  • Publication number: 20230136869
    Abstract: A battery charging device may detect a connection, from a first machine, to receive an electrical charge to charge a battery of the first machine. The battery charging device may receive, via the connection, machine information regarding the first machine. The battery charging device may identify, based on the machine information, a second machine associated with the first machine. The battery charging device may determine a first recommendation associated with the first machine and a second recommendation associated with the second machine. The first recommendation may identify at least one of a component or a service recommended for the first machine. The second recommendation may identify at least one of a component or a service recommended for the second machine. The battery charging device may provide the first recommendation and the second recommendation while providing the electrical charge to the first machine.

  • Patent number: 9550407
    Abstract: A roof for a cab of a machine includes a roof surface with a rearward incline having a front portion higher than a rear portion. The roof surface has a recessed portion at the rear portion that receives a Heating Ventilation and Cooling (HVAC) unit. The recessed portion includes a rearward facing sidewall with a rearward incline, such that an upper end of the rearward facing sidewall is closer to the front portion than a lower end. The rearward facing sidewall has a lateral opening, a pair of lateral sidewalls, and a base with a rearward incline, such that a front end of the base is higher than a rear end. The base has an upright opening with a ridge protruding upward, defining a perimeter of the upright opening. The rearward facing sidewall, the pair of lateral sidewalls, and the base, define a contiguous peripheral portion of the recessed portion.
