ANSI MH30.1-2022 Design, Testing, and Utilization of Dock Leveling Devices, (a revision of ANSI MH30.1-2015)
The purpose of this standard is to serve as the guide for designers, manufacturers, sellers, installers, owners, users, and governing bodies of dock leveling devices and to achieve the following objectives:
-
to provide guidelines for the design and testing of dock leveling devices;
-
to promote the understanding of the respective responsibilities of manufacturers, sellers, installers, designers, owners, users, and governing bodies associated with dock leveling devices; and
-
to provide a uniform means of comparison for dock leveling devices.
A dock leveling device is a manufactured structure designed to span and compensate for space and height differentials between a loading dock and a transport vehicle to facilitate freight transfers in an effective and efficient manner. The three types of dock leveling devices within the scope of this standard are described in the following paragraphs.
-
dock-face mounted type: A dock-face mounted dock leveling device is permanently affixed to the face of a dock. Also known as edge of dock (EOD) levelers.
-
fixed type: A fixed dock leveling device is affixed to the dock structure and usually incorporates a mechanism to aid in positioning the leveling device with respect to a transport vehicle. Fixed types include both horizontal and vertical storing levelers.
-
rail dock leveling device: A rail dock leveling device is a manufactured structure designed to span and compensate for space and height differences between a rail car loading dock and a rail car to facilitate effective and efficient freight transfer or passage.
-
fixed type: a structure designed for stationary mounting to the dock, located at either the dock face or recessed into a pit. Placement of the bridging structure into a working or stored position will usually be aided by a mechanism incorporated into the design.
-
sliding type: a structure designed to be permanently mounted to a dock face with a mounting assembly that allows for lateral movement of the bridging structure parallel to the dock face. Placement of the bridging structure, either laterally along the dock or into the stored or working position, may be manual or with a mechanism designed to aid in such positioning.
Performance and testing requirements for portable dock leveling devices are provided in ANSI MH30.2 2022.

ANSI MH30.2-2022 Design, Testing, and Utilization of Portable Dock Leveling Devices, (a revision of ANSI MH30.2-2015)
This standard defines performance and testing requirements for the design, use, and maintenance of portable dock boards and dock plates, collectively known as portable dock leveling devices. The purpose of this standard is to provide a uniform means of comparison, improve user confidence and knowledge, and to define product requirements for portable dock leveling devices.
A dock leveling device is a manufactured structure designed to span and compensate for height differentials between a stationary loading dock and a movable transport vehicle to facilitate effective and efficient freight transfers. Dock leveling devices may be either built-in or portable. Dock leveling devices are designed to be capable of withstanding typical loads imposed by material handling equipment.
A portable dock leveling device is not permanently affixed to either the transport vehicle or the dock structure. It is capable of
being moved from one location to another by manual effort or by independently powered equipment. Portable dock leveling devices are commonly
referred to as dock boards or dock plates. Dock boards are typically designed to be capable
of withstanding heavy-duty loads imposed by material handling equipment, while dock plates are typically used in lighter-duty hand
loading or hand truck loading applications.
Performance and testing requirements for built-in dock leveling devices are provided in ANSI MH30.1-2022.

ANSI MH30.3-2022 Design, Testing, and Utilization of Vehicle Restraining Devices, (a revision of ANSI MH30.3-2015)
This standard defines performance and testing requirements with regard to design, use, and maintenance of vehicle restraining devices. The purpose of this standard is to provide a uniform means of comparison, to improve user confidence and knowledge, and to define requirements for vehicle restraining devices.
A vehicle restraining device is a manufactured structure designed to interface between a loading dock and a transport vehicle. It is intended to facilitate effective and efficient freight transfers by limiting vehicle motion and preventing unanticipated departure or vehicle creep. Vehicle restraining devices commonly incorporate a communication light system between the dock worker on the inside of the building and the transport vehicle driver on the outside. The two types of vehicle restraining devices within the scope of this standard are described below.
-
rear impact guard (RIG) type: this is the most common type of vehicle restraint. It is a vehicle restraint that engages the RIG of a transport vehicle, inhibiting uncontrolled separation of the vehicle from the dock face;
· NOTE – these are also known as “ICC bar restraints.”
-
wheel dependent type: A vehicle restraint that engages one or more wheels of a transport vehicle, inhibiting uncontrolled separation of the vehicle from the dock face.
Vehicle restraining devices are further classified according to manual vs. powered operations:
-
manually operated: a vehicle restraining device that is both engaged and released manually;
-
power operated: a vehicle restraining device that is both engaged and released through a powered means, either with a push-button or automatic operation.
