Hydraulic Dock Levellers

In the past few years, this type of leveler was the only substitute to a manual leveler. It was known as the mechanical leveler. A hydraulic dock leveller utilizes a simple hydraulic circuit. It consists of a valve, cylinder, and a pump to lower and raise the leveler platform.

Throughout the world, there are tons of hydraulic levelers in use. This is the main reason why hydraulic dock levellers are a reliable device for the industry. However, after the invention of air-powered and mechanical units, hydraulic levelers today are now the 3rd popular device. When considering system repair and maintenance, the commonness of hydraulics is a huge plus. There are tons of trained professionals to maintain or repair hydraulic systems. In addition to that, these devices are ideal for heavy-cargo uses.

Air-Powered Dock Levelers

Air-powered levelers utilize an airbag to lower and raise the leveler platform, unlike the hydraulic one which utilizes a hydraulic cylinder. The airbags of an air-powered system are not the same as the airbags that are used in a car. That is what most individuals think of when they hear the word airbag. The airbags in an air-powered unit are made from a polypropylene fiber membrane that is thoroughly woven and coated with a hard PVC shell. These types of airbags take benefit of their size to carry heavy cargoes with little air pressure (around 4 PSI).
