The hydraulic portal lift is a complex consisting of 4 lifting towers, rail tracks, lateral movement units and a mobile oil station. The portal allows moving large-sized structures and loads in confined spaces where it is impossible to use a conventional crane.
The lifting towers (see image No. 1) are a welded structure designed for horizontal movement along rail tracks and lifting a beam with a load. The towers are driven by rotating the wheel axle of the trolley using a gear motor equipped with an encoder (the encoder is programmed for synchronous movement of the towers). This ensures protection against the occurrence of unwanted tilt angles, which can become a serious cause for the portal to tip over.
The rail tracks (see image No. 2) are designed and manufactured for the loads when moving the maximum loaded portal towers. A special guide rod, located in the center of the I-section, serves to ensure a strictly rectilinear direction of movement and performs a function similar to the flanges of crane wheels. Each section of the track is equipped with rigging welded loops, which serve for convenient transportation and movement of the product. The tracks are connected to each other by means of a bolted connection.
The lateral movement block consists of two roller earrings, which, using a screw-nut transmission, carry out lateral movement along the beam.
The hydraulic cylinders built into the lifting tower are driven by a hydraulic station, which, receiving signals from cable displacement sensors, transmits control to the valves, changing the feed so that the lifting is carried out strictly synchronously, in order to avoid distortions. The station is made on wheels, which allows it to be moved along relatively flat surfaces manually without the intervention of outside equipment.
Advantages of portal lifts
- The lift is developed according to your technical requirements and features of cargo movement;
- The portal can be disassembled and transported in a truck to the place where rigging works are carried out;
- The portal is equipped with an emergency control panel on the lift stand. The control panel is designed to lower the load in case of hydraulic failure or lack of electricity;
- All portals are controlled from a personal computer;
- The lifting and lowering speed of the heavy load is synchronized, this is achieved by special telescopic hydraulic cylinders.
