The type of takeup is selected in Belt Analyst™. The selection of takeup type and specifications Dynamic Analyst™ should agree with this.
At this time, Dynamics Analyst™ retrieves the takeup operating belt tension, sheaves and pulleys from Belt Analyst™ The user should check to confirm that other takeup data defining starting and stopping is input.
The takeup types utilized in older versions of Belt Analyst are --- "Auto": any type of takeup, such as gravity or active winch, that actively moves the takeup pulley
to maintain the desired belt tension, or "Manual": takeup with a fixed pulley where the takeup tension is manually adjusted.
The takeup type alternatives utilized in Dynamic Analyst™ are:
•Fixed ("Manual in previous program versions) is a takeup with a fixed pulley where the takeup tension is manually adjusted while not running.
•Vertical Gravity: ("auto" in previous program versions) is a type of takeup that actively moves the takeup pulley to maintain the desired belt tension. This is accomplished with a weight connected to the takeup pulley.
•Horizontal Gravity: ("auto" in previous program versions) is a type of takeup that actively moves the takeup pulley to maintain the desired belt tension. This is accomplished with a weight connected to the takeup pulley.
•Winch Always On: winch is always on tracking the deviation from target belt tension and adjusting actual tension.
•Winch Off/On: winch is normally off and fixed, it comes on to adjust actual tension when belt tension is greater than the high tension setting or lower than the low tension setting.
•Hydraulic: cylinder is normally fixed, it adjusts when belt tension is greater than the high tension setting or lower than the low tension setting
•Custom (Mechanical): takeup is always on tracking the deviation from target belt tension and adjusting actual tension.
Since BA and DA takeup type are input separately, the user must make a selection from pull down list to further define the takeup mechanism.
A brake can be applied to the rope in a gravity takeup, to the winch or to a mechanical takeup to stop the takeup movement; torque is limited by the brake capacity. If a brake is used, the brake force must be entered.
•Running takeup tension cannot be changed from BA value.
•The number of takeup pulleys cannot be changed from BA value.
•If an “auto” response curve is selected, number of sheaves and sheave drag are entered in BA.
•Running takeup tension cannot be changed from BA value.
•The number of takeup pulleys cannot be changed from BA value.
•If an “auto” response curve is selected, number of sheaves and sheave drag are entered in BA. Maximum belt tension is entered. The maximum line speed for paying out or pulling in is entered on the form.
•Expected running takeup tension is shown for reference; it cannot be changed from BA value.
•The number of takeup pulleys cannot be changed from BA value.
•The number of sheaves and sheave drag are entered in BA and cannot be changed in DA.
•The high and low tension settings for the dead-band are input. Maximum belt tension is entered.
•The maximum line speed for paying out or pulling in is entered on the form.
The response curve is automatically based on the input data; no user input is allowed.
•Running takeup tension cannot be changed from BA value.
•The number of takeup pulleys cannot be changed from BA value.
•If an “auto” response curve is selected, number of sheaves and sheave drag are entered in BA. Maximum belt tension is entered. The maximum line speed for paying out or pulling in is entered on the form.

Takeup pulley cannot move in simulation model.
•Running takeup tension cannot be changed from BA value.
