Understanding about the Differences between Dogging, Rigging, and Lifting

June 29, 2020

Most works and activities that revolve around construction and loading or unloading of freight utilise cranes for various reasons. Cranes generally lift, move, transfer, and lower heavy materials or equipment from one location to another. Since the weight of the involved materials is beyond the lifting capacity of and even more than the average weight of humans, adequate safety measures must be in place to avoid any accidents from happening.

Crane operators and other involved professionals must adhere to several safety operation procedures and other processes to safely conduct lifting activities. Some of the most common processes that revolve around lifting equipment are dogging, rigging, and lifting. These tasks can be extremely dangerous and that they must be conducted by professionals only. Additional risk assessments and other types of safeguards are conducted to ensure a safe work environment.

The following are some things that you need to know about dogging, rigging, and lifting.

Dogging Operations

Dogging operations are typically carried out by licensed dogmen or doggers. The main purpose of dogging is to determine everything that must be considered before the lifting operations begin. For successful lifting works, dogmen must choose and inspect all appropriate slinging gear and components, which include chains, slings, ropes, cables, and hooks. They must also assess the most feasible slinging method and direct the movement of materials whenever they are being lifted. When deciding for all these tasks, dogmen would typically consider the size, shape, mass, and centre of gravity of the load. 

Rigging Operations 

Rigging operations, on the other hand, are conducted by professional and licensed riggers. Some common activities that are covered by rigging include moving, placing, or securing a load through a mechanical load shifting equipment. Rigging also covers the installation, erection, and dismantling cranes or hoists. There are three levels of licenses available for riggers: basic, intermediate, and advanced. Basic rigging works typically involve the erection of precast tilt-up concrete panels and structural steel and the installation of static lines, safety nets, crane loading platforms, and perimeter shutters. Alternatively, intermediate rigging involves the installation of conveyors, dredges, and excavators. Setting up cableways, suspended scaffolds, gin poles, and shear legs are among the tasks covered in advanced rigging.

Lifting Operations

Lifting operations pertain to the actual lifting and lowering of heavy load and materials. Any loading and unloading activities of a crane, forklift truck, or any other lifting equipment at ports and docks are also covered by lifting operations. Licensed operators directly manage the movements made by the crane and any other similar lifting equipment and mechanism. Some common hazards involved in lifting operations include falling loads, failure of lifting equipment, damage to surrounding properties, and accidents. The proper implementation of dogging, rigging, and lifting operations, through the help of licensed and experienced personnel, all contribute to a safe and efficient work environment.
