Precast box girders are delivered to the back of the PFS Launcher on a tyre trolley which travels on the previously constructed deck.

Features:

PFS Launchers can install two precast beams per day depending on the distance from the precast yard to the launcher.

Q: Classification of rollers: The front wheel frame is hinged with the frame to reduce the unusual body sway of the road surface. The rear wheel and the frame are rigidly connected. Hydraulic control, hydraulic cylinder control steering. The front and rear grinding wheels are equipped with scraper to remove the adhesive on the roller. A sprinkler system is also provided for compacting the asphalt pavement by sprinkling the wheel to prevent adhesion of the asphalt mixture. To increase the force, but also in the grinding wheel with iron, sand, water and so on, increase the weight. The main technical parameters of steel wheeled roller are weight and line pressure. In 80s, all kinds of steel wheeled roller, machine weight range is about two wheeled roller 2~13 tons, three wheeled roller 1~15 tons, according to the requirements can be pressurized 1~3 tons, three axle roller press 13~14 tons, the pressure is 18~19 tons after weight. The roller is made of pneumatic tyres, usually with 3~5 front wheels and 4~6 rear wheels.

Q: This question asks for a comparison between manual and automatic lifting systems used in construction equipment, highlighting their distinct features and operational differences.: <p>Manual lifting systems in construction equipment rely on human effort to lift and move materials. They are often less expensive, require less maintenance, and are suitable for lighter loads or smaller-scale projects. However, they are labor-intensive, can be slower, and pose higher risks of injury due to the physical demands. Automatic lifting systems, on the other hand, use mechanical or electronic means to lift and move materials. They are more efficient, can handle heavier loads, and reduce the risk of injury by minimizing manual handling. These systems are often more expensive and require regular maintenance but offer precision, speed, and ease of operation, making them ideal for large-scale construction projects.</p>

Q: I heard this snippet of classical music which I can't find now. I've heard it before in movies going back a long, long time so it is quite old I think. I evokes a dark and disturbing image of an army of automatons marching, or maybe a factory with heavy machines with giant piston punching out parts along a never ending conveyer. I think it is cello's, if that helps at all -- I don't have an ear for classical music. I think the announcer said something about tchaikovsky or romeo and juliet but I could be wrong, this doesn't sound romantic in the least, just the opposite; cold and impersonal.: Prokofiev died at the age of 61 on 5 March 1953: the day Stalin's death was announced. He had lived near Red Square, and for three days the throngs gathered to mourn Stalin, making it impossible to carry Prokofiev's body out for the funeral service at the headquarters of the Soviet Composer's Union. Paper flowers and a taped recording of the funeral march from Romeo and Juliet had to be used, as all real flowers and musicians were reserved for Stalin's funeral.

Q: What measures should be taken to ensure safety when operating electric-motor powered building hoists?: <p>When using electric-motor type building hoists, safety precautions include: ensuring all safety devices are in good working order, regularly inspecting and maintaining the hoist, following the manufacturer's guidelines, never overloading the hoist, keeping the hoist and its surroundings clean and free from obstructions, using proper lifting techniques, ensuring the hoist is stable and secure, wearing appropriate personal protective equipment, and training operators on the safe use of the hoist. Adhering to these precautions can significantly reduce the risk of accidents and ensure the safety of workers and the integrity of the construction process.</p>

Q: Surely children don't operate heavy machinery?: Ever heard of child labor? And also the child might be at his/her mom's/dad's work place that has heavy meachinery. Otherwise I would just guess it is there because they don't want to get sued.

Q: Similarities in theme with Emily Dickinson and Stephen Crane?: ?

Q: He is one of my favorite poets. I want to read more of his work.: How about my favorite poem about Hart Crane? AT HART CRANE’S TOMB by Glenn Robert Swetman In his mind’s dark, he spoke a frivolous age where marriage of the like was spring, where vitelline worlds of virgin instinct were crushed in the obscene cleanliness of a raccoon’s paw. Did he imagine that his great sun could come trailing yellow handkerchiefs of light, like a queer comet? No, there is something out there that commands, and not worlds of perfect clipping will turn these rotund hedges into maypoles—and live. That’s why the green expands as it reaches. He must have seen this finally. His leap Into the green sea was, aesthetically, clean.

Q: We found this little shed right outside Virginia City, NV.Inside was this old machinery.. it was probably used for mining.: Yep, it looks like a winch to me too. I see a second drum, so perhaps it was a winch that could pull a cable in two directions, with the cable looped around a pulley at some distant point and being wound onto one of the drums as it is unwound from the other. (hard to see the gearing, etc., from that image). As for age, that electric motor looks like it's about 100 years old! (just a wild guess, of course)
