6.3 IMPORTANT GUIDELINES
6.3.1 General
6.3.2 Risk assessment by the installer
• The DHOLLANDIA column lifts consist of a wide range of different executions and are offered with a multitude of options to adapt
the liftgate to the client’s specific needs. They are installed on a wide variety of different vehicles, often personalized by the body
builder. Moreover, they are being used for an endless array of vastly different applications often unknown to the manufacturer.
• It is therefore important that the installer conducts a comprehensive risk assessment to make sure the liftgate complies with the
applicable legislation and can be used safely. SECTION 7 of the operation manual gives a good overview of the applicable risks that
must be mitigated. DHOLLANDIA strongly recommends implying the client and his H&S management in the risk assessment process
to obtain best possible understanding of the application and work conditions.
• In K9 executions travelling above the vehicle floor (see 6.4 on page 13), the user and occasional bystander is exposed to additional
risks, and a thorough risk assessment is required.
6.4 ADDITIONAL GUIDELINES FOR LIFTGATES TRAVELING ABOVE VEHICLE FLOOR LEVEL
6.4.1 Guard rails
• Guard rails MUST be fitted in all applications where a significant risk exists that the operator could fall off the platform and suffer
bodily injury. 49 C.F.R. § 571.403 S6.4.9.2 states - privately operated lifts do not require guard rails but must follow S6.4.9.3 →
S6.4.9.9 if equipped with guard rails.
• Some type of guard rails have a significant impact on the geometry and construction of the column lift. Only a limited number of types
of guard rails can be retrofitted.
• Therefore, DHOLLANDIA strongly recommends to include the risk of falling in the early stages of the installer’s risk assessment and
project development. The installer MUST check and abide by local and federal regulations when considering these risks.
• Falling from heights can cause serious bodily injury or death.
• Therefore, guard rails MUST be foreseen in all applications where a significant risks exists that the operator
could fall off the platform and in accordance with 49 C.F.R. § 571.403 S6.4.9.2.
• ALWAYS make sure that the lift columns are installed in accordance with the installation instructions of DHOLLANDIA.
• Pay special attention to the type of bolts, minimum quantity per side, minimum size and strength class, and the spread of the bolts
over the full surface of the columns. Fasten the bolts and nuts with the required torque, see 16.2 on page 43.
• Incorrect or negligent installation can cause the liftgate to fall off the vehicle chassis once the platform is loaded, and can put the
installers, the operators, and bystanders at great risk of bodily injury or death.
• In case of doubt, don’t continue, but contact your national DHOLLANDIA dealer for further advice.
• DHOLLANDIA liftgates are installed on a wide variety of different vehicles and are being used for many different applications often
unknown to the manufacturer.
• To guarantee the safe use of the liftgate in all foreseeable circumstances, ALWAYS conduct a thorough risk analysis. SECTION
7 of the operation manual provides a comprehensive overview of the main risks potentially associated with the liftgate use.
