7)  Loading dock safety equipment should never 

be used outside of its vertical working range, or 

outside the manufacturer’s rated capacity.  It shall 

also be compatible with the loading equipment 

and other conditions related to dock activity. 

Please consult the manufacturer if you have any 

questions as to the use, vertical working range or 

capacity of the equipment. Only properly trained 

and authorized personnel should operate the 

equipment. 

8)  It is recommended that the transport vehicle 

is positioned as close as practical to the dock 

leveling device and in contact with both bumpers. 

When an industrial vehicle is driven on or off a 

transport vehicle during loading and unloading 

operations, the transport vehicle parking brakes 

shall be applied and wheel chocks or a restraining 

device that provides equal or better protection of 

wheel chocks shall be engaged. Also, whenever 

possible, air-ride suspension systems should have 

the air exhausted prior to performing said loading 

and unloading operations.  

9)  When goods are transferred between the loading 

dock and a trailer resting on its support legs/ 

landing gear instead of a tractor fifth wheel 

or converter dolly, it is recommended that an 

adequate stabilizing device or devices shall be 

utilized at the front of the trailer.  

10) In order to be entitled to the benefits of the 

standard product warranty, the dock safety 

equipment must have been properly installed, 

maintained and operated in accordance with 

all manufacturer’s recommendations and/

or specified design parameters and not 

otherwise have been subject to abuse, misuse, 

misapplication, acts of nature, overloading, 

unauthorized repair or modification, application in 

a corrosive environment or lack of maintenance. 

Periodic lubrication, adjustment and inspection 

in accordance with all manufacturers’ 

recommendations are the sole responsibility of the 

owner/user. 

11) Manufacturer’s recommended maintenance and 

inspection of all dock leveling devices shall be 

performed in conformance with the following 

practices: A planned maintenance schedule 

program must be followed, only trained and 

authorized personnel shall be permitted to 

maintain, repair, adjust and inspect dock leveling 

devices, and only the use of original equipment 

manufacturer parts, manuals, maintenance 

instructions, labels, decals and placards or 

their equivalent. Written documentation of 

maintenance, replacement parts or damage 

should be kept. In the event of damage, 

notification to the manufacturer is required. 

12) Loading dock devices that are structurally 

damaged or have experienced a sudden loss of 

support while under load, such as might occur 

when a transport vehicle is pulled out from under 

the dock leveling device, shall be removed from 

service, inspected by a manufacturer’s authorized 

representative, and repaired or replaced as 

needed or recommended by the manufacturer 

before being placed back in service.
