2.2 Gear

2.2.1 Hoisting gear The hoisting gear of the chain hoist has two or three helical steps. It is specially developed for hoisting appliances. The gear is lubricated with oil in a way that will last for the designed working period of the hoist.

2.4 Hoisting brakes The chain hoist is equipped with a disc brake. There is one rotating disc with two lining surfaces. The brake coil is energized by DC voltage coming from brake rectifier. The brake rectifier converts AC voltage into DC voltage. The protection class is IP66. Rotating parts are not enclosed to ensure the self cleaning function. The brake will last for the designed working period of the hoist. Its air gap can easily be checked at the brake coil, through an inspection hole. The maximum possible air gap is indicated on a sticker attached to the brake. Brake lining criteria is indicated in the sticker placed next to the measurement hole. In case the brake has worn more than the maximum criteria, contact authorized service personnel for brake change.

2.5 Overload device: Slipping clutch The overload protection of the unit is ensured through a direct acting limiter of slipping clutch type. The device meets the requirements of EN14492-2 for such units. It is set in a way that allows the unit to lift a load corresponding to the dynamic test load (110% of SWL) and prevents the unit from lifting a load of 160% of SWL. The construction enables the brake to hold the load without any interaction with the clutch.

2.6 Chain reeving components

2.6.1 Chain drive The chain hoist units are fitted with a special patented chain drive which includes additional supporting teeth on the sprocket. Those teeth improve the support of the chain and therefore reduce the stresses and the wear. Accurate chain positioning because of the intermediate teeth in the chain sprocket. This will mean less chain wear and a longer lifetime of the chain.

4 Chain• To extend chain lifetime, lubrication is recommended.• Lubrication interval varies from month to one year depending on usage.• Lubrication shall be done before signs of corrosion or dryness.• Lubricate the chain with suitable lubrication. Lubricant for chain shall be water

resistant, non-adhesive, transparent thin oil, which is able to penetrate.• Only lubricate the chain lightly, excessive lubrication may cause dribbling


Mobil Gear 632 As required

2 Hoisting Transmission• Lubricated with oil. Lubrication will last for the designed working period of the

6 LOAD RANGE AND DUTY CLASSES

6.1 Hoist classifications The mechanism group – M4, M5 or M6 – of an electric chain hoist depends on operating time per working day and on the class of load spectrum.

The hoist operating time (Ot) can be calculated by using following formula:

Actual load spectrum factor can be calculated using following table:

Load % Lifting time % Factor k3 Load spectrum factor 100 % * 1 =

+ 80 % * 0.51 =

+ 60 % * 0.22 =

+ 40 % * 0.06 =

+ 20 % * 0.01 =

+ 0 % * 0 =

= Sum: 100 % Sum:

Divide by 100: /100 = Load spectrum factor, Km:

Class of load spectrum Load spectrum km

L1 Km ≤ 0,125 L2 0,125 < Km ≤ 0,250 L3 0,250 < Km ≤ 0,500 L4 0,500 < Km ≤ 1



Class of load spectrums:

L1 Light

Mainly operated at very low loads and in exceptional cases at maximum loads.

L2 Medium

Operated continually at low loads and frequently at maximum loads.

L3 Heavy Operated continually at medium loads and frequently at maximum loads.

L4 Very heavy Operated regularly at maximum and at almost maximum loads.

Load spectrum Average operating time per working day [hrs] L1 Light ≤ 2 ≤ 4 4 - 8 8 - 16 L2 Medium ≤ 1 ≤ 2 2 - 4 4 - 8 L3 Heavy ≤ 0,5 ≤ 1 1 - 2 2 - 4 L4 Very heavy ≤ 0,25 ≤ 0,5 0,5 - 1 1 - 2
