transport. The attachment will push the slip sheet and load off the forks for placement. Drum Handler – is a mechanical attachment that slides onto the tines (forks). It usually has a spring loaded jaw that grips the top lip edge of a drum for transport. Another type grabs around the drum in a manner similar to the roll or barrel attachments. Man Basket – a lift platform that slides onto the tines (forks) and is meant for hoisting workers. The man basket has railings to keep the person from falling and brackets for attaching a safety harness. Also, a stap or chain is
Сused to attach the man basket to the carriage of the forklift.

б А ДRoad roller
Road roller (sometimes called a roller–compactor, or just roller) is a compactor type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. In some parts of the world, road rollers are still known colloquially as steam Иrollers, regardless of their method of propulsion. This typically only applies to the largest examples (used for road– making). Road rollers use the weight of the vehicle to compress the surface being rolled. Initial compaction of the substrate is done using a pneumatic–tyred roller, with two rows (front and back) of pneumatic tyres. The flexibility of the tyres, with a certain amount of vertical movement of the wheels, enables the roller to operate effectively on uneven ground. The finish is done using metal–drum rollers to ensure a smooth, even result. Rollers are also used in landfill compaction. Such compactors typically have knobbed (sheep s–foot) wheels, and do not achieve a smooth surface. The knobs aid in compression due to the smaller area contacting the ground.

Drum types: |
• drums come in various widths: 24–to–84 inches; |
|
• single–drum sheeps / pad–foot (soil); |
|
• |
single–drum smooth (asphalt); |
|
б |
• double–drum (duplex) sheeps/pad–foot (soil);
• double–drum (duplex) smooth (asphalt);
• 3–wheel cleat with bulldozing blade (landfills).
On some machines, the drums may be filled with water on site to achieve the desired weight. WhenАempty, the lighter machine is easier and cheaper to transport between worksites. Additional compaction may be achieved by vibrating the roller drums. Water lubrication may be provided to the drum surface to avoid hot asphalt (for example) sticking to the drum. Hydraulic transmission permits greater design flexibility (early examples were direct mechanical drive) and reduces the number of moving parts exposed to contamination.ДHuman–propelled rollers may only have a single roller drum. Self–propelled rollers may have two drums, mounted one in front of the other (format known as duplex), or three rolls, or just one, with the back rollers replaced with treaded pneumatic tyres for increased traction.
