Hoist properties

Rotation

Rotates the hoist object, as well as the basic labels

General

Hoist ID

Provide a unique identifier for labels and paperwork. If blank, a value is automatically assigned when calculations are run (Braceworks required).

Hoist Name

Provide an alpha-numeric identifier to display on the hoist. Typically, this is the hoist type.

Position

Displays the name of the associated rigging object, if the hoist is attached. Optionally, attach this object to a rigging object, or change the rigging object association, by entering the Position Name of the rigging object. Delete the name to break the association.

For other methods to attach loads, see Making the attachment.

Geometry

High Hook Height

Determines the location of the upper hook (the fixed end of the hoist that attaches to the lifting structure) by setting the distance from the floor to the hook. The high hook may be located on the motor or on the end of the chain, depending on the Hoist Position.

Low Hook Height

Determines the location of the lower hook (the end of the hoist that attaches to the structure being lifted) by setting the distance from the floor to the hook. The low hook may be located on the motor or on the end of the chain, depending on the Hoist Position.

Adjusting this height also moves any attached loads.

Hook to Hook

Displays the distance between the high hook and the low hook

Load Trim

Specifies the height of the load being lifted by the hoist, measured from the floor to the bottom of the load

Trim at Bottom of Truss

Displays the height of the truss being lifted by the hoist, measured from the floor to the truss bottom edge. When the truss is rotated, the lowest height on the connection point of the truss is shown.

Trim at Top of Truss

Displays the height of the truss being lifted by the hoist, measured from the floor to the truss top edge. When the truss is rotated, the topmost height on the connection point of the truss is shown.

Low Hook to Load Trim

Specifies the distance from the bottom of the load to where the low hook attaches to the load. This offset distance accounts for the height of the load and any pick-up device used for the attachment.

This field is automatically populated when a Pick-up Symbol is specified.

Load Trim + Low Hook to Load Trim = Low Hook Height

Distance Trim Top Truss

Displays the distance between the top edge of the truss (Trim at Top of Truss) and the top of the hoist (High Hook Height)

Maximum Chain Length

Displays the maximum chain length available for the hoist

Properties

Chain Runners

Specifies the number of cable supports required on the hoist for the power, audio, and data cables in a moving truss application

Speed

Indicates the lifting and lowering speed of the hoist motor

Phasing

Indicates the power supply type required by the hoist (three phase or single phase), for all hoist types except Block & Fall

Voltage

Indicates the voltage required by the hoist, for all hoist types except Block & Fall

Connector Type

Select the type of controller connection; this does not apply to Block & Fall hoist types

Notes

Add a note for informational purposes

Total Weight

Displays the calculated weight of the hoist (based on the Hoist Weight) and its chain (based on the Chain Weight).

This value represents the “dead load” of the hoist.

Hoist Weight

Indicates the weight of the hoist without the chain.

Confirm that this weight is correct for your specific hoist.

Chain Weight

Indicates the weight of the chain per unit of distance

Distro/Port

Specifies the connection location on the controller; this does not apply to Block & Fall hoist types

Structural

Capacity

Indicates the maximum allowed total weight for the hoist, for use in calculations (Braceworks required)

High Hook Force

Indicates the total force applied to the hoist, including the hoist’s “dead load,” or Total Weight 

Low Hook Force

Indicates the total force applied to the hoist, not including the hoist’s “dead load,” or Total Weight 

High Hook Weight Equivalent

Displays the High Hook Force as a weight value, including safety factors.

This parameter was formerly known as the Total Point Load.

Low Hook Weight Equivalent

Displays the Low Hook Force as a weight value, including safety factors

Chain Shorten

Allows the chain length to be adjusted for calculation purposes (Braceworks required). Enter a positive number to shorten the chain by that value, or a negative number to lengthen the chain by that value.

Cross Section

Displays the associated cross section for Braceworks structures

Select Cross Section

Opens the Select Cross Section dialog box, to select or specify the cross section for the hoist chain.

Sets: Select a predefined manufacturer cross section from the list, or select <Rigid> to indicate the use of a generic cross section (a generic cross section assumes that the cross section is rigid for all calculations, Braceworks required). For these selections, no further information can be entered since the selected cross section data is used. Select Custom to enter custom cross section data in the rest of the dialog box.

Name: Provides a name for the cross section for use in reports.

Cross Section Area: Specifies the total area of the cross section.

Allowable Force: Sets the maximum allowable force that can be applied to the cross section.

Material: Specifies the type of material that the cross section chain consists of; select from the available options.

Hoist Position

Controls whether the motor portion of the hoist is shown in the top or bottom position, or is not shown in the drawing.

This setting determines where the "dead load" of the hoist is calculated (Braceworks required). For example, you can reduce the workload on the roof by selecting Hoist Down, placing the dead load of the hoist on its attached truss.

When Hoist Up is selected, the hoist’s attached load moves as well.

Reference Point

Origin

Select the hoist origin to use as a location reference, or use the drawing origin as the reference.

If the name of the hoist origin changes, you must update the selected Origin.

X/Y

Displays the X and Y coordinates of the hoist relative to the selected Origin; these coordinates display on the hoist when Show Measurement Label is selected

Show Measurement Label

Displays the coordinates and the direction relative to the selected Origin

Measurement Label Pos X/Y

Controls the location of the measurement label, which can also be adjusted with the label control point

Display

Show ID label

Displays a basic label showing the Hoist ID and the High Hook Force, if calculated (Braceworks required).

Hoists used with Braceworks receive color-coded label fills to indicate their calculation status; see Displaying and correcting errors.

Show pick-up symbol

Displays the 2D portion of the selected pick-up symbol in 2D and schematic views. Move the control point to reposition the pick-up symbol.

In 3D views, the 3D portion of the symbol displays by default.

Realistic chain (slower)

Draws each link of the hoist chain in 3D views, which is more realistic but may take longer to display

Pick-up symbol scale

Scales the pick-up symbol; enter the scale factor

Hoist Symbol Scale

Scales the hoist symbol; enter the scale factor

Hoist Symbol

Displays the symbol that represents the hoistn, and opens the Resource Selector to select a different symbol; double-click a resource to activate it

Classes

Opens the Classes dialog box, to specify class naming for the basic hoist labels (the ID label and measurement label), and the hoist chain. This allows the hoist labels and chain to be set to visible, grayed, or invisible.

Use the standard class, select a class from the list of classes present in the drawing, or create a new class.

Use Standard Classes: Sets the class name for the label to the standard.

ID Label: Specifies the class name standard to apply to the hoist label.

Measurement Label: Specifies the class name standard to apply to the measurement label.

Chain: Specifies the class name standard to apply to the chain.
