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. If the velocity fuse senses any sort of flow that is too fast then the velocity fuse will close locking the oil in the cylinders stopping the lift from lowering. This ensures safety to the operator to minimize any risk of injury.

Pentalift lift tables can have additional options included that will permit use as a work platform , or for riders to travel with the load.
When there will be personnel riding on the table, the industry standard, ANSI MH29.1 Safety Requirements for Industrial Scissor Lifts, requires that the lift table be equipped with guard rails on all sides These are not used for loading and unloading, unless guarded by location or other means. On sides and ends that are used for loading and unloading, the... Read More
Only if you are using a lift truck on your dock lift would you require an Automatic Hydraulic Roll-Off-Stop.
When the dock lift is in the lowered, closed position, the roll-off-stop is flat. The lift truck drives across the roll-off-stop onto the platform. When the "up" button is activated, the roll-off-stop is powered into the vertical position before the dock lift begins to rise.
When the dock lift is in the raised position, the lift truck drives onto the delivery truck. When the lif... Read More
By default, the standard operator controls for lift table applications are constant pressure buttons on handheld pushbutton pendants.
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 relea... Read More
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 contro... Read More
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... Read More
Employee safety is the number one priority for manufacturing businesses. Working with a wide range of machinery and in variable conditions can present a number of safety risks, but making sure your employees use personal protective equipment (PPE) protects them and reduces the costs associated with workplace injuries.
But it’s not always easy to ensure that employees are using PPE properly. It’s up to you to provide the education and resources they need to understand how and why they shou... Read More
