May 6, 2016, 8:41 am - That’s a very common question that is raised when decisions are made related to dock leveler selection. Mechanical dock levelers use a series of springs and levers to raise the platform and extend the lip assembly. The mechanical dock leveler is then “walked down” into position on the delivery truck bed. Hydraulic dock levelers, though structurally the same, use a push button control to operate the dock leveler. When the button is pushed, an electric motor starts and a hydraulic cylinder is used to raise the platform. A second hydraulic cylinder is used to extend the lip assembly. When the dock attendant releases the control button, the dock leveler automatically lowers into position on the truck bed. Mechanical dock levelers are more cost effective at time of purchase. Hydraulic dock levelers cost more to purchase, however require less maintenance and are more ergonomically accepted. Contact a Pentalift Sales Representative for more information.

April 29, 2016, 10:32 am - A Velocity Fuse is a safety device that is added to the hydraulic system. It “locks” the downward travel in a free-fall situation, which occurs due to a hydraulic system failure, other than on the cylinders of the lift table. The Velocity Fuse monitors the flow rate of the hydraulic fluid out of the cylinder and “locks” if it exceeds the allowable rate. For lighter loads, a flow rate high enough to “lock” may not develop. In these cases, the downward travel will be at a controlled speed.Contact your Pentalift Sales Representative for more information.
April 29, 2016, 9:50 am - The biggest risk commercial goods face is being damaged in transit. The jerky movement of the vehicle increases the chances of the goods arriving at their destination in damaged condition. Dunnage airbags are designed to lessen the impact of this movement and preserve the integrity of the merchandise. This is crucial for saving time and […]
April 22, 2016, 12:06 pm - If the overhead door is closed and locked, a mechanical dock leveler will not damage the door when the dock leveler is activated. An air powered dock leveler or hydraulic dock leveler will cause extensive damage to the closed and locked overhead door if operated. To address this concern for potential damage, both air powered and hydraulic dock levelers can be ordered with an optional overhead door interlock switch. A striker plate on the door activates a wall installed limit switch when the door is opened. Only when the limit switch is activated, will the dock leveler operate.
