Abstract: An aerial system for equipment such as but not limited to a crane, derrick, bucket truck, man lift, and the like, includes a mounting platform for mounting an aerial device on a ground-engaging chassis. The mounting platform is an electrical insulator. In use, a vertical height or position of the mounting platform may be fixed.

Abstract: An aerial device system includes an adjustable railing and a coupler. The adjustable railing is positionable around at least a portion of a base platform and is movable between a stowed position and a deployed position. A height of the adjustable railing in the deployed position is greater than a height of the adjustable railing in the stowed position. The coupler is communicatively coupled to the adjustable railing and is configured to detect a position of a component of an aerial device of the aerial device system and move the adjustable railing based on the detected position of the component of the aerial device. A method of controlling a cab guard safety system for the aerial device includes detecting the position of the component and moving the adjustable railing to a stowed position or a deployed position based on the detected position of the component.

Abstract: A transmission including a torque converter to transfer power from a driving engine to a driven device through a series of fluidly-activated clutches, particularly for use with industrial applications. By using a self-contained fluid system to engage the clutch at the idle speed of the driving engine, the transmission is provided with a positive neutral feature. The transmission is adaptable to all industrial engine housings. Additional optional features of the transmission include an auxiliary drive, a reverse and single or additional forward gears, and a fluid cooler. The transmission further includes a transmission output shaft supported by a bearing assembly that may be designed for side loading. The transmission provides the benefits of increased performance in torque demanding applications, self-lubricating features that eliminate grease fittings, load dampening, an auxiliary drive, and a throttle/clutch engagement system that eliminates clutch damage caused by improper high speed engagement.

Abstract: A ventilator is selectively configured so that it can automatically open and close its louvers according to the temperature in its environment or have its louvers manually positioned in either the open or closed orientation. The louvers are disposed in an air passageway that is defined by a housing. A bimetallic coil acts through a drive element and a linkage element to automatically open and close the louvers of the ventilator. A pair of override members have respective handles accessible to the user. Manipulation of the override members enables the user to override the automatic drive element to manually open and close the louvers.

Abstract: A ventilator opens and closes itself according to the temperature in its environment through the use of a bimetallic coil spring which acts through a drive element and linkage elements to open and close the louvers of the ventilator. The louvers are disposed in an air passageway that is defined by a housing, which defines a spring box to house the coil. The louvers are configured with an S-shaped cross section so as to provide positive engagement between the louvers when they are in the closed position. The drive element and a linkage element have rotation post with bifurcated flared heads that rotatably engage the louvers for simultaneous movement. A removable backframe has projecting tabs that fit into holes defined near the rear edge of the housing. The backframe has a closure surface for engaging a forward-extending free edge of the uppermost louver. The backframe also has a closure stop member that engages the lowermost edge of the bottom louver.
