A lean-to rigging apparatus is described for installation in a shaft, such as an elevator shaft, having a wall and including at least one sill opposite the wall. The rigging apparatus includes a spanning beam, a sill support structure, a wall support member, and a hoist connector. The sill support structure on a first end of the spanning beam is designed to seat against a sill in the in the shaft while the wall support member on a second end of the spanning beam abuts against the opposite shaft wall. The sill support structure is rigidly connected to the spanning beam in a hingeless configuration and can seat against a sill in a plurality of seating positions. These seating positions allow the rigging apparatus to be positioned in a plurality of angles and therefore to be installed in shafts of different dimensions. The hoist connector is configured to allow a connection to a hoist device for hoisting various materials from one level to another within the shaft.

A vehicle includes an auxiliary battery configured to power an electrical accessory, a traction battery configured to provide power to propel the vehicle, a winch including a motor and cable, and a controller configured to, responsive to a requested torque of the motor being less than a threshold, initiate transfer of power to the motor from the auxiliary battery, and initiate transfer of power to the motor from the traction battery otherwise.

A support arrangement for a fluid monitoring system is provided, configured for being secured within a vertical shaft and for facilitating positioning of a fluid monitor suspended therefrom. The support arrangement includes an attachment arrangement to be secured to a vertical access shaft of an open channel fluid transport system, a cross rail assembly including a cross rail and being configured to be mounted to the attachment arrangement for being supported thereby, and a lifting assembly mounted on the cross rail and configured for suspension therefrom of the fluid monitor along a vertically-extending suspension axis. The cross rail is configured to be rotatable about a vertical axis when at least partially received within the attachment arrangement. The lifting assembly is configured to be selectively secured to one of a plurality of lateral positions along the length of the cross rail.

Provided is a chain block with which wheel cover strength can be improved while inhibiting an increase in cost, without the need for separate reinforcement members. A chain block is provided with a wheel cover which is attached to a frame member, and which covers a hand-chain wheel having a hand chain looped thereover. A plurality of fixation holes for having fixation members inserted therethrough during attachment to the frame member are provided in peripheral edge sections of end-surface sides of the wheel cover, said end-surface sides being disposed facing the frame member. Wrap-around portions are provided to wheel-cover side surfaces which intersect the end surfaces, said wrap-around portions being formed so as to surround, at an angle exceeding 90, the fixation holes in the peripheral direction of the fixation holes.

A device and process for lifting and transiting a heavy object from a confined space is provided that increases the efficiency of repair of malfunctioning heavy appliances illustratively including hot water heaters. The device and process are able to adapt to a variety of obstacles and spatial challenges inherent in confined spaces where heavy appliances are frequently located. Additional benefits provided by the device and process are to reduce the risk of injury to a maintenance person working to repair a malfunctioning heavy appliance by allowing for the lifting and transiting of the appliance away from the confined space, thereby allowing for easier access and a larger working environment, while also reducing the risk of damage to property within, or in proximity to the confined space where a heavy appliance is located.
