A construction elevator is provided. The construction elevator may include a car controller configured to direct the construction elevator to operate in a lifting operation or a descending operation. The construction elevator may further include a variable frequency drive coupled to a motor that are configured to operate the construction elevator in the lifting operation or the descending operation responsive to the direction of the car controller. Moreover, the construction elevator may include an onboard power source configured to provide power to the variable frequency drive and the motor to complete the lifting operation without needing to be recharged by an external power supply.
