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 in each of the two strands of conveyor belt.
Take-up pulley can now be used to take-up belt. 8. ROLLER BED CONVEYORS. When heavy total loads must be moved, it is best to use a conveyor bed with rollers (instead of regular conveyor bed). This is a Roller Bed belt conveyor.
Gravity Take-up Section: Normally supplied on conveyors in excess of 150' in length Conveyor Supports: Normally constructed in one welded assembly in lengths up to 25', supports longer than this are bolted construction and will require field assembly.
in a lengthening loop take up. A condition that is unique to mining is the continual expansion and contraction of conveyor lengths. This has led to the development of loop take up modules that can store up to 200 meters of belting. They consist of a number of transverse layers of belting operating through a series of pulleys.
Mar 24, 2017· A counterweight tension unit (often known as a gravity take-up unit) is the most widely used in many belt conveyors. In these units, the belt tension is provided by a properly calculated weight (usually installed in a special unit near the drive pulley at the head of the conveyor…

Oct 03, 2020· 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 provide extra length of belt when necessary for splicing purpose. Usually there are two types of take up arrangements.
Other styles of take-up frames are available but all use threaded rod to provide adjustment to the tail pulley assembly. As shown in figure A tension applied to the …
GTU SERIES GRAVITY TAKE-UP ASSEMBLIES Gravity take-up assemblies are typically required on conveyors exceeding 220'-0" in overall length where excessive belt stretch or additional belt tension may be required. Available for 18", 20", 24", 30", 36", 42", 48", and 54" belt widths. Standard 7 and 10 gauge formed and welded
Belt tensioning: The needed tension can be provided in a number of ways by suitable arrangement like pulling back the tail drum or idler pulley and also by providing 'drop-weight' or 'gravity take-up' device. Hydraulically or electrically powered automatic take-ups are also available which relay on a load-sensitive device to move the ...
Other styles of take-up frames are available but all use threaded rod to provide adjustment to the tail pulley assembly. As shown in figure A tension applied to the conveyor belt is accomplished by turning the adjustment nut on the take up assembly. There is another identical take up unit located on the opposite side of the take-up pulley.
The required take-up length is calculated as follows, where . S Sp = take-up length (m) L = conveyor length (m) ε = belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note: For long-distance conveyors, dynamic start-up …
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 ...
1. Fixed take up device that may be adjusted periodically by manual operation. 2. Automatic take up device (constant load type) Manual Screw Take Up: The most commonly used manual take up is the screw take up. 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 ...

• TAKE-UP LOCATION – This is the take-up location as a percentage of the horizontal centers of the conveyor. The 0% location is at the head and the location is at the tail. This will normally be for a fixed take-up head drive conveyor profile. The program defaults to the conveyor midpoint for gravity take-up profiles.
7. CONVEYOR TAKE-UP DEVICES In searching for Conveyor Take-Up Actuation, there are a variety of devices to choose from: a) Gravity Tower/Counterweight b) …
Gravity Take-up Features: Durable powdercoat finish. Various belt widths from 18"-54". Modular, bolt in place options. Shaft sizes, pulleys, and weight box …
Dan Cavallari Conveyor take-up is the process of adjusting the tension on a conveyor belt. Conveyor take-up is the process of adjusting the tension on a conveyor belt. This process prevents damage to the belt and other equipment within the conveyor system and prevents premature wear of components. The term "conveyor take-up" may also refer to a specific device used to control the tension of ...
