Table 3-6 Wear values suspension parts
If hook or eyebolt shows damage, cracks, deformation or corrosion, it must be replaced. If the prescribed dimensions (min.
/ max.) no longer comply with table 3-6 and figure 3-3, the parts must also be replaced. The hook safety catch must be fully
functional and fully closed, replace if necessary.

3.2.9 Suspension parts
All statically loaded parts are considered to be suspension parts. The bearing surfaces of the slewing suspension parts must be
periodically greased. Torque values for screws of strength class 8.8 per DIN ISO 898:
3.2.8 Slipping clutch
The slipping clutch is set to 125% at the factory and reliably prevents overloading of the chain hoist (the power limiting factor per DIN EN
14492-2 is Φ
DAL
= 1.6). In the case of the two lowest lifting capacities in tables 5-1 to 5-5, the factor is ≤ 2. The resultant forces arising from
the adjustment of the slipping clutch must be able to be absorbed by the suspension parts. The coating is wear resistant.
Adjustment and testing of the slipping clutch may only be carried out by authorised personnel and must be recorded in the
inspection pass. If the nominal load is no longer lifted, or there is delay in achieving the lifting speed, the slipping clutch must
be adjusted.
3.2.7 Transmission
The transmission has permanent lubrication.
The housing of the transmission may not be opened.
3.2.6 Limit stop
Check screw fittings at the limit stop and single fall hook clamp and tighten with the correct torque if necessary. See chapter 3.2.9 for
guide values.
3.2.5 Chain guidance
The inlet openings of the chain are visually inspected.
• Provision only with model LPML 250: screw tightening torque for two-part chain guidance 1.5 Nm.
• A damaged wear plate at the bottom of the housing must be replaced.
