ABSTRACT:
BACKGROUND
1. Field of Invention
This invention relates to the lifting and moving of fire suppression agent storage cylinders used within the fire protection industry.
2. Description of Prior Art
Fire protection equipment manufacturer's commonly supply their distributors with fire suppression agent storage cylinders. These storage cylinders can have a gross weight of approximately 1800 lbs when filled with a fire suppression agent. The storage cylinders are commonly shipped on a wooden pallet to facilitate handling during shipping. Other than utilizing a forklift or a crane, there has not been a simple device invented to facilitate the distributor nor the end user in removing these cylinders from the shipping pallet or moving these cylinders to their planned location.
SUMMARY
A device with a frame, a clamping device, a plurality of wheels and a plurality of lifting jacks in combination provides a means of lifting and moving a fire suppression agent storage cylinder.
OBJECTS AND ADVANTAGES
The objects and advantages of my invention are:
(a) to provide a safe means of lifting a fire suppression agent cylinder from the shipping pallet.
(b) to provide a safe and efficient means of moving a fire suppression agent cylinder without the need for a forklift or a crane.
Further objects and advantages are to provide a cylinder lifting unit that gives a fire protection contractor or an end-user the ability to safely move a fire suppression agent cylinder. To provide a safe working environment for the contractors employees thus reducing the amount of insurance and workman's compensation claims. To provide a cylinder lifting unit that is compact and easily transported, reducing the amount of heavy equipment needed when installing and servicing these cylinders. To provide a cylinder lifting unit that is able to pass through a standard size door while being used to move a fire suppression agent cylinder. To provide a cylinder lifting unit that will make it easier for a fire protection contractor to utilize these large cylinders within their fire suppression system design, thus allowing the manufacturer and the fire protection contractor to sell more of these large cylinders. Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.
