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: To manage a fleet of vehicles efficiently, data is obtained concerning vehicle condition; some of this data is recorded in a data packet format on a vehicle and transmitted by radio from the vehicles to a base station, and under some circumstances, transmitted by the internet to a central data station where it is used to determine what should be done with the vehicles, such as for example to determine if the battery of a vehicle must be charged. The data may be transmitted from one vehicle to another vehicle before reaching the base station or the central data station. The data packets can indicate the vehicle to which the data applies, if the battery needs to be charged or replaced and can establish a priority schedule for the charging or replacement of the battery.

Abstract: A waste reducing device, such as a wood chipper, can include an infeed chute, a powered feed system, a powered cutting system, a discharge chute, and a safety device including an elongated structure positioned outside of and adjacent to the infeed chute of the wood chipper. The elongated structure of the safety device can be movable vertically downward and radially inward towards the infeed chute between a plurality of positions. An actuator can be operably connected to the elongated structure and have a plurality of operable positions corresponding to the plurality of positions of the elongated structure. In various ones of the operable positions, the actuator can permit or stop motive operation of the powered feed and cutting systems of the wood chipper. The safety device can operate independently of a feed system control bar.

Abstract: A spring clip for mounting a ventilator in an opening provided in a foundation or other wall structure. Preferably, two spring clips are used to retain the ventilator in the opening, one spring clip on each side of the ventilator. Each spring clip is made of resilient material and includes a front end adapted for attachment to the ventilator, a bulged intermediate portion which is deflected inwardly upon insertion of the ventilator in the opening, and a rear end located adjacent a side wall of the ventilator and which slides along the side walls as the bulged portion is deflected. The bulged portion presses against the side of the ventilator and a side of the opening in an elastic manner to retain the ventilator in the opening by frictional engagement. The need is eliminated for fasteners other than the spring clips in order to securely retain the ventilator in the opening. The need to modify the opening to allow the ventilator to be retained therein by conventional fasteners is also eliminated.
