Abstract
A vacuum lifting device and method of manufacture thereof includes a vacuum generator for generating a vacuum. The vacuum lifting device also includes a base having opposite first and second sides and a vacuum lifting chamber provided on the second side of the base and having a suction end. The vacuum lifting chamber is in fluid communication with the vacuum generator, wherein the vacuum generator creates negative pressure within the vacuum lifting chamber. A gasket is coupled to the suction end of the vacuum lifting chamber and is configured to create a vacuum seal with a surface of an object to be lifted by the vacuum lifting device.
Claims25
A vacuum lifting device comprising:
- a vacuum generator for generating a vacuum;
- a base having opposite first and second sides;
- a vacuum lifting chamber provided on the second side of the base, the vacuum lifting chamber having a suction end, the vacuum lifting chamber being in fluid communication with the vacuum generator, wherein the vacuum generator creates negative pressure within the vacuum lifting chamber, and
- a gasket coupled to the suction end of the vacuum lifting chamber, the gasket being configured to create a vacuum seal with a surface of an object to be lifted by the vacuum lifting device.
A vacuum lifting device comprising:
- a vacuum generator for generating a vacuum;
- a base having opposite first and second sides;
- a vacuum lifting chamber provided on the second side of the base, the vacuum lifting chamber having a suction end configured to create a vacuum seal with a surface of an object to be lifted by the vacuum lifting device;
- and
- a vacuum reservoir separate from the vacuum lifting chamber, the vacuum reservoir being in fluid communication with the vacuum generator to create a negative pressure within the vacuum reservoir, the vacuum reservoir being connected to the vacuum lifting chamber by a conduit, wherein airflow between the vacuum reservoir and the vacuum lifting chamber is controlled through the conduit.
A method of manufacturing a vacuum lifting device comprising:
- providing a vacuum lifting chamber having a suction end configured to be set on an object to be lifted;
- providing a vacuum reservoir;
- providing a vacuum generator in fluid communication with the vacuum reservoir, the vacuum generator being configured to create a vacuum in the vacuum reservoir;
- coupling a conduit between the vacuum lifting chamber and the vacuum reservoir;
- and
- coupling a valve to the conduit, the valve controlling airflow between the vacuum lifting chamber and the vacuum reservoir.
