Model MFSRA32

Vehicle restraints safety systems are a key component of efficient and safe modern loading docks. Vehicle restraints lock trailers into position at the loading dock. The vehicle restraint systems incorporate an integrated system of signal lights, inside on the vehicle restraint control panel and outside on the facility wall to communicate loading and restraint status to the dock attendant as well as the truck driver. To further increase safety, the vehicle restraint systems can be interlocked to other loading dock equipment such as dock levelers, inflatable dock seals and shelters, overhead doors through use of a common control panel.

The Pentalift Model LPR35 Vehicle restraint safety system offers rugged design, simple and reliable hydraulic operation, an extremely low height, a stepped hook arrangement to restrict trailer/vehicle movement, minimal maintenance and maximum product value. The loading dock has been rated as one of the most hazardous areas within most facilities. Serious loading dock accidents can result from such things as premature truck departure, trailer creep and collapsing landing gear on spotted trailers. The Pentalift Model LPHR35 Vehicle Restraint Safety System is a proven solution to loading dock safety concerns. The reliable hydraulic operation promotes continued use by the dock attendant. The extremely low lowered height accommodates trailers with increasingly lower rear impact guards (R.I.G.) as well as addressing issues related to dock access problems for trucks due to inclined dock approaches.


Proven hydraulic operation ensures that the vehicle restraint will function reliably in the toughest environments. This is very important based on the harsh environment that most restraints are subjected to. Hydraulic systems are proven to be extremely reliable and durable. Due to this, hydraulic systems are the activation method of choice in industries such as aircraft and heavy construction equipment. The use of hydraulics on a vehicle restraint eliminates problems associated with relying on external electric motors, linear activators and/or gas spring operation that are incorporated by other manufacturers.

  • 35,000lb restraining capacity.
  • Stepped hook arrangement provides dual lock positions to restrict trailer movement.
  • Dual side-by-side hook arrangement effectively increases the rear impact guard holding strength and the restraining capacity of the restraint.
  • Signal bar requires approximately 30lbs of pressure to activate, thereby eliminating false engagement signal.
  • 8-3/4″ lowered height facilitates “No impact” operation. Accommodates new lower vehicle Rear Impact Guards and meets 1998 NHTSA rear impact bar regulations for trailers.
  • Hydraulic cylinder activation offers proven reliability.
  • Heavy-duty mounting plate ensures simple yet secure installation.
  • Watertight and corrosive duty limit switches are suited for harsh applications.
  • Flood resistant, standard design and construction ensures reliable operation even if the unit has been submerged. Other manufactures offer this feature as an option or not at all.
  • PTFE bushings in combination with hard chrome plated pins for reduced maintenance, on all pivot points.
  • Positive lock-down mechanism holds unit in lowered position and allows easy release for engagement.

Rugged structural guard protects the restraint components from impacts such as snow removal equipment and yard trucks. “Open” guard design allows dirt and debris to naturally move away from restraint components as opposed to competitive designs with boxed in housings that retain and hold dirt and debris that fall into the restraint. With other manufacturers restraints, the boxed in housing causes cleaning of the restraint to be more involved and more frequent.


To facilitate enhanced communication with dock attendant and truck driver regarding the status of the loading / unloading operation and further increase dock safety.

  • Manually activated NEMA 12 control panel with two-position selector switch. High visibility lights are clear and bright.
  • Exterior high visibility lights and dual image safety yellow instruction signs provided as standard. Narrow width of light and signs facilitates easy installation between dock seal side pads. LED light bulbs are utilized for increased life and energy efficient power consumption.
  • A further enhancement to the deluxe light system shown above. The Pentalift model MFRSA32 vehicle restraint is equipped with a signal bar to automatically sense the vehicle rear impact guard when it is engaged and restrained. The signal lights are automatically switched when the signal bar contacts the trailers rear impact guard. Incorporates NEMA6 watertight and corrosive duty limit switch to ensure reliability
