Farm Jack - mobile (portable) device that allows you to lift loads on different height.This type of device is widely used in many areas due to various types of structures and the hallmark of other lifting devices is that they are placed under the weight, not over it.Farm Jack is very popular among motorists, thanks to its compactness and simplicity of the device.They can be cast iron or steel rail, and lift the load, they can at the very height of the rack.
In general, jack rack in all spheres is quite popular.The essence of the mechanism is that its design has a rack that has a special bearing cup.The mechanism is driven by the rotation of the lever that moves the goods in the rail with the support cup.
jack rack DR-5 is designed to lift the load by means of a manual drive.This type of device capable of lifting the load on a small height with a high degree of accuracy, while requiring a minimum amount of physical effort.Farm Jack DR-5 is in its functional equipment truck brake, whose main task - ensuring retention lifted load.It is important that this is observed is proportional to the load on the axis of the rail.
distinctive features of these mechanisms is that they represent a compact device that does not require any complicated manipulations in operation.When lifting the load is provided by the high level of ride.Due to the extended base of the jack has increased stability, and its load capacity is 5 tons.All these positive features make this device indispensable in some areas of the industry.
jack rack DR-10 has a ratchet mechanism that ensures safe operation and records the load during lifting.High maintainability and reliability make these devices ideal for use in complex technical environments.Capacity jack DR-10 is 10 tonnes, which expands the scope of its application as compared with the previous views presented.
pinion jack allows you to stop the rise of the load at any height, and the shipment will be securely locked.The scope of the hoisting determine their technical capabilities: the device type, capacity, availability, and other advanced features.
As noted above, the most popular such arrangements received from motorists, especially those who prefer flat roads roads.In such extreme conditions, this type of lifting device is the ideal mate.
jacks capable of lifting more than 10 tons, used mainly in construction and laying of railroad rails.They can also be used not only in horizontal but also in vertical plane, the main requirement is to have a reliable support.The maximum possible payload rack jack is 20 tons.
Farm Jack addition, there are screw, hydraulic and pneumatic types.
