Belt conveyor yang ditinjau menggunakan take up pulley jenis ini. Gambar 2.10 Take Up Pulley
A. Drive pulley now "pulls" belt in either direction. B. 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. Heavy total loads can be moved without using large motors ...
Answer: Conveyor The conditions of operation of a conveyor belt vary continuously with start-up, with running with varying load and stopping. It is crucial that the Take-Up Tension on a Conveyor Belt is adequate for all the varying conditions. The minimum required tension is directly proportion...
Conveyor Inclination – 10.36 0 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,
#1180 HDCP Catalog_#1180 HDCP Catalog 12/6/12 2:50 PM Page 70 Take-Up Frames Cross Reference A properly designed belt conveyor will require the use of a take-up device. This device will take up the stretch in the conveyor belt and keep proper tension at the drive pulley to reduce slippage.

is Tension Take-Up is often the limiting factor. 1.4. GRAVITY/COUNTERBALANCE TAKE-UP DEVICES Gravity/Counterweight Towers will always be the starting/reference point in most designs because they are the easiest to work out. Most Conveyor Design Programs cater solely for Gravity Towers. However gravity towers generally involve quite a
With gravity-operated take-up systems the tensioning weight must generate the force F 2 in order to achieve satisfactory grip by the belt on the drive drum (spring-loaded, pneumatic and hydraulic take-up devices operate in similar fashion). The tensioning weight must be capable of moving freely. The take-up unit can only be installed after the ...

• 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. Get More
These belt conveyors can be run at various inclined angles, typically between 0°- 20° (30° with cleated/chevron belting). For conveyors that operate beyond this incline, steep incline conveyors, which can operate at angles all the way up to 90°, are also available. The diagram below shows the relationship between conveyor center-to-center ...
If a gravity take-up can be used on such conveyors in order to reduce the variation in belt tension, it will greatly enhance the performance of the belt scale system. An electronic incline compensating device, where measurement of incline angle and automatic compensation of conveyor load readings is performed, remains a must.
• 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.
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.
adjusting mechanical take up units on bulk material handling belt conveyors under 200 feet long; as well as related belt tracking issues. A mechanicaltake -up uses threaded rod and nuts to create displacement of the tail pulley assembly. Other styles of take-up frames are available but all use threaded rod to
5. Gravity take up tensioning arrangement is provided at the boot section of bucket elevator. 6. In case of higher temperature material, buckets are mounted on chain, similarly for lower temperature application, buckets are mounted on belt. 7. Self supporting design can be provided up to 25 meters and above it calls for external support. 8.
A Take-up device provides the means to maintain the proper tension on and to adjust the length of the belt to compensate for stretch ensuring the continuity of transmission. Gravity take-up A Winch was applied instead of Crane to lift up the counterweight block to relief the belt ten-sion for maintenance events. Usually the Win-
Wt of Counter wt in of Gravity Take up. Dear all, I have observed that the weight of counter weight is generally 50% higher than the weight required by design or by reputed belt designing softwares. If the design requirement is 4 MT, the total weight in GTU provided is 6 MT. I am refering to troughing belts within steel plants.
1 The diagram shown below represents the various operating tensions (in pounds) for a belt conveyor with a gravity take-up, a center-to-center length of 800 feet, and a belt velocity of 500 fpm. The drive is snubbed with an angle of contact = 190°, the belt width is 24 inches, and the conveyor lifts material through a vertical height H = 40 feet ...
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 ...

Several different types of gravity take-up systems are available to best suit the application of the conveyor. A mid span hanging gravity take-up, a tail section counterweighted take-up, a horizontal counterweighted take-up. The 1-1/2 to 2% of the center distance mount of take-up travel is a good rule for gravity take-ups.
