Chuck type jacks according to the structural characteristics can be divided into rack jacks, screw jacks and hydraulic jacks. In addition to these 3 basic types, hydraulic jacks according to the same principle can be converted into sliding jacks, hydraulic lifting platform, tension machine, etc., for various construction occasions.
Chuck type hydraulic jacks is mainly used for all kinds of large storage tanks, power plant desulfurization tower, gas tank, asphalt tank flip lifting installation.
1, The chuck type jacks adopts low loose steel strand, as long as there is a reasonable bearing lifting point, the lifting height is not restricted;
(2) Through the chuck type jacks extension combination, lifting weight, span, area is not limited;
(3) The chuck type jacks is small in size, light in weight, large in carrying capacity, convenient and flexible in installation, especially suitable for small space or lifting of large indoor tonnage components;
(4) The chuck type jacks has the reverse movement self-locking, so that the lifting process, and the component can be locked at any position in the lifting process for a long time;
(5) The chuck jacks has a high degree of automation, convenient and flexible operation, with automatic operation, semi-automatic operation, single point adjustment, manual operation and other operation modes. Display LCD display, touch screen display, button operation panel display, very intuitive. And the control system has a self-correcting protection program, so that the wrong operation will not cause accidents.
(6) Construction with chuck type jacks, short construction period, low cost, good economic benefits.

When the chuck type jacks is used, the upper and lower card blocks are in working state after the lifting rod is inserted into the jack. When the oil pump is fed, the pressure oil enters the cylinder block from the lower nozzle. As the upper clamping head automatically pins the lifting rod, the lower clamping head is released at this time. Under the action of oil pressure, the piston rises and lifts the lifting rod upward with the load. When the piston is full of one stroke, the oil pump stops supplying oil and the load stops rising to complete the lifting process. When the oil is returned, the pressure oil enters from the upper oil nozzle. At this time, the locking lifting rod of the lower clamping head is stationary. Under the action of oil pressure, the piston returns and the hydraulic oil is discharged from the lower oil nozzle. When a stage of lifting work is completed, stop the oil supply, loosen the upper and lower clamping head, and then put down or pull out the lifting rod, and so on until the end of the whole work.
The core equipment of synchronous hydraulic lifting technology is controlled by computer, which can fully complete synchronous lifting, load balancing, attitude correction, stress control, operation locking, process presentation and fault alarm and other functions. It is a modern advanced equipment integrating machine, electricity, fluid, sensor, computer and control theory.
