The corresponding types of needs, hooks, and payloads
Engine
Cummins ▪ (Euro Tier III), which can optionally Euro Tier IV;
▪ Power: 447 Kw;
▪ Speed: 1800 rpm;
▪ Maximum torque: 2542 N.m;
▪ At maximum output torque: 1400 rpm.
▪ Load signaling mechanism
The cruise gearbox is controlled by a modified shift hydraulic motor, used to control the main load transport I and the main load transport II to lift and reduce the load. It provides good performance and ensures the rapid lifting power of the main load.
▪ Just one main needs to be able to load under 400t, while for loads over 400t, both need to work. Need I and II can both synchronize.
▪ The maximum number of machine units is 60. The layered coil will ensure the machine does not tangle the wire. The advantage of the gearbox is that it reduces noise, works highly efficiently and is easily accessible to change oil.
Load hooks: 7 types of hooks with a load from 18 tons to 800 tons, suitable for many operating environments
Load capacity: Length 24m (basic) to 111m (with super lift)
▪ Layout: main need 10.5m, transition section 12m; 1 1.5m connector; 1 3m connector; 3 connectors 6m and 6 connectors 12 m
▪ Extension of lifting lift is installed on top of the main need.
Working capacity
SCA8000A has a working load of up to 615t, including a superior structure, a lower structure, a main unit and partnership, a central critical, a 24m base, and an 800t hook.
Counterweight
▪-The SCA8000A’s counterweight consists of barrel-type, rear-facing, ultra-light and specific parameters as follows:
Name | Quantity | Length (m) | Width (m) | Height (m) | Unit Weight (t) |
Body counterweight | 4 | 2.4 | 2.85 | 0.484 | 10 |
Body counterweight tray | 2 | 2.97 | 5.43 | 1.06 | 20 |
Rear counterweight | 20 | 2.4 | 2.85 | 0.484 | 10 |
Rear counterweight tray | 2 | 3 | 2.66 | 2.4 | 15 |
Superlift counterweight | 36 | 2.4 | 2.85 | 0.484 | 10 |
Superlift counterweight tray | 1 | 9.25 | 2.5 | 1.8 | 32 |
Optional rear counterweight tray | 1 | 3.64 | 2.95 | 1.74 | 6.7 |
▪ Including load lifting hydraulic system, tourist hydraulic system, rotating hydraulic system, burst traction hydraulic system, servo hydraulic system, back-stop hydraulic system, cooling system, anth aid hydraulic system. The main hydraulic components are the original parts imported;
▪ Characteristics: Lifting, transmission, explosive and rotating system of closed ring type, with energy saving, high efficiency, fast response, low thermal radiation and long service life; ▪ The control components are proportional to the current to facilitate the precise and intelligent control; ▪ back-stop hydraulic system through the balance valve of the external control, mounted on the cylinder to ensure safety;
▪ Cooling System characterized by high power and faster.
Advantages and applications are mentioned:
The cabin of the machine has a sliding door structure, suitable for crawler cranes and convenient for operators. The SCA8000A is designed with a fully enclosed steel frame structure, and a large-area tempered glass door installed on the front, sides and top helps to transmit more light, making the cabin’s interior space spacious, bright and with wider views. The chassis is equipped with independent transmission equipment.
Planetic gears are controlled by hydraulic transmission engines and independent transmission is carried out through the transmission of steering gears. The moving system has two speeds, which are high speed and low speed: Low speed can provide enough traction to receive 100% movement with load; High speeds can provide higher speeds to improve shipping efficiency.
The chain base is made of materials with high strength and wear resistance through advanced casting. Once installed on the device, its tension can be adjusted through the hydraulic cylinder and the gasket position can be adjusted to achieve ideal tension.
Hydraulic cylinder steering power connects to the wheel frame, easy to assemble and disassemble. Solid steel welding frame structure is passed. The larger body design significantly improves with the stability of the overall crane. The weight is 80t (40t in front and rear), too.
Engineers are assembling and putting into use SANY SCA8000A on the construction of Central Highlands wind power.
