www.safetygoodwe.com Chapter:- Rigging & Hoisting Material Hoisting - Mobile Crane A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy materials and transporting them to other places. In job sites cranes are commonly employed for the movement of materials. Many incidents were reported while using Hydra type cranes as the stability is less during operations. Below are some safety tips related to crane operations. Cranes are to be operated only by qualified and trained personnel. All equipment used shall have test certificates & in good condition (Crane, Forklift, etc.) Site in-charge / Engineer must inspect the crane visually before use. Ensure that crane is on a firm/stable surface and level & outriggers are fully extended. Workers must not ride on a load or hook. Barricade the working a...

www.safetygoodwe.com Chapter:- Rigging & Hoisting Importance of Web Sling Inspection Hoisting and rigging is a vital and common work task in many workplaces. Slings are devices used to lift and move items mechanically. At times, they can be put under great stress which can lead to damage. This safety talk identifies common sling failures and covers best practices when inspecting these devices to ensure a safe working experience. Common Web Sling Failures Slings can break apart when overloaded. Slings can stretch and fray over time. Slings exposed to cutting and grinding, along with welding splatter, can become burned and compromised. Slings exposed to chemicals can deteriorate. Slings that are continually wet or left in direct sunlight for extended periods can rot and disintegrate.  Inspection of Web slings  Slings should be inspected for burnt marks and unraveled threads. When inspecting slings, if red nylon fibers are visible, the sling shou...

www.safetygoodwe.com Chapter:- Rigging & Hoisting Powered Winches Machines and Accosiated Hazards  At Construction sites uses of  Powered Winch Machine are common, These are basically machines that pull fibre or wire rope. They are often described as boomless cranes. Advantages of using winch machine instead of cranes can include: Lower operating costs The equipment is lighter and more portable The smaller size permits use in tight spots—they’re ideal for use inside buildings. Winch machine can be used for both hoisting (vertical lift) and hauling (horizontal or vertical incline pulls). They may be powered hydraulically, electrically, by compressed air or by an internal combustion engine. The most common winch seen in construction are electric winches (for light lifting and pulling), and air-powered winches (for heavier loads). Wire rope is used for heavy applications while fibre rope is used for lighter applications. Examples of winch use in construct...

www.safetygoodwe.com Chapter:- Rigging & Hoisting Rigging Hardware & Its Failure       Explain dangers: Rigging is only as strong as its weakest link. Workers’ lives depend on the strength of that link. It doesn’t matter what safe working load is stamped on a hook if the hook is cracked and twisted or opening up at the throat. It can’t deliver its full rated capacity. Inspection is vital in rigging and hoisting. Identify controls: Rigging hardware must have enough capacity for the job. Only load - rated hardware of forged alloy steel should be used for hoisting. Load - rated hardware is stamped with its working load limit or WLL. Adequate capacity is the first thing to look for in rigging hardware. For hoisting, the design factor must be 5 to 1. Once the right hardware has been chosen for a job, it has to be inspected regularly as long as it’s in service. There are warning signs that hardware has been weakened in use and should be re...

www.safetygoodwe.com Chapter:- Rigging & Hoisting Rigging Safety Rules & Tips Co mmon Rigging Safety Rules will help you remember some of the most important safe rigging practices. Be sure to establish the weight of the load. Determine the proper type of hitch based on the type of load. Understand the relationships between angles and tension as they pertain to slings and hardware. If you don’t understand the relationships, or if you have any questions, check with your supervisor before you proceed. Make sure that you select the right sling for the job based on the type of load to be lifted. Also, select the right hardware based on the type of load and the type of sling or slings that will be used for the lift. Inspect each sling before you use it. Never use a defective sling. Take defective slings out of service immediately and follow your company’s procedure for handling defective equipment. Inspect all rigging hardware before you use it. Never use defec...

www.safetygoodwe.com Chapter:- Rigging & Hoisting Rigging - Fiber Ropes, Knots and Hitches Fiber rope is a commonly used tool which has many applications in daily hoisting and rigging operations. Readily available in a wide variety of synthetic and natural fiber materials, these ropes may be used as:- Slings for hoisting materials. Hand lines for lifting light loads. Taglines for helping to guide and control loads. There are countless situations where the rigger will be required to tie a safe and reliable knot or hitch in a fiber rope as part of the rigging operation. Fastening a hook, making eyes for slings, and tying on a tagline are a few of these situations. This section addresses the correct selection, inspection, and use of fiber rope for hoisting and rigging operations. It also explains how to tie several knots and hitches. Characteristics: The fibers in these ropes are either natural or synthetic.Natural fiber ropes should ...

www.safetygoodwe.com Chapter:- Rigging & Hoisting Inspection Of Material Hoisitng Slings Slings Sling: An assembly which connects the load to the material handling (lifting) equipment. Types of Slings: Chain Sling Wire Rope Sling Synthetic Web Sling Frequency of Sling Inspections All slings are to be inspected each day prior to their use. This includes chain, wire rope and synthetic slings and their attachments, i.e. master links, clips, hooks etc. At least once in every 12 months depends on the state requirement, third party inspection & certification to be carried out.  Sling Load Capacity and Sling Angles The load capacity of the sling is determined by its weakest component. Never overload a sling. Remember, wider the sling legs are spread apart, less the sling can lift !!!.   Chain Sling Inspection Cracks, stretches, severe nicks, gouges, welding splattered or deformed master links, coupling links, chain...
