The purpose of a velocity fuse is to ensure safety to any operator using a hydraulic lift table, hydraulic dock lift, or a hydraulic dock leveler. The way it works is by regulating flow leaving the cylinder.

This ensures safety to the operator to minimize any risk of injury. Contact a Pentalift sales Representative for more informati... Read More
<b/r>Dock levelers are manufactured with 3 operating styles. They are mechanical (spring), pneumatic (air), and hydraulic (oil). <b/r> Mechanical is initially the least expensive, however they require an element of physical effort to both raise and lower the platform. From an ergonomic and safety perspective, hydraulic dock levelers provide the best performance. If the mechanical dock leveler is structurally sound, it makes perfect sense to convert to fully hydraulic operation. Th... Read More
Hydraulic levellers are automatic and work at the push of a button. On the other hand, mechanical pit levellers are activated with a pull chain. However, there are more things that set the two types of levellers apart. If you’re not sure which one is best for your warehouse, the differences are listed below. Activation and usage The mechanical type of dock leveller is spring-powered and needs manpower to be activated. The machine needs to be positioned first onto a trailer or platform by... Read More
