Product Description Worm gear screw lift system rack Jack pinion landing rod trolley hand crank geared bottle reduction swl base shoring heavy duty four lifting car jacks jack Product Description We hereby introduce our company as a leading manufacturer of mechanical jack, rack steel jack in China.We have CE and GS certificate for our quality system.Rack and Pinion Jacks illustration as follows:Product Usagerack and pinion mechanical jack is a safe, practical and convenient lifting, its greatest advantage is to overcome the hydraulic jack hydraulic leak Er Shi as top heavy drop from the shortcomings, it maintain a long stay in the support position, so particularly suitable for upgrading of the heavy long position after the occasion demands. Some frequently used in the following situations:1. Mechanical assembly and repair of vehicles from the top of the machine when used, vehicles and equipment used to from the top of prefabricated construction, etc..2. Railway sector maintenance when used in railway tracks from the top.3. Mines, tunnels, bridges, concrete poured in the pit prop support.4. Loading and unloading will be prostrate, lifting a lower position of the items before the pre-top.QJC-B TYPE GEAR&RACK MECHANICAL JACK SPECIFICATIONS Model QJC-1.5BQJC-3BQJC-5BQJC-10BQJC-16BQJC-20BRated capacityt1.535101620Test loadkN18.436.861.3122.5196245Lifting heightmm350350300300300400Min.start jacking heightOver-bracketmm725725725800800950Under-bracketmm7075758595110Lifting height for the handle turn a ringmm158.54.35.03.52.5The handle pull to lift full loadN280310350680680700The number of operatorPCS111222The handle turning radius Rmm250250250300300300DimensionsmmA125185192242285376B293304330485492505B1193204232254282295H722724724796798948h6872748293108L130130130250250250W130130150150160200P140140170170190230Net weightkg14.52130496893Advantages of Screw jacksHigh lifting capacity: Jacks, especially hydraulic jacks, are able to lift loads heavier than human effort. This makes them indispensable tools for heavy machinery, vehicles, and structural members.Compact size: Despite their high lifting capacity, many types of jacks, such as bottle jacks or floor jacks, are relatively small and portable. This makes them convenient for use in confined spaces or transported with vehicles.Efficient lifting, labor-saving: Hydraulic jacks use Pascal's law to amplify force. Only a small amount of human effort applied to a lever or pump can generate huge pressure in the hydraulic oil, which is converted into huge lifting force. This reduces the physical strain on the operator.Precise control: Hydraulic jacks provide smooth and controlled lifting, allowing operators to adjust the height precisely. This is essential for safe and accurate positioning of loads.Stability and durability: Designed with strong materials and structures, jacks have excellent stability under heavy loads and are durable and have a longer service life with proper maintenance.Versatility: Jacks come in a variety of types and capacities to accommodate a variety of environments and lifting needs across different industries.Low loading height (some types): Some jacks, such as toe jacks, can lift loads very close to the ground, which is beneficial for low-headroom equipment.Applications of jacks1. Automotive IndustryVehicle Maintenance and Repair: The most common application. Jacks are used to lift cars, trucks, and SUVs for tire changes, brake checks, suspension repairs, and general chassis maintenance.Emergency Roadside Assistance: An essential tool for changing flat tires.Transmission Jacks: Specialized jacks used to safely raise and lower heavy vehicle transmissions during repairs.Forklift Jacks: Used to raise the forklift itself for tire changes or maintenance.2. Construction IndustryStructural Support and Leveling: Used to raise and level heavy structural components such as steel beams, concrete slabs, and precast elements during building construction or renovation.Heavy Equipment Handling: Assists in positioning or moving large construction machinery.Bridge Maintenance: Used to lift bridge sections for repair or inspection.House Lifting and Relocation: Large mechanical screw jacks or hydraulic jacking systems are used to lift entire houses or buildings for foundation repairs or relocation.3. Industrial and ManufacturingMachinery Installation and Maintenance: Lifting and positioning heavy industrial machinery, presses, dies, and other equipment for installation, repair, or calibration.Material Handling: Used to raise and level heavy pallets or equipment in warehouses.Assembly Lines: Used to precisely position components during assembly.Heavy Presses: Used as the core lifting mechanism of various hydraulic presses.4. MiningEquipment Maintenance: Lifting heavy components of mining machinery (e.g., excavators, dump trucks) for repair or replacement.Heavy Lifting: Assists in the safe and controlled movement or repositioning of large rocks or equipment.Support and Stabilization: In some cases, used to temporarily support or stabilize structures or ground in certain mining operations.5. Marine and ShipbuildingShipbuilding and Repair: Used to lift and adjust large ship components during construction and during dry dock maintenance.Loading and Unloading: Assists in positioning heavy components onto finished ships.6. Rail and TransportationTrack Maintenance: Raises and lowers track sections for installation or repairs on the track system.Train Car Maintenance: Used to lift train cars or locomotives for chassis work.7. Other ApplicationsAgriculture: High-lift jacks (farm jacks) are popular with farmers for lifting tractors, trucks, and other farm implements in rough terrain or in emergency situations.Emergency Rescue: Used by emergency services to free vehicles or lift debris during rescue operations.
