Abstract
A floor service jack includes a battery and a control panel provided at a distal end of a handle of the jack for electro-mechanically or hydraulically controlling a lift arm to raise and lower a vehicle for servicing without exposure to an undercarriage of the vehicle to replace the battery or to operate the control panel.
Claims15
A floor service jack, comprising:
- a frame having a forward end and a rearward end, the frame including a plurality of wheels attached proximate the forward end, the frame being configured for positioning under a vehicle;
- a lift arm having a saddle depending therefrom, the lift arm rotatably disposed in the frame;
- a handle having a proximal end and a distal end, the proximal end movably attached to the frame, the distal end being spaced apart from the vehicle;
- a battery disposed proximate the distal end of the handle;
- a control switch in electrical communication with the battery, the control switch disposed proximate the distal end of the handle;
- an electro-hydraulic pump disposed proximate the frame, the electro-hydraulic pump in electrical communication with the battery;
- and
- a hydraulic cylinder connected to the lift arm and being in hydraulic communication with the electro-hydraulic pump, wherein, when the control switch is activated, the battery powers the electro-hydraulic pump, the powered electro-hydraulic pump thereby charging the hydraulic cylinder to an internal pressure not exceeding ten thousand pounds per square inch to change a position of the lift arm and the saddle.

A floor service jack, comprising:
- a frame having a forward end and a rearward end, the frame further comprising a plurality of wheels attached proximate the forward end, the frame being configured for positioning under a vehicle;
- a lift arm having a saddle depending therefrom, the lift arm rotatably disposed proximate the frame;
- a handle having a proximal end and a distal end, the proximal end movably attached to the frame, the distal end being spaced apart from under the vehicle;
- a battery disposed proximate the distal end of the handle, the battery being rechargeable or changeable from the distal end when the frame is under the vehicle;
- a control switch in electrical communication with the battery, the control switch disposed proximate the distal end of the handle;
- and
- an operating assembly connected to the lift arm, wherein, when the control switch is activated, the battery powers the operating assembly to adjust a position of the saddle.
