Slinging loads in metal manufacturing. In recent years, a significant number of fatalities and serious injuries in the metal fabrication industries have been caused by poor slinging practices when using overhead travelling cranes to move and lift large non-uniform loads. WorkSafe inspectors have found on occasions welders, boilermakers. Filed Apr. 14, 196i), Ser. No. 22,351 '7 @laims. (Cl. 212-58) This invention relates to devices of the type used in conjunction with rotating or slewing cranes for the purpose of preventing a load depending from the crane from pendulating or swinging back and forth beneath the end of the boom from which it is suspended (c) to prevent the load from slipping over and falling down (d) to keep the centre of gravity of the system outside the body 8. A man is sitting by the side of a large lake. He hears the utterances of bathers with their mouth close to water surface more clearly than if they were at same distance away on land.

Employee. In the past, OSHA Standard 1926.550(b)(2) referred to ANSI Standard B30.5 - 1968 entitled Safety Code for Crawler, Locomotive, and Truck Cranes Section 5.3.3.f under Moving Load which stated that the operation should avoid carrying loads over people

In building construction where concrete is raised by mobile cranes, such loads raised to elevations more than 150 feet shall be deposited or discharged only in hoppers or other appropriate facilities which are so located as to permit operation of the boom of any such crane at a minimum load radius Hoist load brake locked-up (handle works in UP but not DOWN direction). Possible Cause: Load not lowered after hoist was used for lifting. Possible Solution: Unlock load brake. Hoist load brake slips (hoist will not support loads). Possible Cause: (i) Brake friction surfaces coated with oil or friction washers glazed A derrick without a boom. The mast consists of two side members spread farther apart at the base than at the top and tied together at top and bottom by rigid members. The mast is prevented from tipping forward by guys connected to its top. The load is raised and lowered by ropes through a sheave or block secured to the top crosspiece Video Transcript. Hoist is a mechanism use to raise or lower the load. Stop the hoist before the load block is pulled into the hoist drum. The proper selection and use of rigging is equally important to the proper operation of the crane for safely lifting the load. The type of rigging use is determine by object being lifted and its weight Swinging/Slipping Objects. Secure all loads and lift them evenly to prevent them from slipping. PPT-147-01. Loads must be lifted evenly. As the load is being secured, the rigging must be placed to evenly distribute the weight of the load. A load that is lifted unevenly has the potential to slip

tipping/slipping problems, sliding will rarely occur simultaneously at all surfaces on complex problems). On these surfaces, set the friction force equal to their maximum value: f= f max= sN. On all other surfaces, leave the friction forces as general forces of reaction. Consider the following examples of equilibrium problems with friction In building construction where concrete is raised by mobile cranes, such loads raised to elevations more than 150 feet shall be deposited or discharged only in hoppers or other appropriate facilities which are so located as to permit operation of the boom of any such crane at a minimum load radius.

- 7 - Characterize the Load Calculating Weight of Load Step 1: Determine volume • Measure the object to get dimensions (length, width, and height) and determine volume. Volume formulas: • Rectangle/square: Volume = Length x Width x Height • Hollow cylinder: Volume = 3.14 x Length x Wall thickness x (Diameter wall thickness load and spread out to provide stability for longer loads (Figure 24-10). It does not grip the load completely but can balance the load, making it less likely to tip. The load must be lifted horizontally with slings of even length to prevent the load from sliding out. For lossely bundled loads, use a double wrap choker hitch. Double Wrap Choker. Prevent possibility of wire rope slipping out of socket and drop-ping the load! Use only the correct wedge and socket corresponding to the wire rope size being used. See Parts Manual for exact part number of wedge and socket required. Remove all rough edges and burrs from wedge and socket that may cut wire rope or prevent rop (Some mobile cranes cannot operate with outriggers in the traveling position.) Direct workers to always keep hoisting chains and ropes free of kinks or twists and never wrapped around a load. Train workers to attach loads to the load hook by slings, fixtures, and other devices that have the capacity to support the load on the hook Lifting operations. A lifting operation is an operation concerned with the lifting and lowering of a load. A load is the item or items being lifted which could include a person or people. A lifting operation may be performed manually or using lifting equipment. Manual lifting, holding, putting down, carrying or moving is often referred to as.

