1. Product core positioning and design background

The core positioning of LXD type multi-pivot electric single girder suspension crane is to solve the problem of lifting and transportation and infrastructure costs of large-span plant, in view of the conventional suspension cranes in large-span scenes above 10m, easy to appear in a single point of the roof load is too large, the beam deformation and vibration, and need to be raised and strengthened plant resulting in soaring infrastructure costs of the industry pain points, Henan Mining through the multi-pivot decentralized operation of the single girder suspension crane is a cost-effective solution.

Henan Mine Crane is able to adapt to 10m-60m large-span operation scenarios through multi-pivot point load dispersion and lightweight structural design, and at the same time, there is no need to over-reinforce the roof of the factory building, no need to raise the height of the building, which greatly saves the cost of factory building construction and renovation of overseas customers, and it has already become the standard lifting equipment for overseas aviation manufacturing, large-scale heavy industry and other industries.

2. Core structural design

The whole structure of the machine is designed around the core requirements of large span, decentralized load, stable operation, modular assembly structure, the core consists of three key parts, the structure of the synergy to achieve efficient and safe lifting of large-span scenarios:

2.1 Suspension bearing structure: adopting multi-pivot point (multi-rail) suspension design, the number of pivot points can be customized according to the span, and the weight of the whole machine and load will be evenly dispersed to the roof of the plant through multiple suspension points, which greatly reduces the pressure on the roof of a single point.

2.2 Driving and operating mechanism: the standard three-in-one driving system is integrated in the running end beam of each suspension point, which realizes the synchronous start-stop and synchronous operation of all suspension points through precise synchronous control technology, completely avoiding the problems of main beam jamming and deflection caused by unsynchronized pivot points in the large-span operation, and the stability of the operation is far more than that of the conventional driving system;

2.3 Lifting mechanism: equipped with customized electric hoist lifting mechanism, seamless connection with the main beam, according to the lifting needs of different lifting capacity of the optional hoist, with vertical lifting and trolley transverse movement function, flexible operation, suitable for large-span plant in the multi-area lifting needs, the hoist protection level is suitable for the industrial operating environment, can be a long time and stable operation.

3. Core product advantages (fit the needs of overseas super-large-span plant, different from conventional suspension cranes)

As a multi-pivot distributed load suspension crane specially designed for large-span scenarios, its core advantages revolve around large-span adaptability, structural safety, cost savings, and stable operation, which is perfectly suited to the operation and procurement pain points of overseas aerospace manufacturing, large-scale heavy industry and other customers, and is also the core highlights that differentiate it from the conventional electric single girder suspension cranes:

3.1 Multi-pivot point load dispersion, reduce roof pressure, improve structural safety: the core design highlights of multi-pivot point (multi-rail) suspension, through multiple suspension points will be evenly dispersed load, single-point pressure compared to conventional single-pivot suspension cranes reduced by more than 60%, no need to do additional reinforcement of the plant roof, significantly reducing the risk of damage to the roof structure, while the main beam force uniformity, and effectively reduce the deformation and vibration of the beam, the safety of equipment operation and service life significantly reduced. At the same time, the main beam is subjected to uniform force, which effectively reduces the deformation and vibration of the beam, and greatly improves the safety and service life of the equipment;

3.2 Three-in-one drive system, high synchronization of each pivot point, more stable operation: equipped with the industry’s high-end three-in-one drive system, with accurate synchronization control technology, to achieve the complete synchronization of all suspension points, no jamming, no deflection, no jitter, even in the 60m large span, the whole machine is still running smoothly, to completely solve the problem of poor synchronization of the conventional drive system in large-span scenarios, and to enhance the efficiency and safety of the lifting. efficiency and safety;

3.3 Lightweight design, reduce building height, save large amount of plant costs: the machine adopts high-strength lightweight structure design, self-weight is 20% lower than the same span of conventional cranes, and at the same time, the multi-pivot suspension design does not need to additionally raise the height of the main beam mounting, which effectively reduces the building height of the plant, and according to the actual calculations, it can save more than 30% of the cost of construction and renovation of the plant for overseas customers, and it is the cost optimization choice for the large-span plant. It is a cost optimization choice for large-span factory buildings;

3.4 Modular assembly, strong adaptability, customizable fulcrum and span: the whole machine is modular assembly structure, the number of suspension fulcrum, main beam span, lifting weight can be customized according to the actual size of the customer’s plant and lifting needs, from 10m conventional large span to 60m extreme large span can be adapted to the same time, and according to the operating scenarios can be equipped with explosion-proof, dust-proof, and other customized design, to meet the needs of different industries overseas. The product can also be customized according to the operation scenario, such as explosion-proof and dust-proof.
