Transporting equipment’s, vehicles and other such heavy devices could be risky if you are not using dock levelers. Not just can it be risky to the people involved, but can cause damage to the objects being transported.
The dock levelers are there to make transportation a smooth affair. The dock levelers (also called dock plates or dock boards) are a tool which people can exercise to fill the gaps between trailers and dock while the loading or unloading takes place.
Trailers are of the height that sometimes is not the same as of the dock (either higher than or lower than the dock). The main function of dock levelers is to move things up or down, based on where the trailer bed is situated. Hence, machines like forklifts can travel to the dock safely and smoothly.
There are multiple kinds of dock levelers such as Hydraulic, Mechanical, Air-powered, and Specialty. Hydraulic consists of Standard Hydraulic (RHH), the Vertical Hydraulic (RHV) and the Jumbo (RHJ) that offers full-width trailers’ access.
Air-Powered dock leveler contains Air-Tower (RHA). It is like hydraulic leveler and avoids any possible stump-out problem. The Mechanical dock leveler consists of Standard Mechanical dock levelers (RHM) and Edge-of-Dock levelers (RHE). The Truck and Railcar Activated are Specialty dock levelers for trucks and railcars.
The types of machines or vehicles you will be transporting must be considered while deciding about the dock leveler you will use. The dock levelers you select should match your needs for all the given situations. Also, the trailer or vibrating table dimensions, how often loading will be done and the load capacities should be considered while selecting the dock levelers.

A telescopic hydraulic cylinder is used to achieve the inclination. These are primarily of two types: the single acting telescopic type and the double acting telescopic cylinder type. Both of them are used in several areas.
The use of hydraulic power makes the difficult work smoother and easier. Attaining a specific degree of inclination can be difficult without proper instrumentation. A multilevel telescope cylinder makes this possible.
The most common example of the use of a telescopic cylinder is in a dump truck. In order to throw away the trash, the container part of the truck needs to be raised at an angle of about 60 degrees.
Focus is on a high efficiency, durability and performance. The telescopic hydraulic cylinders are customized and standardized as per the specifications of the customers. Essem offers a special design of hydraulic cylinders that can lead to an exceptional and long productivity from a compact retracted length.
A telescopic hydraulic cylinder is commonly applied in cases where the dump body on a dump truck is used in a construction site. In order to empty the load of gravel completely, the dump body should be raised to an angle of about 60 degrees. To achieve this long travel with a conventional hydraulic cylinder is very difficult considering that the collapsed length of a single stage rod cylinder is approximately 110% of its output stroke. It becomes very challenging for the design engineer to fit the single stage cylinder into the chassis of the dump truck with the dump body in the horizontal rest position. However, the above mentioned task is easily accomplished using a telescopic style multi-stage cylinder.
Manufacturing of some pneumatic telescoping units is done with retracted lengths of under 15% of overall extended unit length. This feature is very attractive for machine design engineers when a conventional single stage rod style actuator will not fit in an application to produce the required output stroke.
Heavy duty telescopic cylinders are typically powered by hydraulics, while some units which are lighter duty could also be powered by compressed air.
Constructing a hydraulic cylinder is tricky considering its work of collapsing and expanding to 20 to 40 % of its height. A lot of expertise is required to bring out the best product.
