Euro-style Double-Rail Crab Overhead Crane

Parameters

• Design Standards: Compliant with FEM, DIN, and ISO standards

• Lifting Capacity: 1 ton to 160 tons

• Span Length: Up to 40 meters

• Lifting Speed: 0–10 m/min (Variable Frequency Drive) or customized to application needs

• Cross Travel Speed: 0–60 m/min (VFD-controlled)

• Long Travel Speed: 0–120 m/min (VFD-controlled)

• Duty Classification: FEM 2m / ISO A5 to FEM 4m / ISO A7 (Medium to heavy-duty operations)

Features:

• Material:

  • The main beam structure uses Q355B material which is higher than Q235B material.

• Structural design: 

  • First, design a reasonable main beam structure type and pass the calculation of relevant standards, then use finite element analysis software to simulate and verify the strength of the crane, and finally pass type testing to verify the reliability of the crane.

• Simplified accessories: 

  • Customer customization is supported. The crane's additional devices and component types can be customized according to the customer's use environment and requirements.

  • Additional devices include: cab, maintenance platform, maintenance cage

  • Components include: motor, reducer, wheel, drum, wire rope, trolley structure, trolley power supply system, etc.

• Light Self-weight:

  • Reduce construction costs

  • Light weight can reduce the material weight of the product

  • Can reduce the model of the track

  • Can reduce the material weight of the traveling beam

  • Can reduce the material usage of the workshop's load-bearing beam

  • Reduce operating costs​

  • Light weight can reduce the power of the product during operation

  • Can reduce the type of track

  • Can reduce the weight of the material of the traveling beam

  • Can reduce the material usage of the load-bearing beam in the workshop

• Advanced welding:

  • The steel plate material is Q355-B

  • The vertical deflection is L/1000;

  • All steel plates are pre-treated with shot blasting to meet the Sa2.5 standard;

  • The steel is carefully inspected and cleaned before welding, and welding is usually performed by an automatic welding machine (MIG or semi-automatic welding);

  • All welds are subjected to radiographic non-destructive testing; The crane support surface is primed and topcoated within 8 hours of sandblasting, and the paint film thickness is not less than 120μm.

Hoist System:

• Compact structure, light weight, small wheel pressure, maximum space utilization, high comprehensive cost performance, leading technology ensures the optimal limit size of the product, effectively increases the lifting height. Selected high-quality components, low noise, safe and reliable, long service life. High-quality high-quality components are the basis of excellent quality. From lifting motor to reducer, from drum to wire rope, from safe and reliable electrical components to refined structural parts, precise positioning, operation monitoring, easy maintenance, modular design, low maintenance cost, with complete spare parts service.

• ​Parallel shaft helical gear reducers consist of two or three helical gears, and depending on the reduction ratio, the torque range is from 3 to 22500 N M. The transmission ratio range of parallel shaft helical gear reducers is finely graded from 1=3.77 to 1=31434, which can achieve extremely low output speeds and transmit maximum torque. Whether it is lifting drive or running drive, parallel shafts are able to meet the torque requirements of various mechanisms.
