Product Description Hydraulic gantry craneOverviewHydraulic gantry crane is a lifting equipment designed for moving large metallurgical equipment, 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.StructureThe equipment 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 10-300 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.1. Lifting unit (legs)The 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. 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. 2.Movable spreaderThe hydraulic motor drives the spreader (that is, the full stroke spreader), and the hydraulic motor drives the spreader to walk, and the moving spreader drives the heavy object to move on the beam. The weight can be moved arbitrarily within the span of the jacking leg, and the moving distance can be completed at one time, which is not restricted by other factors. The single mobile spreader has a same rated load capacity and can be combined to achieve precise positioning of heavy objects. 3.main beam and trackThe main beam and track are important parts 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. 4.Electrical control systemThe 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. Advantages of hydraulic gantry crane1. Large tonnage lifting: The hydraulic system can provide stable and huge torque, suitable for heavy loads (up to thousands of tons). 2. Precise control: Hydraulic transmission can achieve stepless speed regulation, soft action, and accurate positioning. 3. Strong adaptability: It can work in harsh environments such as humidity and dust, and the legs can be adjusted to adapt to uneven ground. 4. Flexible structure: No need for counterweight, stability is achieved through hydraulic balance, suitable for mobile or fixed installation.Main technical parametersMain technical parameters(All parameters can be customized according to customer requirements)Lifting capacity30-1200tWork pressure (MPa)≤25Minimum height when retracted (m)Customized according to customer requirementsMaximum height during lifting (m)Customized according to customer requirementsLifting full stroke (m)No less than 6mLifting speed (m/min)0-0.5(Adjustable)lowing speed (m/min)0-0.5(Adjustable)Track positioning center distance (mm)Customized according to customer requirementsTraveling drive modeHydraulic motor with reducer driveTrolley traveling speed (m/min)0-1(Adjustable)TrolleyHydraulic motor driveLateral movement stroke of lifting equipment Total travel Lifting equipment moving speed (m/min)0-1Maximum slope (°)<0.5° (0.9%)Maximum lateral inclination (°)<0.5° (0.9%) Technical Services1.If required by the customer, we can provide equipment installation guidance and provide free training to the technical personnel dispatched by the customer.2.
