Product Description:

1. Performance parameters of D800-42: performance parameters and technical indexes reach both domestic and international advanced level.
• Max. jib length: 80m; Jib length under different assembling modes can decrease progressively by 10 meters and the Min. jib length is 30 meters.
• Max. lifting capacity 42t;
• Max. hoisting capacity at jib tip: 18.6t;
• Max. lifting moment 8000 t.m;
• Max. free-standing height: 75m; Max. working height of anchored crane: 257.4m;
• Hoisting mechanism: QPL4272; power: 132 kW; rope capacity: 1050m;
• Slewing mechanism: HVV145.B1.130C; HVV145.B2.130C, power: 4×145N.m
• Trolleying mechanism: BP185; power: 18.5 kW.

2. Electrical control system
With PLC control, the electrical control system enjoys better reliability and safety. Produced by professional manufacturers with advanced foreign technology, the electrical elements feature service lives that are 3 or 4 times longer than that of domestic products, less faults, easy maintenance and repair as well as reliable operation.

3. Technical features
• The crane boasts of multiple operation modes and wide application;
• The complete machine adopts internationally well-received beautiful shape;
• The crane features high working speed and excellent speed regulation performance. Stepless speed regulation by frequency control, the world's most advanced solution, is adopted for the trolleying mechanism and slewing mechanism, thus ensuring more stable and reliable operation ;
• The cab is independently installed externally with good vision and large inner space, thus offering a good working environment for operators;
• A variety of safety devices are equipped, which are all mechanical or mechatronic products that are applicable to severe working conditions, so as to ensure the tower crane's reliable operation.

Q:When should a crane be load tested?
if crane using regularly more then 8 hrs test should be every 4 months 8 months and full sevice at 12 months............ Load Testing Services ACECO provides inhouse vertical load testing services for load bearing equipment. Examples of equipment that can be load tested: • Below the hook lifting devices • Hoists • Hooks • Testing can be performed to meet ASME B30.20, B30.10, and B30.16 as well as ANSI N14.6. • Standard inhouse 50 ton load testing capacity. • Ability to test higher load capacity devices (Up to 5,000,000 pounds). • Have tested up to 640,000 pounds (320 tons). • Engineering manufacturing available to provide lift fixtures for test purposes. • Can provide nondestructive testing of critical welds and critical locations. • Inhouse capability to make weld repairs using AWS D1.1 qualified procedures and welders. • Calibrated test weights available. • Testing can be performed in accordance with 10CFR50,Appendix B Quality Program. • Certificates of Test and/or Test Reports can be provided. • Can provide onsite load testing services, including supply of calibrated weights.

Q:What is the improvement of Overhead Crane in Shipbuilding?
Hello, 1. Modularity: You can build ships (larger ships) in modular sections and have the crane lift these modular sections and put them into place for final assembly. This is one major advantage that was not available back in the day
Q:I saw da construction of the upcoming tallest building in da world in Dubai,how did da crane get on top of it?
Why do you write da instead of the? It's irritating. I apologize to you. That was rude and unkind of me.
Q:CAB BE CRANE BOOM EXTENDED AT 0 DEEGREE BOOM ANGLE?
The answer is yes. The amount of the lift weight depends on the weight of the counter weights on the back of the crane. There is an indicator (printed or electronic) which indicates the maximum lift based on angle and extension. TexMav
Q:When inspecting a crane, which of the following does not need to be inspected?
Load capacity is not required to inspect provided that the crane was inspected by third party and certified to the loads
Q:What are the parts of a tower crane? What are their main functions?
Jacking frame: placing slewing mechanism, when lifting tower top, bearing the weight of tower crane balance arm, main arm and tower cap.Standard section: support the weight of tower crane itself and lift the weight of heavy load, and resist the overturning moment of tower crane.Institutions include the followingLifting mechanism: lifting heavy objects.Luffing mechanism: lifting the car to change the rotation center distance.: the upper part of the slewing mechanism of tower crane (including the main arm and balance arm and tower cap) around the rotation center of rotation.Lifting mechanism: tower crane lifting, the upper part of the tower crane elevated hydraulic power system.Walking mechanism: the crane can walk on the track.OtherDrivers’ RoomElectric boxLinkage tableA foundation bearing platform or trackOther safety devices
Q:Is making 1000 cranes a good gift to give to my friend?
One idea would be to send one crane that you've made using airmail paper. Write your wish for your friend tell him that you have 999 more cranes waiting for him to return home again.
Q:airsoft gun crane stock to full stock switcharoo?
Ok, I can help. The first step is to take the crane stock off. To do so, extend the stock fully. Then, take the tab you use to extend it, and instead of pushing up to extend it, pull it down and slide the stock off. It make take some force. Be careful of any wires and that you don't break them! Next: take the buffer tube out. Take a long phillips head screw driver and stick it down the shaft. Remove the screw. The whole tube should come out. Don't lose the screw! Next: Install your stock. Next: Screw the screw back in to secure the stock. Done! Make sure the wires are still ok and that they are not pinched!
