Moving loads

More than a third of over-three-day injuries reported each year are associated with manual handling. Manual handling is defined as the transporting or supporting of loads by hand or bodily force, i.e. human effort as opposed to mechanical handling such as a crane or fork-lift truck. Introducing mechanical assistance, e.g. a sack truck, may reduce but not eliminate manual handling since human effort is still required to move, steady or position the load. 

The load may be moved or supported by the hands or any other part of the body, e.g. the shoulders. 

Common injuries are sprains or strains often to the back which arise from incorrect application and/or prolonged use of body force though hands, arms and feet are also vulnerable. Some of these injuries can result in what are known as musculoskeletal disorders or MSDs which can affect the body s muscles, joints, tendons, ligaments and nerves. Typically MSDs affect the back, neck, shoulders and upper limbs. Health problems range from discomfort, minor aches and pains to more serious medical problems. 

The Regulations require that where there is the possibility of risk to employees from the manual handling of loads, the employer should take the following measures, in this order  

avoid the need for hazardous manual handling so far as is reasonably practicable  

It is now widely accepted that an ergonomic approach will remove or reduce the risk of manual handling injury. Ergonomics can be described as fitting the job to the person rather than the

On-Site Handling On-site handhng refers to the activities associated with the handling of sohd wastes until they are placed in the containers used for storage before collection. Depending on the type of collection service, handhng may also be required to move loaded containers to the collec tion point and to return the empty containers to the point where they are stored between cohections. 

By hooking up two regular trailers to one tractor, motor carriers can now move loads up to 127,000 pounds over the New York Thruway and Massachusetts Turnpike. Wnen this double unit returns to the regular highways, it is broken up into two single-trailer units... 

Load Shifting - A load management objective that moves loads from on-peak periods to off-peak periods. 

Consider next the case where trucks are used for moving loads from one point to other point(s). Given the throughput requirement (i.e., the number of loads that must be moved per time unit), and the layout/configuration of the points served by the trucks, we would like to know how many trucks are needed. It is assumed that one load is moved on each trip. 

TroUey conveyors, which are often used for moving loads overhead, are very similar to tow-line conveyors. A chain is placed inside an overhead track, which may be 1-shaped or U-shaped. The carriers are attached to the chain via trolleys. When the chain is powered, the carriers move forward. Based on the product/part being handled, there is a wide range of designs used for the carrier, or... 

From the illustrations it will be seen that the cryostat, being mounted directly on the moving load screw, will move up and down at 25 cps. This and the load-carrying wall configuration dictated the heavy-walled construction. The upper load screw moves only when the load-maintaining system operates. 

Monorail High capacity load blocks suspended from trolleys which traverse monorail beams suspended from boiler support steel. Provides capability to lift and move loads within boiler cavity. 400 (363)... 

Load and impact factors must be used for moving loads. It is recommended that a 25% impact factor and a minimum load factor of 1.5 be used. The combined load and impact factor should be 1.5-2.0. 

Typically, rapid repair of main cracks in slabs is realized using bituminous masses covering only the damages. Unfortunately, this kind of protection is ineffective just after few months of exploitation, because the degraded mass (Fig. 2b, 2c) allows for infiltration of water under slabs [8]. The coming into being hydrodynamic pump effect (due to moving loads - Fig. 3a) destructs sealants in joints (Fig. 3b) and causes uneven settlement of concrete slabs (Fig. 3c). The solution of this problem is the use of special polymer flexible joints.

Hand signals, when moving loads, must he precise, simple, expansive, easy to make and to understand and clearly distinct from other such signals. 

New chapters have heen added to cover Standards, measurement and gauging as well as Moving loads and Drawing specifications and data. 

The wheel-tracking test was developed for the determination of asphalt susceptibility to deformation under moving load simulating conditions that exist on the road. The tests are all described in CEN EN 12697-22 (2007).

Tire engineering is the study of the stresses created within a tire and includes such factors as straining of components while the tire is being built, the tire stresses while mounted on a wheel of a moving loaded vehicle, quantification of such stresses, and minimization of such stresses through effective distribution of load and proper selection of materials. Consequently, tire tech-...

Take special care when moving loads wrapped in grease or bubble-wrap. Never move a load over other people or walk under a suspended load.
