Product DescriptionProduct Description400ton hydraulic gantry craneHydraulic gantry cranes are mainly used in space limited and heavy lifting situations, such as the installation of large transformers, the installation of large ship propellers, and the transportation of large equipment in workshops.Hydraulic gantry crane is a lifting equipment designed for moving large metallurgical, electrical equipment or other heavy components. The equipment can realize hydraulic jacking, drive walking, side movement of spreader, and three-dimensional attitude adjustment of goods. It is mainly composed of a set of basic jacking units including jacking and walking functions. The jacking unit is equipped with a hydraulic pump station as a power source. It adopts centralized electric control and relies on hydraulic drive to realize the jacking and walking of heavy objects.The system is mainly composed of four groups of jacking unit, hydraulic station, mobile spreader, beam, track beam and wireless remote control. The jacking unit has a carrying capacity of 100 tons per unit. The lifting unit is placed on the walking track, supplied with oil by the hydraulic pump station, and adopts a closed-loop control method of continuously variable speed motor to achieve synchronous lifting and synchronous walking between the legs..Features and Advantageshydraulic pump stationThe hydraulic pump station adopts a centralized design, which means that four lifting units are equipped with one hydraulic station, and variable speed control is used to achieve speed control of lifting and walking, flexibly adapting to operational needs.The synchronization between the legs is achieved through a centralized control system.lifting unitThe jacking unit includes jacking oil cylinder, driving motor, reducer, corresponding mechanical structure, etc. The legs are guided by a single stage telescopic structure to ensure the safe bearing and operation. Large tonnage hydraulic cylinder lifting telescopic action, can achieve a full stroke of lifting. The lifting leg, as a key component for carrying lifting, has a dual locking device, hydraulic locking and mechanical cam locking, which can ensure safety and reliability. There is a spherical roof at the top of the lifting unit to adapt to the small displacement of the correction, mechanical has a good guide device, compact structure, make the whole lifting leg more stable and reliable. The walking of the lifting leg is achieved by driving the planetary reducer with a hydraulic motor, and the operating speed is adjusted by variable speed regulation. All actions are driven by hydraulic transmission, using high standard hydraulic components to ensure system safety.Beam (main beam) and trackThe main beam and track is an important part of the hydraulic gantry crane, and it is also an essential part of the gantry crane work. The main beam mainly carries heavy loads and transfers the force to the lifting leg. Track is an important factor to realize safe and stable running of gantry crane. You can't do one without the other. Lower deflection of main beam < 1/750. Anti-rust treatment should be done in the closed structure space of the track and main beam. The main beam should be treated as a whole by shot blasting and quickly painted after shot blasting. The thickness of the paint film should be ≥120um. Gantry crane has C5 coating for corrosion protection and the panel has canopy / cover for rain and sun protection.Electrical control systemThe oil cylinder is driven step by stepThe lifting point is driven by a hydraulic motorThe electrical system is controlled by PLC, and the hydraulic station is variable speed regulation. Each leg is equipped with lift height sensors that provide real-time feedback on the current height and operation synchronization. When there is a difference, the control system can automatically adjust the oil supply flow of each branch through variable adjustment, so as to achieve accurate synchronization between each branch. The operator can also adjust and operate each independent leg separately according to the situation. Centralized control pump station can achieve remote control of the entire gantry crane system, which is safe, reliable, easy to operate, intuitive interface, and can monitor the movement of the load at any time.The mobile lifting gear can move the load along the direction of the crossbeam to achieve the precise positioning of the heavy object. The mobile lifting gear has a strong load-bearing capacity and a high safety factor. It is propelled by a hydraulic cylinder to achieve movement, thus facilitating the change of the load position. Both single-beam and double-beam models are available with the option of mobile lifting gear, and the installation position of the lifting gear on the crossbeam can be freely adjusted.The hydraulic motor drives the lifting gear (i.e., the full-travel lifting gear), and the lifting gear moves by the hydraulic motor. The moving lifting gear drives the heavy object to move on the crossbeam. The heavy object can move freely within the span of the lifting outriggers, and the moving distance can be completed in one go without being restricted by other factors. The rated load capacity of a single mobile lifting gear is 100 tons, and it can be combined to achieve precise positioning of heavy objects.Fixed lifting pointAccording to the pre-designed hoisting plan, place the fixed lifting gear on the crossbeam. During the hoisting process, the heavy object, the fixed lifting gear and the crossbeam move forward and upward together with the lifting outriggers. The heavy object cannot move along the direction of the crossbeam within the span of the lifting outriggers. It is mainly applicable to situations where the position of the lifted heavy object does not need to be adjusted.Specificationlifting capacity200ton400ton800ton1000tonpower modelexternal power source/engine/generatorlifting heigh6-35mspan6-20mDetails ImagesPacking & Delivery1. Electric parts are packed by high quality plywood crate, to reduce distortion in conveying. 2. Main beams, end beams and trolly/winch are packed by plastic woven cloth. It can reduce abrasion during the transportation. 3. If the size are suitable for container ship, usually by container. 4. Big size, usually by bulk ship or by container after truncation. 5. Transport ways are based on reducing cost & keep safety
