May 18, 2016, 4:48 pm - 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.Air Powered Dock Levelers, though structurally the same, use a push button control station to operate a 115/1/60 blower, which inflates an air bladder to raise the platform. A mechanical assembly operates the hinged lip. Once the lip is actuated and fully extended, the dock attendant releases the control button and the dock leveler automatically lowers into position on the truck bed. Mechanical Dock Levelers are more cost effective at the time of purchase.Air Powered Dock Levelers cost more to purchase but because they have fewer mechanical components, require less maintenance and are more ergonomically accepted.

Pressure controls require the operator to constantly depress the control button to either raise or lower the lift table. Once the pressure on the control button is released, the vertical movement stops. This helps to ensure that the operator is in complete control of the lift table at all times.Pentalift can offer the option of moving to press and release controls only if there will be no riders on the lift table at any time.

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.

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 […]
