8.17 General overhaul GO

NOTE

During the general overhaul the following parts must be replaced in addition

to the checks and work specified in the inspection and maintenance schedule

(see table 1).

• Gear wheels of the gearbox

• Gearbox bearings

• Motor shaft

• Motor bearings

• Connecting elements

• Gear oil

The theoretical duration of service D (hours at full load h) depends on the Group of

Mechanisms classification of the D-SH (see section 9, table 3).

The owner must arrange for a GO general overhaul to be carried out when 90% of

the theoretical duration of service has elapsed. A general overhaul must be carried

out no later than when the end of the theoretical duration of service is reached.

The small parts (screws, washers ...) to be replaced during maintenance and as-

sembly work are not listed separately.

The general overhaul carried out by the manufacturer or an authorized specialist

company fulfills the condition for continued operation of the D-SH hoist.

Thus the provisions of the relevant accident prevention regulations and BGV D8

are satisfied.

Further utilization is approved when an expert engineer has certified that the con-

ditions for further utilization have been met. Completion of the general overhaul

must be confirmed and a further period of utilization in accordance with FEM 9.755

must be entered.

Upon reaching the theoretical duration of service, the owner is obliged to carry out

a general overhaul (see “Regular inspections”, section 2.8).
