25、he load or attachment can restrict visibility.To provide this information to the operator, the manufacturer should choose one of the methods described in Annex A or an equivalent method.12 BS EN 16842-2:2018EN 16842-2:2018 (E)Annex A (informative) Information for operator visibility during useA.1 Ge
26、neralThis annex describes two alternative methods provided as information for use which can be included in an operators handbook, to enable the operator to evaluate the visibility on counterbalance trucks when laden.Obstructed visibility can be caused by the dimensions and/or shape of a load on the
27、fork arms or the attachment on the truck, the operators visibility can be insufficient for safe operation. As part of the operational assessment for the truck the user may specify the operators visibility requirements for operating with a laden truck under the user specific circumstances.In addition
28、 to user specific circumstances, the following estimations can assist the user to determine when driving in the forward direction with a laden truck that the visibility is sufficient, in case of doubt the operator may drive backwards.The manufacturer may provide a statement that the user may analyse
29、 all risks associated to reduced visibility and balance the actions between the different hazards which can include: the insufficient visibility, caused by the load dimensions;and the potential adverse effects on the operator (rotation and/or sideway bending of the body).NOTE Driving backwards with
30、industrial trucks normally requires a rotated operators body position, which isnt ergonomic over a long period of time.For less potential adverse effects on the operator, the manufacturer may offer several options, e.g.: comfort seats with air suspension; seats with arm rest; rotatable operators sea
31、t and/or operating position; special-designed trucks, e.g. for beverage industry.Otherwise, the user may optimize the logistic process to minimize any potential hazards by, e.g.: correct adjustment of the seat to the operators mass; splitting of loads with large dimensions; optimizing of transport r
32、outes; sufficient breaks for operator or alternate operators on the truck during one shift; additional personnel to assist the operator.Methods 1 or 2 can assist the user and/or the operator in determining the correct procedure for transporting loads when visibility is reduced by the height of the l
