This guide provides tips on how to use davit arm systems and top reasons why you should use davit arms and bases on your worksite.
Davit arms and bases are a common sight on most construction projects in Australiaand are used to do a number of transporting, lifting and safety operations. Because of this specialized function, it is very important to ensure that your davit arms function correctly whenever you use them.
Uses of davit arms
Davit arms are mechanical devices used to lower and raise loads. They may be manufactured of wood or steel and consists of a moveable arm that is attached to a support pillar. The arm is connected to a winch that does the actual lowering and raising.
Davit arms are typically used in pairs and can either be mounted to a fixed base or to a portable base. Arms that are mounted permanently to a fixed base can lift heavier things while portable arms are often used for higher applications. The arms can be designed to pivot and may be attached to a track that allows a limited movement range. Because of the ability to lift, lower and rotate, davit arms are very practical when it comes to transporting a load over something such as the side of a ship or boat.
Davit arms were developed for use in marine applications. They are used to lower or raise anchors or lifeboats from ships. Davits also raise and lower boats from water to unload or load cargo. Davit arm systems also have a lot of other uses in construction such as lowering and raising scaffolding platforms, moving constructions materials and so on. Portable arms can be used to rescue injured or trapped persons from wells, large tanks, construction trenches and many other confined spaces.
Davit arms are used to lift a specific amount of weight. When you attempt to overload a davit system or fail to maintain the moving parts of the system, it can cause catastrophic failure. Regular maintenance and repair of construction davit arms should be done for the following reasons.
Lost money and time
A davit arm failure can destroy a portion of the project that has been completed. Materials can be damaged by dropping from the arm while being moved. Work stoppages to fix a davit arm or fix damage caused by a failed arm result in lost work time and money.
A davit arm is often used to lower and raise employees to their work location. Some employees do their job while working in a cage or they may work on a platform supported by a davit. Failure of a davit arm used to carry a person could injure an employee. People working near or under a failed davit system can also be injured by a falling platform.
Davit arms and bases that don’t operate properly can do a lot of damage and injure employees. It can also generate liability for the contractor if private property is damaged or if someone is injured due to the failure of a davit arm. It is critical that all equipment on a construction project work properly to prevent expenses, delays, serious injuries or death.
