  • Patent number: 9725880
    Abstract: The present invention relates to an apparatus for controlling a cascaded hybrid construction machine system and a method therefor, which apparatus includes: a control part for controlling an electric motor for driving an actuator differently according to whether or not the actuator performs a recovery action and whether or not an energy storage device can be recharged; and a motor driver for driving or stopping the electric motor by switching under the control of the control unit, wherein when the actuator performs a recovery action for both the overcharged state and the failure state of the energy storage device, the motor for driving the actuator is temporarily stopped by the switching of the motor driver so as to restrain the recovery energy generated, thus protecting the hybrid power source system and keeping the operator safe as well as resolving the problem of the working time being increased due to the system's shutting off.

  • Publication number: 20170129563
    Abstract: Provided is a method for fastening a separation type tricycle in which a connecting pipe for connecting a front wheel part and a rear wheel part can be separated from and fastened to a head tube of the front wheel part, wherein the front wheel part and the rear wheel part are separated from each other by forming an ear-shaped groove, in which a handle bar can be put, in a right-side-open rectangular shaped plate fixed to the end of the connecting pipe so as to be used for attachment/detachment in a fastening device of the head tube, and then the end of a connecting bar for connecting the front wheel part and the rear wheel part is put on the handle bar by using the groove and another place is fixed thereto so as to set three wheels at the shortest distance therewith, thereby conveniently moving and storing the tricycle.
