This load represents a force that is much less than that required to make the lifting equipment fail or yield. The WLL is calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.
Forceful exertions: Carrying or lifting heavy loads; Pressure points: The load applying pressure to select areas on the body only; Static postures: Staying in the same position for extended periods of time [2] Although musculoskeletal disorder can develop overtime, when manual handling of materials, they can also occur after only one activity.
The Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) are set of regulations created under the Health and Safety at Work etc. Act 1974 which came into force in Great Britain on 5 December 1998 [1] and replaced a number of other pieces of legislation which previously covered the use of lifting equipment. [note 1] The purpose of ...
The cumulative driving time without taking a break must not exceed 4.5 hours. Before surpassing 4.5 hours of cumulated driving time, the driver must take a break period of at least 45 minutes. However, this can be split into 2 breaks, the first being at least 15 minutes, and the second being at least 30 minutes in length. The daily driving time ...
[4] 3 Tandem axle by definition. [11] 4 Distances between 8 feet (2.44 m) to 8 feet 11 inches (2.72 m) may not be rounded down. [30] 5 __ Maximum legal weight limit based on number of axles. Increased axle lengths beyond these do not increase maximum legal weight. [11]
In New Zealand, an oversize load is a vehicle and/or load that is wider than 2.55 m (8 ft 4 in) or higher than 4.3 m (14 ft 1 in). Overlength limits vary depending on the type and the configuration of vehicle, but the overall maximum forward distance (i.e. the length from the front of the vehicle to the centre axis of the rear axle set) is 9.5 ...

S = (W x Ksl x Kd) / n = (64.8 x 1.16 x 1.2) / 2 = 45.1 kN load resistance required per anchor; Anchor capacity for site lift F/n = 23 kN per anchor during site lifting (n = 2 lifting anchors) Reference to the load capacity tables provided by the anchor manufacturer is required to make an anchor selection for the specific concrete strengths at ...
