N/LH type double girder bridge crane with hoist trolley is based on double main beams and electric hoist trolley as the lifting mechanism. The working level is M4-M5. Standard capacity from 0.5 ton to 32 tons. N/LH double girder bridge crane is suitable for a variety of occasions, mainly including industrial production, warehousing management, logistics centers and special environment operations.
N/LH type double girder bridge crane with hoist trolley adopts ND/CD/MD type electric hoist trolley or Chain hoist trolley.
N/LH type double girder bridge crane with hoist trolley is mainly suitable for operation, assembly, maintenance and loading and unloading operations in machinery manufacturing workshops, warehouses, material yards, power stations, etc. It can complete various transportation, assembly, maintenance and loading and unloading operations. It can also replace ordinary double-beam bridge cranes and be used in production workshops of the textile industry and the food industry to meet the needs of different industries and customers.
Depending on your actual use, there are different overhead cranes for customers to choose from. We have an experienced team of crane engineers. We design the right bridge crane system for you, and provide a full range of after-sales services to enable your crane to operate quickly, stably and reliably.

Advantages
The advantages of the N/LH type double girder bridge crane with hoist trolley mainly include the following aspects:
High lifting height and large lifting capacity: The double-beam bridge crane combines the characteristics of the general double-beam bridge crane and the single-beam crane, and has a high lifting height and a large lifting capacity.
Strong lifting stability: The double-beam structure provides higher stability for the crane. The hoisting mechanism can be lifted more smoothly with the support of the double beam, reducing the unstable factors caused by uneven load or swing, and is suitable for occasions requiring high-precision operation.
High space utilization: The hoist of the double-beam bridge crane is small and compact, which can maximize the use of space under the lifting mechanism and reduce unnecessary floor space. It is suitable for factories and workshops with limited space.
High structural strength and strong bearing capacity: Compared with the single-beam structure, the double-beam structure provides higher bearing capacity and anti-deformation ability, can support larger loads, and ensure that the equipment maintains good stability in long-term use.
High lifting speed and operating efficiency: Double-beam bridge cranes are usually equipped with multi-speed drive systems, which can achieve more precise and flexible control. The hoist lifting mechanism is easy to operate, which can quickly complete the lifting operation and improve the overall work efficiency.
Easy operation and high degree of automation: Double-beam bridge cranes are usually equipped with modern operating systems, which can be operated by remote control, buttons or automatic control systems, which greatly improves the convenience and safety of operation and is suitable for large-scale production and automated production lines.
Easy maintenance and low operating cost: Due to the relatively simple structure of double-beam bridge cranes and the compact design of hoist lifting mechanisms, the maintenance of the equipment is relatively simple. Reasonable design makes it easy to replace vulnerable parts, and the operation efficiency is high, reducing equipment failures.
The lifting mechanism is an electric hoist trolley, and the crane has light weight, small size and small wheel pressure.
It consists of four parts: box-shaped bridge, trolley running mechanism, hoist trolley and electrical equipment.
It can adopt single speed or stepless speed regulation, with superior performance and meeting production and maintenance requirements.
lower building clearance.
The requirements for the factory building are relatively small.
The control method can adopt pendant control, wireless remote control, cab control, or a combination of the three control methods.
The international standard sandblasting and painting process is adopted. When the crane is fully loaded, the deflection of the main beam is less than 1/800 of the span. The surface of the structure must be shot blasted before painting to reach Sa2.5 level, and epoxy painting must be carried out after painting. At least two coats of epoxy primer must be sprayed after surface treatment.
