Stand-off brackets: Dictated by OSHA Standard 1910.27(c)(4) stand-off brackets must be at least 7" (180 mm) longer than the farthest obstruction for clearance on the back side of ladder. This means that if there is a 4" (100 mm) gutter projecting from the side of a building, a fixed ladder would have to have standoff brackets that were at least ...
Either way, designed to keep clothing from fouling the chain. See also Skirtguard, Bashguard. Chainring: (one of the) front gear(s), attached to a crank; Chainset: see Crankset; Chainstay: a pair of tubes on a bicycle frame that runs from the bottom bracket to the rear fork ends; Chain tensioner: a device to maintain proper chain tension
An extension ladder. A ladder is a vertical or inclined set of rungs or steps commonly used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top.
Chain conveyors use an endless chain both to transmit power and to propel material through a trough, either pushed directly by the chain or by attachments to the chain. The chain runs over sprockets at either end of the trough. Chain conveyors are used to move material up to 90 metres (300 ft), and typically under 30 metres (98 ft). [1]: 271
A resistor ladder is an electrical circuit made from repeating units of resistors, in specific configurations. An R–2R ladder configuration is a simple and inexpensive way to perform digital-to-analog conversion (DAC), using repetitive arrangements of precise resistor networks in a ladder -like configuration.
Ladder Dogs (in the form of pawls) are used on extension ladders to temporarily anchor their sections to one-another. [3] Table saw Pawls are used on table saws to prevent a workpiece being sawn from kicking back. [4] Transmission A parking pawl is a device in an automobile automatic transmission which prevents it from moving when the vehicle ...
Ladder notation is best suited to control problems where only binary variables are required and where interlocking and sequencing of binary is the primary control problem. Like all parallel programming languages , the sequential order of operations may be undefined or obscure; logic race conditions are possible which may produce unexpected results.
A long put ladder is also called a bear put ladder. [8] A short put ladder is also called a bull put ladder. [9] A ladder can be seen as a modification of a bull spread or a bear spread with an additional option: for instance, a bear call ladder is equivalent to a bear call spread with an additional long call. A bull put ladder is equivalent to ...
