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.

Belt conveyors play an important role in the dry bulk material handling process. Speed control is a promising method of reducing the power consumption of belt conveyors.

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.

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 proportional to the Conveyor Drive Load. When the belt is empty, a low tension would suffice. When the belt is full a higher tension is required. During Start-Up an even higher tension is required.

These risks are associated with the lifting and securing of the conveyor Gravity Take-Up Units (GTU) masses on multiple conveyors. Carnac investigated six options identified during the initial site visit as follows: Option 1 - Pinning the GTU mass for maintenance activities; Option 2A - Permanently installled winch system with integral winch;

Automatic Hydraulic Takeups for Belt Conveyors. Post navigation. ... 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. ...

Winch & Loop Take Ups versus Gravity Towers The most common method to provide tension control on long conveyors is the gravity tower.

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 …

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.

The required take-up length is calculated as follows, where SSp= 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 calculations

This device will take up the stretch in the conveyor belt and keep proper tension at the drive pulley to reduce slippage. A dynamic type, like a gravity take-up, is generally preferred but not always practical due to space or cost. Martin Screw Take-Up Frames are a good solution for these applications. Martin offers several types of frames that ...

Gravity Take-Up Belt Tension problem solvers. Belt tension on belts over 220′ can be an issue. Create excessive belt stretch or additional belt tension with our gravity take-up assemblies where needed. They are available in both under and over slung configurations, and can be retrofitted to existing applications if needed.

6 Claims. (Cl. 198139) This invention relates to new and useful improvements in gravity type take-up mechanisms for belt conveyors and deals more particularly with horizontal type take-ups for use in connection with belts having an unusually great variation in their lengths during operation of the conveyors.

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

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 ...