Insufficiently supported or hastily transported wide loads will similarly 'rock' the truck. Lower your speed, make all driving actions smooth, and carry less than the normal rated capacity. Lower your forks Driving with a raised load makes your truck much less stable, as its centre of gravity becomes dangerously high. Keep your forks and load. The Problem. In 1999, over one million people suffered a slip, trip or falling injury, and over 17,000 Americans died as a result. Of the estimated 3.8 million disabling injuries each year in the work force,15 percent are due to slips, trips, or falls, which account for 12 to 15 percent of all Workers' Compensation costs Bridle hitches. Are made of 2, 3 or 4 single leg hitches. Are used for hoisting an object that has lifting lugs or attachments. Position the hook over the centre of gravity of the load. Adjust sling leg lengths with turnbuckles to level raised load. Check each sling leg angle to ensure sling is not overloaded Keep loads as close to the body as possible and do not twist while lifting, carrying, or setting down a load. Nose, shoulders, hips, and toes should all be facing the same direction. Minimize reaching. As a general rule, bend at the knees, not the hips. Get help when needed

In its basic function, the DCBS is a variable-speed chain hoist based on the proven DCS range. It has a perfect command of the usual tasks of this hoist. The operator actuates the D-Grip Servo control handle, and the load with a maximum weight of 160 kg is raised or lowered by an electric motor. What sets the DCBS apart from other chain hoists. When the box is raised into the air it will tilt until the CoG is underneath the crane hook. This means that if the CoG of a load is known, or can be calculated - the exact angle of tilt can be predicted before the lift. This is critical when planning a lift and determining whether or not the lift will be stable In these cranes the load is suspended from a gripping device by cables, and acts like a pendulum. These swaying loads are a safety hazard and place additional stress on the crane structure. The solution is to control the motion closely using an AC drive on the input to the electric motor keep the reports of any examinations as well as any declarations of conformity or test certificates; make sure the load is properly attached to the lifting equipment. If necessary, securely bind the load to prevent it slipping or falling off; before lifting an unbalanced load, find out its centre of gravity Gantry Girder Sections: Small cranes may consist of an integrated double beam unit. Large cranes consist of a double truss unit. Fig. 11.2 shows the types of beam sections used for gantry girder. These beams are subjected to vertical and horizontal loads due to dead load of the crane, the hook load and dynamic loads

Raise the load a few inches, stop, and check for proper balance and that all items are clear of the path of travel. Never allow anyone to ride on the hood or load. Keep all personnel clear while the load is being raised, moved, or lowered. Crane or hoist operators should watch the load at all times when it is in. Never turn your back on a load. Keep your eye on it until it is a safe distance. Never allow more than one person to control a lift or give signals to a crane or hoist operator except to warn of a hazardous situation. Never raise the load more than necessary, or leave the load suspended in the air. Never allow anyone to work under a suspended load stored in overhead locations to prevent them from falling on people below. Avoid working underneath loads being moved by cranes, backhoes, and hoists. Barricade hazard areas and post warning signs. Use safety glasses, goggles, face shields, etc., where machines or tools may caus If failure of a suspended load could affect the public, erect firm exclusion zones to physically prevent entry into the fall zone. Situational Safety Awareness Finally, working around or near suspended loads requires a great level of situational awareness, whether you are the operator who is lifting and/or carrying the load, or you are working.

determine how to prevent the load from damaging the sling. — The easiest way to do this is to place padding around the sling. To protect both the sling and the load, place wood or other softeners between them. — This will help prevent the sling from cutting into the load. — It also stops the load from causing wear and tear on the sling • Keep the load in the middle, between shoulder and knee height. • Avoid twisting and side bending while lifting. Step or pivot, turning the whole body. • Plan where to set the load down, ideally on a raised platform that won't require bending down with the weight of the load. Ensure workers take advantage of rest periods To move loads safely: † Keep the load centered under the hook. † Do not side load the hook, which can cause the load to swing unexpectedly or overload the crane. † Ensure that ropes, slings, or chains are not twisted together or caught on railings or equipment. —This can cause the load to slip, tip, or rotate system allows all counterweight configurations to be raised and lowered by hydraulic cylinders from the comfort of the operator's cab. Designed with transport in mind Each overflow load weights under 45,000 lbs (20 412 kg) Check Wind Speed on Load Charts (Most Cranes have a Maximum Wind Speed of 9.8 M/P/S) Example Only Mobile cranes are designed with a standard drag factor of 1.2 and a wind area/weight of 1.2 m²/tonne.
