Product Description We are one of the largest and most professional crane manufacturers in China, with total sales of more than 1.6 billion US dollars last year, including sales of 11,000 sets of double-beam and gantry cranes, more than 73,000 sets of single-beam cranes, and more than 100,000 sets of electric hoist and accessories.We have an advanced, green, whole-industry chain, intelligent manufacturing industrial park, with an investment of 370 million US dollars and more than 4,700 employees, which has been established for more than 20 years.I really hope to have the opportunity to cooperate with you.We welcome you to visit our company.This is partially completed single beam bridge crane and double beam bridge crane are waiting for shipment.The gantry crane is shaped like a "door", the metal structure is like a portal frame, and the two legs are installed under the main beam, which can walk directly on the ground track, and the two ends of the main beam can have an overhanging cantilever beam. It is mainly used in outdoor freight yards, docks and other places, suitable for large span, high site.Mainly used in outdoor venues, such as freight yards, docks and other places. Due to its unique structural design, gantry cranes are suitable for large span and high height sites, often used for loading and unloading large goods, such as containers, steel and so on. Its carrying capacity is large, and it can meet the lifting needs of large objects.The safety devices of bridge cranes mainly include the following types: oneLift height (lowering depth) limit switch: When the lifting gear rises or lowers to the extreme position, this device can automatically cut off the power source to prevent the hook from hitting the top or lowering too deeply, thereby avoiding safety accidents such as the hook falling. Operating travel limiters: Travel limiters must be installed on each operating direction of the crane and trolley. When the designed limit position is reached, the power source in the forward direction is automatically cut off to ensure that the equipment operates within the range of the travel limit position. Load limiter: Also known as an overload protector, when the load reaches 1.05 times the rated load capacity, this device will cut off the upward movement but allow the downward movement to prevent the crane from lifting a load exceeding the rated load capacity. Anti-collision device: When two or more cranes are operating on the same track or there is a possibility of collision, the anti-collision device will trigger the electrical switch to act, cutting off the power supply and stopping the crane to prevent collision accidents. Interlock protection device: For the doors of cranes and the doors from the driver's cab to the bridge frame, unless the operation manual specifically states that the door can be opened and safety can be guaranteed, interlock protection devices should be installed. When the door is open, the power supply should not be connected. If the crane is in operation, when the door is opened, the power supply should be cut off and all mechanisms should stop running. Other safety protection and safeguarding devices: including buffers, end stops, wind-resistant and anti-skid devices, alarm devices, emergency stop switches, track sweepers, protective covers, guardrails, etc. These devices provide additional safety guarantees in various situations. These safety devices work together to ensure the safe operation of the bridge crane and prevent various potential safety hazards and accidents.
