Dock usually is a place on the harbor where ships go for loading, unloading and repairing. Dock lifts are the most important machines on the harbor as all the loading and unloading of the cargos from ships and movements of material is done with the help of these lifts. Manpower is used to control the lifts, but manually it is impossible for man to load and unload the cargo themselves as no man has strength to lift such heavy containers and machineries without the help of dock lifts. Dock lifts vary from type to type depending on the nature and quality of their work and for what purpose they were built for. Like for example the lift which unloads containers from ships and keeps on the docks, the same lift will not be used to move the containers on the port and place them. There are lifts with different names and functions which are very important to be used on the docks, they are as follows: Dock Levers Dock levelers are used to allow easy transfer of goods from the docks to the trailers. They create a bridge between the dock and the trailer thus ensuring easy and safe movement of material. Depending upon their drive mechanism, dock levelers are of three types - Mechanical, Hydraulic, and Pneumatic. Mechanical levelers are the least expensive, in this type of leveler, the spring and chain action causes the deck to move up and down. The docks that handle large volume of material generally use hydraulic levelers. This type of leveler is automatic and gets activated with a push button. Pneumatic levelers use air bags to move the deck up, these are gaining popularity because they are simple to use and easy in operation and low maintenance. While choosing one leveler, one should keep in mind the volume of material handles, the load that the leveler should be able to carry, and the height adjustment. Vehicle Restraint This equipment is used to enhance the safety at the dock. Since the accidental movement of truck during loading, unloading or parking at it can cause mishaps, vehicle restraints are used to keep them in place. One can use mechanical, Electro-mechanical or Electro-hydraulic vehicle restraint in their facility. Dock Seals This loading equipment is used to fill the gaps between the trailer and the dock door. This helps to prevent the leakage of air, which is the major cause of loss of energy at them. It also improves the safety of material and helps prevent contamination of the stored material, which could occur due to air infiltration. There are different types of dock seals. Among them the inflatable seals are the most widely used. They seal both the sides and top of the trailer. Pad seal is another popular dock sea, because of its low cost. Besides these 3 major equipments there are much other equipments which are smaller in size but very helpful in operation such as small lifters, trawlers, loaders and etc. Visit for boat lift parts and Boat lift repair at marineliftanddocksupply.com.
