Method for raising or lowering an object by davit apparatus with height adjustment feature

Abstract

The present invention relates to a method of providing an adjustable arm davit apparatus with height adjustable feature including, a base member, a shock absorber, a boom member, an adjustable arm, a winch assembly and a cylinder assembly. The boom member comprises a first member hingedly mounted on the base member and a second member mounted on the first member to adjust a height of the apparatus via the cylinder assembly disposed at the boom member. The adjustable arm is engaged to frontal ends of the boom member. The winch assembly positioned on the boom member for supplying a cable via a plurality of pulleys to attach the target object. The winch assembly is actuated to raise or lower the target object from the target location.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention disclosed herein generally relates to a method for raising or lowering an object. More particularly, the invention disclosed herein relates to the method for raising or lowering a target object from a target location by means of a davit apparatus with height adjustment feature.BACKGROUND[0002]Davits are lifting devices generally used on marine platforms, for example, decks of ships, loading decks of ports, etc., for supporting, raising, and lowering heavy loads. These heavy loads range from lifeboats, vehicles, containers, anchors, other products, for example, tires, etc. Moreover, they are used to lift small boats. Typically, davits utilize winch assemblies to lower or raise the load. These loads can be raised or lowered only if they are positioned at a particular height. Moreover, these davits are not adjustable from the positions where they are installed, for example, on the deck of the ship. Since the height of a deck of a ship...

AI Technical Summary

Benefits of technology

The patent describes a hydraulic / electrical cylinder that can extend and retract to move a boom member in different directions. An adjustable arm is attached to the boom member and can slide in either a forward or reverse direction. A winch assembly is used to supply a cable through pulleys on the adjustable arm to raised or lower a target object. A shock absorber prevents the cable from overstretching. Overall, the patent provides a technical solution for adjusting the position of a boom member and the associated target object.

Problems solved by technology

Moreover, these davits are not adjustable from the positions where they are installed, for example, on the deck of the ship.

However, the disclosed davit system is incapable of extending or retracting the lifting frame to align the lifting frame vertically above target objects placed at different locations on a platform or vessel.
