the new file is uploaded As the Mk1a version.Ģ:53pm 1-Apr-15: Impossible Innovations mod is required in order to use this craft.ġ0:47am 4-Apr-15: I have upgraded the craft and will upload it today.Ģ:18pm 6-Apr-15: I have uploaded the latest version of the Mk1 series. Adding boosters will increase the Orbit height.

The Max weight is over 100,000kg but, you can only get into an 80km Orbit with that much weight. Also, i have concluded testing the Max Lift capabilities. I have added lights and more RCS Thrusters to the Vessel. Roll to roll (good for slow turns) - YAW to rotate. TRIM up for lift (20 takeoff unloaded, 50 loaded).
#How much weight can a sky crane lift plus
It can detach and take-off again to leave the rover behind safely.Ĭopyright (c)2015, Sky Crane Industries, Inc. Sky Crane - lift over 20,000 lbs plus (20K lbs container provided). The Skycrane Mk1 is used for taking Heavy rovers' into orbit and land at there intended location. TWR: 8.26 (By itself only!) This will change when adding a load. Empty weight: 19,234 lb (8,724 kg) Max takeoff weight: 42,000 lb (19,051 kg) Powerplant: 2 × Pratt & Whitney JFTD12-4A (T73-P-1) turboshaft engines, 4,500 shp (3,400 kW) each Main rotor diameter: 72 ft 0 in (21.95 m) Main rotor area: 4,070 sq ft (378 m 2) Performance.Using the scientific principles behind simple machines, such as the lever and the pulley, cranes can multiply smaller forces to lift heavy loads to great heights. There is a second variant of the vehicle which is the version with the Subway Car attached to it. As heard on the police scanner, the Skylift is manufactured by HVY. This helps it multiply its force to lift heavy objects. The marking 'Liberty Sky-Lift' might be a parody of 'Erickson Air-Crane', the manufacturer and main operator of the S-64, suggesting it might be the operator of the Skylift. Tower cranes often have more than one pulley. Cranes also make use of the pulley, another simple machine. In this way, the crane’s beam acts as a simple lever. This allows it to lift heavy objects with a relatively small force. In balance-style cranes, the crane’s beam is balanced at a point, called the fulcrum. Finally, the operator cab contains the electronic controls used to operate the crane.Ĭranes combine simple machines to lift extremely heavy objects. Initial work on the Sikorsky 'sky-crane' helicopters began in 1958 with the piston-engined Sikorsky S-60. It is named after Tarhe (whose nickname was 'The Crane'), an 18th-century chief of the Wyandot Indian tribe. It contains the crane’s motors, along with large concrete counterweights that help balance the load. The Sikorsky CH-54 Tarhe is a twin-engine heavy-lift helicopter designed by Sikorsky Aircraft for the United States Army. The machinery arm is shorter than the jib. The jib uses a trolley to help carry the load. You’ll also find the working arm, machinery arm, and operator cab. For example, the mast of a tower crane is usually bolted to a large concrete pad that can weigh as much as 400,000 pounds!Īt the top of the mast, you’ll find a gear and motor that allow the crane to rotate. Capacity at Maximum Lift Height 4,000 lb (1,814 kg) Capacity at Maximum Forward Reach 3,000 lb (1,361 kg) Frame Leveling 10 degrees Lift Speed (boom retracted) Up: 15 sec Down: 11.5 sec Boom Speed Extend: 15.7 sec Retract: 15.5 sec Travel Speed Forward 4-Speed: 20 mph (32 kmph) Drawbar Pull 29,570 lb (13,413 kg) Operating Weight With Carriage. To do so, it must be supported by a large, heavy base. It looks kind of like the mast on a ship! But instead of a flag or sail, this mast raises building materials. The tall part of the crane that sticks up in the air is called the mast. Instead, they load these objects onto a crane and carefully put them in place. Concrete and steel beams are much too heavy for construction workers to carry up stairs. Without them, it would be very difficult to lift heavy construction materials and equipment. Tower cranes stay in one place and lift large loads to great heights. Visit a site where they’re building a tall tower, and you’d be most likely to find a tower crane. But how do they work?Ĭranes can be found at construction sites around the world. In many large cities, cranes are as much a part of the skyline as tall buildings themselves. These tall machines are used to lift all those heavy building parts high into the air. If you’ve ever seen a building being built, you know it’s done with a crane. How do they get all those building materials so far up? Have you ever WONDERed how people build such tall structures? Think about how high up they have to move heavy beams and huge panes of glass. Was it the Empire State Building? The Washington Monument? Maybe it was the Shanghai Tower. Think of the tallest building you’ve ever seen.
