up Assemblies.

For the best accuracy, use a vertical gravity take-up. If that is not practical or possible, use a horizontal gravity take-up. The use of the screw type take-up should be limited to conveyors with pulley centers of less than 18 m (60 ft). Material Feed Point Some conveyor systems require that multiple feed points be in use at the same time.

The first of these is the vertical gravity type which utilizes a large weight to move the takeup pulley, operating through a system of sheaves and cables. In its simplest form the counterweight must move 10 ft, vertically to provide 10 ft. of horizontal pulley travel.

It is used in inclined belt conveyors to prevent belt conveyor movement in the reverse direction. Take-up: It is necessary to maintain tensions at the point to prevent slippage on the drive pulley. Types of take-up: There are two types of take-ups. Manual or screw type; Vertical gravity take-up or Horizontal gravity take up; Manual or screw type:
Use gravity feeds when possible. You can substitute gravity conveyor for power conveyor in the right situation, creating both equipment cost reductions and energy savings. Mixing power and gravity units to conserve energy and reduce costs is usually possible. Design with energy savings in mind. Use long, straight runs with fewer drives.

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 (Ex.: Gravity type automatic take up ...
Take ups: A belt conveyor may have a mechanical (screw type) or counterweight (gravity type) take up. The latter may in turn be divided into carries – type (sometimes called horizontal and vertical. In the screw take up the tensioning pulley simultaneously serves as deflecting til or pulley and rotates on a fixed shaft (best design) or in ...
Belt Conveyor Capacity Table 1. Determine the surcharge angle of the material. The surcharge angle, on the average, will be 5 degrees to 15 degrees less than the angle of repose. (ex. 27° - 12° = 15°) 2. Determine the density of the material in pounds per cubic foot (lb/ft3). 3. Choose the idler shape. 4. Select a suitable conveyor belt ...
You have 90 m long conveyor equipped with gravity take-up. If you do not wish to go into elaborate design steps, you may adopt following suggestions. 1) The take-up system to be mounted in a 4 legged trestle. The gantry from both ends will be resting on both the sides. 2) The trestle will have top member to provide support to the gantry.
If, for example, T2 = 1,000 lbs, in the case of a counterweighted take up, the weight of the counterweight must be 2,000 lbs. That is because the 2,000 lbs provided by gravity will be resisted with an equal and opposite force of 1,000 lbs …
this is an innovative project in a sense that a hybrid of both horizontal and vertical gravity take-up system has been developed and implemented on a vertical or festoon system to solve the following ongoing problems and rio tinto non compliance issue on some old conveyors within greater paraburdoo operation;

Take Up Travel – 600 mm Type of Take up – SCREW 5. DESIGN OF BELT CONVEYOR The design of the belt conveyor must begin with an evaluation of the characteristics of the conveyed material and in particular the angle of repose and the angle of surcharge. The angle of repose of a material, also known as the "angle of natural friction" is the
counterweight impact arresting (gravity take up arresting) TG is a cost effective way to arrest a falling gravity take-up counterweight. In the case of conveyor belt failure where the counter wweight falls, there is potential for damage to the structure and/or counterweight itself.

To prevent belt slippage, portable conveyors are designed with a mechanical take-up frame. These integrated tools allow the operator to adjust belt tension to the drive pulley. Superior designs and manufactures a set of six unique designs for pillow block, wide slot or top angle bearings in top or side conveyor mounting positions.
Conveyor Take-up Arrangement: All belt conveyors require the use of some form of take-up device for the following reasons: To ensure adequate tension of the belt leaving the drive pulley so as to avoid any slippage of the belt To ensure proper belt tension at the loading and other points along the conveyor To compensate…
moving freely. The take-up unit can only be installed after the drive unit. Such a design cannot be used with a reversible conveyor. The take-up range is a function of the effective pull, the required force F 2, the belt length L g, its delivery tolerance Tol, the tension reserve Z and the belt type. Take-up range for load-dependent take-up ...
