crane and loads. • Before lifting, fully extend outriggers and ensure their stability on the ground. • The weight of the load shall not exceed the Safe Working Load. • Never abruptly swing or stop the crane. • Loads shall not be dragged on the ground. • Move the load at a safe speed - use low speeds within several metres of the load's. Lifting equipment Lifting load coefficient f Tower crane and fixed crane 1,2 * Mobile crane 1,4 * Lifting and transporting on flat ground 2 - 2,5 Lifting and transporting on uneven terrain 3 - 4 4 In the precast factory: for de-mould f = for pitch and transport f = On site.
All lifting equipment must be marked with its safe working load (SWL). Lifting equipment must not be used to move loads heavier than the SWL. Lifting equipment must only be used by people who have been trained to do so. Never stand over s suspended load. Look for overhead obstructions such as power cables. Ensure that lifting equipment has no. Basic Slinging & Safe Use of Lifting Equipment. Lifting equipment training. Max Delegates: 12 nr – Course duration: day – Length of certification: 1 year. Summary. The removal of equipment from sites involve the use of lifting equipment to lift and transfer loads, often in restricted areas, which may involve the temporary installation.
The equipment manufacturer’s lift chart designates the safe lifting capacity at various boom angles, lift heights and swing radii. A load can get out of control quickly if lift charts aren’t. a. Webbing slings, wire rope slings and chain slings with a safe working load (SWL) rating greater than kg. b. Load restraint equipment items with rated capacity exceeding kg. Minor Lifting and Load Restraint Equipment items Minor lifting and load restraint equipment items are general rigging and load restraint items that are.

Safe Working Load (SWL) sometimes stated as the Normal Working Load (NWL) is the maximum safe force that a piece of lifting equipment, lifting device or accessory can exert to lift, suspend, or lower, a given mass without fear of breaking.
Usually marked on the equipment by the manufacturer. It is a calculation of the Minimum Breaking Strength (MBS) aka Minimum Breaking Load (MBL) divided by a. The three main parts to any load lifting operation are the lifting equipment (crane/derrick/ hoist), the operator/operation of the equipment, and the rigging of the load.
This guide focuses on the rigging of the load. Specifically, it addresses how mechanical construction. The Safe Working Load is the mass that lifting equipment, usually a wire cable, can safely hold without fear of breaking.
To calculate the SWL, you’ll need to know the diameter of the rope in inches, and apply it to the Safe working loads of lifting tackle. book SWL = D x D x 8. The result is the Safe Working Load in tons. A Pre-Engineered Lift Plan must be completed and submitted to the Lifting Safety Committee chair prior to any work being performed.
The Plan consists of as many drawings, specifications, and procedures as necessary to assess all important load factors and site factors relating to the lift. For further details, consult the Pre-engineered. • The load must be within the capability of the lifting equipment – you will need to calculate the safe working load for the lifting equipment and know how to determine the weight of the load.
• Overload indicators and any other warning devices that form part of the lifting equipment are working correctly and have been tested. In most cases, lifting equipment is also work equipment so the Provision and Use of Work Equipment Regulations (PUWER) will also apply (including inspection and maintenance).
All lifting operations involving lifting equipment must be properly planned by a competent person, appropriately supervised and carried out in a safe manner. a higher safe working load (SWL) than those made in higher tensile steels. As with all lifting equipment, it is vital that the buyer tells the supplier about any particularly hazardous conditions or environmental issues that could compromise the long-term safety of the shackle.
There are many safety considerations for hoists, cranes, and lifting devices. The equipment must be capable of lifting the load.
Because operators may not always have a full view of the work process, it is important to have proper communication during operation. There are numerous situations where workers could be put at risk when a load is in. Safe Working Load (SWL) sometimes stated as the Normal Working Load (NWL) is the mass or force that a piece of lifting equipment, lifting device or accessory can safely use to lift.
Lifting equipment includes any equipment used at work for lifting or lowering loads, including attachments used for anchoring, fixing or supporting it.
The Regulations cover a wide range of equipment including, cranes, forklift trucks, lifts, hoists, mobile elevating work platforms, and vehicle inspection platform hoists. The. The Lifting Operations and Lifting Equipment Regulations (LOLER) are set of regulations created under the Health and Safety at Work etc.
Act which came into force in Great Britain on 5 December and replaced a number of other pieces of legislation which previously covered the use of lifting equipment.
The purpose of the regulations was to reduce the risk of injury from lifting. Lifting equipment is any work equipment for lifting and lowering loads, and includes any accessories used in doing so (such as attachments to support, fix or anchor the equipment).
There are three key terms used in reference to the Regulations: 'lifting equipment';'lifting operations'; and 'the load'. Examples of lifting equipment include: overhead cranes and their supporting runways patient. LO9: Identify the different types of lifting accessories LO Identify the different roles in lifting activities offshore LO Identify the hazards associated with mechanical lifting offshore, including equipment hazards LO Explain the Safe Working Load and colour coding practices LO Identify safe lifting practices.

Safe Lifting Capacity of that sling. If the Tag is not readable or is missing, Do not use it. Inspect sling before each days use, and as often as necessary during the day to assure safety of sling. Sharp edges can slice a sling in two without warning as the load is tensioned.
Use softeners or padding on corners. Describe and state what an ordinary lift and critical lift is. Explain the responsibilities of the Person-ln-Charge (PIC) and designated leader. Explain safe working practices to consider when performing hoisting and rigging.
State the requirements for routine and periodic inspections. State the proper hand signals used during lifting operations. safe working load (SWL): The manufacturer's recommended maximum weight load for a line, rope, crane or any other lifting device or component of a lifting device. The SWL is determined by dividing the minimum breaking strength (MBS) of a component by a safety factor assigned to that type and use of equipment.
The safety factor generally ranges.

Section 6 of the Health and Safety at Work etc Actamended March It outlines the care and safe use of HAND CHAIN BLOCKS and is based on Section 2 of the LEEA Code of Practice for the Safe Use of Lifting Equipment.
It should be read in conjunction with the requirements for lifting. 1. Every lifting appliance shall be tested with a test load which shall exceed the safe working load (SWL) as follows: SWL Test load Up to 20 tonnes 25 per cent in excess 20 to 50 tonnes 5 tonnes in excess Over 50 tonnes 10 per cent in excess 2.Supporting injured workers Working with WorkSafe Information for providers OHS and Cranes and lifting equipment Find health and safety information about using cranes and lifting equipment.
They are also known as plant. Popular topics Previous slide - visual effect.In the case of hydraulic cranes where limitations of pressure make it impossible to lift a test load 25 percent in excess of the safe working load, it will be sufficient to lift the greatest possible load, but in general this should not be less than 10 percent in excess of the safe working load.
