MATE-LH electric double-beam bridge crane is a new type of bridge crane. The whole machine adopts European standard modular design, with compact structure, light weight and low noise. The whole machine adopts frequency conversion control. The lifting can choose a dual-speed motor, which is energy-saving, environmentally friendly and maintenance-free. It is a new type of bridge crane with a higher working level (optional explosion-proof type).
Electric double-beam bridge crane composition: It consists of bridge frame, lifting mechanism, trolley running mechanism, trolley running mechanism and electrical system.
■ European technology, modular design, light weight, small wheel pressure, safe and reliable, green concept leads innovation, saves space and energy.
■ Full frequency conversion control, the walking mechanism and lifting mechanism adopt three-in-one motor reducer, which runs smoothly, safely and reliably.
■ High working efficiency, the working level can reach A5-A6.
■ It can be customized according to specific application requirements.
■ Lighter weight, lower wheel pressure and lower energy consumption.
■ Standardization, generalization and serialization of parts.
Main beam mechanism: generally adopts square box beam design, and the main welds are non-destructively tested to ensure welding quality. All steel plates are shot blasted to Sa2.5 standardization. The steel plates will be carefully inspected and cleaned before welding, and are usually welded by automatic welding machines. The steel plate material is Q235B. Q355B and Q355E low temperature resistant plates are suitable for use in minus 40° environments.
End beam mechanism: It is welded and formed by rectangular steel pipes or steel plates. After the end beam is welded, it is processed in one go on a CNC boring and milling machine to ensure dimensional accuracy and matching tolerance. The main beam and the end beam are connected by high-strength bolts and positioned by locating pins to ensure the accuracy of the whole machine and smooth operation.
Wheel mechanism: Double-ring wheels are used. The wheels are made of 40Cr or 42CrMo alloy steel, QT600, 65Mu and other materials, and are tempered as a whole, with high hardness, wear resistance and long service life.
The wheel bearing is a self-aligning bearing. When the bearing is subjected to an eccentric load, the roller will automatically adjust its position so that the bearing always keeps in contact with the axis, thereby improving the stability of the equipment operation.
Lifting mechanism
Motor: Usually a dual-speed motor or a variable-frequency motor is used. The variable-frequency motor can achieve stepless speed regulation to meet different lifting speed requirements. The dual-speed motor uses a dual-winding motor to achieve dual-speed control.
Reducer: A precision planetary reducer or F series parallel shaft reducer is used. The reducer size uses a hardened tooth surface, which is maintenance-free, does not require oiling, and has low noise.
Drum: A cylindrical cylinder with a spiral groove on the surface, which is used to wind the wire rope and realize the retraction and release of the wire rope through forward and reverse rotation.
Wire rope: 8*26-2160 high-strength galvanized wire rope is used.
Pulley block: The material is divided into high-strength nylon or Q235 material.
Brake: An electromagnetic brake is used. When the power is off, the brake is automatically clamped to prevent heavy objects from falling; when the power is on, the brake is released to allow lifting.
Operating mechanism: It adopts a three-in-one drive system of motor, reducer and brake, which has compact structure, high transmission efficiency, stable operation, reliable braking and simple maintenance. It realizes three-in-one drive to improve the safety and reliability of the equipment. The motor adopts a three-phase AC variable frequency motor. The reducer adopts a hard tooth surface reducer. The brake adopts an electromagnetic brake, and adopts asbestos-free brake pads and brake discs.
Electrical system: Cranes often use variable frequency speed regulation technology. The frequency converter can change the frequency of the output power supply according to the instructions of the PLC (programmable logic controller), thereby adjusting the speed of the motor. The layout design of the control box is reasonable, easy to maintain, and the protection level is IP54.
Crane power supply system: The following methods are adopted: 1. Seamless safety busbar 2. Tubular busbar 3. Single-machine H series safety busbar 4. Steel conductor busbar 5. Cable drum 6. Lithium battery power supply. Different power supply systems are adopted according to different use environments.
Crane operating system: 1. The cab has a wide field of view, linkage control, easy operation and better field of view. 2. The wireless remote control adopts a two-speed button or a four-speed remote control, which is stable and accurate, can realize remote control, is easy to operate, has a protection level of IP65, and a service life of 500,000 times. 3. The wired handle can resist interference and has a long service life.
Protective device:
1. Equipped with a protective cover and guardrail to prevent the hook from hitting the top device.
2. The lifting mechanism is equipped with a height limiter. When the hook rises to the preset limit height, the limiter is triggered and the power supply of the lifting motor is immediately cut off, so that the hook stops rising and prevents the hook from hitting the top.
3. Overload protection is equipped with a high-precision overload limiter to monitor the lifting weight of the crane in real time. Once the lifting weight exceeds the set ratio of the rated lifting weight (usually 105% - 110%), the overload limiter will quickly send out an audible and visual alarm signal, and automatically cut off the lifting power circuit, prohibiting the crane from continuing the lifting operation.
4. Travel limit protection "Both the trolley and the trolley operating mechanism are equipped with travel limit switches. When the trolley or trolley runs to the limit position at both ends of the track, the limit switch is triggered, and the power supply of the running motor is immediately cut off to stop the crane from running, avoiding the crane from running out of the track and causing derailment, falling and other dangers.
Electrical protection: short circuit protection, overload protection, grounding protection
Application scenarios of electric double-beam bridge cranes: construction industry, industrial and mining workshops, machinery manufacturing workshops, metallurgical workshops, petroleum and petrochemical, railways, civil aviation, power stations, papermaking, building materials, electronics and other industries, factories and warehouses, etc.
