Lift and dump capacities of hydraulic hooklift hoists typically range from 8,000 to 68,000 lb (3,630 to 30,800 kg). Generally a hoist is capable of lifting (off the ground) and dumping (onto the ground) the same maximum capacity, although there can be exceptions where short wheel bases are involved.
The factor can be as high as 10:1 or 10 to 1, if the equipment poses a risk to a person's life. Working Load Limit (WLL) is the maximum working load designed by the manufacturer. 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 ...
M1977A0 Common Bridge Transporter (CBT). M1977A2 CBT. The M1120 HEMTT LHS (L oad H andling S ystem) is a M977 Heavy Expanded Mobility Tactical Truck with a load handling system in place of a flat bed/cargo body. The HEMTT is an eight-wheel drive, diesel-powered, tactical truck used by the US military and others.
The mechanical advantage is 2, requiring a force of only 50 N to lift the load. A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. The mechanical advantage of a ...
Dragline excavator. Built by Bucyrus-Erie in 1969, Big Muskie was the world's largest ever dragline, being 487 ft (148 m) in length, weighing some 13,500 short tons (12,247 t), and hoisting a 220 cu yd (168.2 m 3) bucket that could move 325 short tons (295 t) of material at a pass. A dragline excavator is a heavy-duty excavator used in civil ...
In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid. TDH is expressed as the total equivalent height that a fluid is to be pumped, taking into account friction losses in the pipe. where: Static lift is the difference in elevation between the suction point and the discharge point.
A modern container crane capable of lifting two 20-foot (6.1 m) long containers at once (end to end) under the telescopic spreader will generally have a rated lifting capacity of 65 tonnes. Some new cranes have a 120-tonne load capacity, enabling them to lift up to four 20-foot (6.1 m) or two 40-foot (12 m) containers.
A windlass is a machine used on ships that is used to let-out and heave-up equipment such as a ship's anchor or a fishing trawl. On some ships, it may be located in a specific room called the windlass room. An anchor windlass is a machine that restrains and manipulates the anchor chain on a boat, allowing the anchor to be raised and lowered by ...
