Underhung Cranes Introduction

The underhung overhead crane can increase efficiency by reducing the time and effort required to move materials around the factory floor. With an underhung crane, operators can control the crane from a safe distance, reducing the need to walk back and forth between the control panel and the crane. This speeds up material handling, increases productivity and reduces downtime. underhung overhead cranes increase the flexibility of material handling operations. The crane can be moved to different areas of the factory floor, allowing for more efficient and flexible use of the crane. Unlike traditional overhead cranes that run on top of the runway beams, underhung cranes are suspended from the runway beams, allowing them to operate in areas with limited headroom.

Underhung overhead cranes are widely used in the automotive industry, food and beverage industry, warehouse and storage facility industry, textile industry, printing industry, etc. underhung bridge cranes are a game changer for material handling operations in areas with limited headroom. Their reduced headroom requirements, improved efficiency and increased flexibility make them the ideal solution for a wide range of industrial applications. With the ability to operate in areas where conventional overhead cranes cannot, underhung cranes offer a cost-effective solution to many material handling challenges. As technology continues to advance, we can expect to see more innovative material handling solutions in the future.

Overhead Crane Features

Design

Technology

Production

Maintenance and Security

Overhead crane systems are designed in accordance with ISO, FEM and DIN standards.

Customized according to the lifting weight required by the customer's project, the operating speed of the electric hoist and the working level.

The steel plate material is general-purpose steel Q235B, and the steel plate will be pretreated by shot blasting to reach the standardization of Sa2.5 level.

Design Scheme

SEVENCRANE stands for first-rate service, cost-effective, high quality.

The main beam and end beam are connected by high-strength bolts to ensure the accuracy and smooth operation of the whole machine.

A variable structure control scheme, a variable structure controller combined with a state feedback control scheme and an integrated control scheme are proposed to control the bridge crane.

We have a professional team of engineers to design and develop cranes, and have a complete technical system to analyze crane design drawings.

Our bridge crane component design and structure standards are certified according to DIN15018, BLATT2 and the steel structure welding standards are in accordance with DIN18800, BLATT7.

Equipped with a double-speed lifting mechanism, the running mechanisms of large and small vehicles all adopt frequency conversion stepless speed regulation.

All the plates are automatically cut by CNC cutting machine, and the camber of the main beam is preset to avoid the problem of deflection of the camber of the traditional fire-baked main beam.

The steel surface is treated with shot blasting and sand blasting to improve the adhesion of the paint and prevent the paint from peeling off, ensuring the long-term beauty of the whole machine.

Technology

The main welding seam adopts submerged arc automatic welding, non-destructive flaw detection, and the shape is beautiful to ensure the welding quality.

End beam material: high quality alloy steel Q345B.

The end beam is welded and formed by rectangular steel pipe or steel plate, and the formed end beam is positioned and processed on a CNC boring and milling machine at one time to ensure dimensional accuracy and fit tolerance.

The lifting trolley has a modular design, and the working level is FEM M4-M6. The entire lifting trolley has a compact structure, low headroom and light weight.

Production

SEVENCRANE stands for first-rate service, cost-effective, high quality.

The main girder of the crane is welded by steel plates, and the steel plate materials meet the international crane production standards. The main steel structure materials we use are not lower than Q235B, and the materials used have material reports and corresponding qualification certificates.

There are buffer blocks at both ends of the end beam to reduce the impact force of the collision and reduce the impact inertia. The beam body of the whole machine adopts shot blasting and painting process according to the world standard.

The running track of the trolley is made of square steel to increase the effective contact area of the wheel tread and reduce the weight of the track. The material of the square steel track is Q345B.

The operation room is operated by a linkage table, and is equipped with a remote control at the same time. Through the switch, it can be operated by remote control or switched between operations during operation. Lighting and seats are installed indoors, and the entrance of the operating room is end-entry, which conforms to European and international standards.

Our crane design concept is an extension of the European concept, and we have summarized our unique production technology and solutions through long-term in-depth research and application practice.

MAINTENANCE AND SECURITY

All operators in our production workshop must hold legal operating certificates.

The cranes we produce are equipped with a safety monitoring system, which is professionally developed by the company in accordance with FEM/DIN/ISO/GB related standards, and is used for crane operation data recording, safety protection, and electronic instruments for status display.

The safety monitoring system has real-time protection functions for more than 30 working conditions such as operating failures, safety hazards and illegal operations, preventing the crane from operating in potentially dangerous situations and ensuring the safety of personnel and equipment.

Schneider TE is a vector frequency conversion control system specially developed for European crane components.

There is shock-absorbing plastic raw material derived wedges at both ends of the crane landing gear.

Overload protection, residual current relay, PTC thermistor, crash sensor, emergency stop button, sound/light warning and warning siren are standard protection units for all our overhead cranes.

At the time of delivery, we will provide customers with crane safety operation manuals and maintenance manuals. If the customer needs it, we will also send safety engineers to the site to know the customer's safe installation.
