2) ⅓ for low speed and ⅔ for high speed.

3) Change of ED % from 50 to 40 results in a change of duty group from M6 to M5. For configurations with the duty classification M5 or M4, the duty group will remain unchanged if the ED % changes from 50 to 40.

3.4 Hoisting brakes

The chain hoist is equipped with a disc brake which includes a rotating disc with two friction linings.

The brake coil is energized by a DC voltage coming from the brake rectifier. The brake rectifier converts the AC voltage into a DC voltage. The rotating parts of the brake 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 allowed air gap is indicated on a sticker attached to the brake and is to be checked from there. The protection class of the brake is IP66.

The brake lining wear criteria is indicated on the sticker placed next to the measurement hole. If the brake wear has exceeded the allowed measurement criteria, contact authorized service personnel for a brake change.

3.4.1 Double brake (option)

The double brake option consist of a main brake and a secondary brake that are assembled on the same hub. During the hoisting motion, the main brake and the secondary brake are energized simultaneously from the brake board. When the hoisting motion stops, the main brake is switched off immediately, whereas the secondary brake is still energized for a few milliseconds by the motor inductive effect.

The main brake holds the first position (located ‘on the top’) in the double brake assembly, which makes the checking of the brake lining wear easier.

The secondary brake works only as a back-up brake for the main brake. It will be the functional brake only in case the main brake is damaged in such a way that it cannot hold the load. If the main brake operates normally, there is no need to check the wear on the secondary brake.

3.4.2 Manual brake release (option)

The manual brake release feature is available as an option. With the help of this feature, the brake can be released by hand in situations where there is a need to be able to lower the load manually.

The manual brake release should only be used in emergency situations where the brake cannot be released normally, since extensive use of it as well as high lowering speed can result in immediate wear-out of the brake lining. Note the warnings related to the use of the manual brake release stated below.

Important notice before starting to use the manual brake release:

WARNING

Note that extensive use and high lowering-speed can make the brake lining wear out immediately.

WARNING

Make sure that the hoist is not connected to any source of electricity, and that the electricity cannot be activated accidentally.

WARNING

No-one must stand within the danger area of the moving load. Clear and secure the danger area.

WARNING

Before using the hoist again, make sure that the manual brake release is stored safely.

How to use the manual brake release

1 Take the manual brake release lever and place it on the brake.

Insert one arm of the lever into the brake gap on the left side of the upper fixing screw.

2 Turn the manual brake release lever in a way that its second arm fits into the brake gap on the opposite side of the brake.

3 Tilt the manual brake release lever in the brake gap and push it carefully to open the brake.

Do not open the brake for more than one (1) second before stopping again.

Repeat the procedures for pushing the lever and lowering the load within short intervals.

3.5 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.

The slipping clutch construction varies according to the hoist frame size. The hoist bodies 02-05 use the same kind of clutch with just one clutch disc; whereas the bigger models, 12-25, are built with a slipping clutch with two clutch discs. An intermediate disc is placed between the two clutch discs providing the construction with altogether three friction surfaces to increase the torque.

Figure 1. The following illustration presents the clutch type used in the hoists with frame sizes 02 to 05. It contains only one clutch disc.

2-step geared limit switch

The 2-step geared limit switch works together with the internal controls as an adjustable upper and lower stop limit.

4-step geared limit switch

The 4-step geared limit switch provides, together with the internal controls, an adjustable upper and lower stop limit. Two (2) of the cams are not connected to the controls, and can thus be freely used for end-user requirements.

The operation limits for standard rotating L/S are as follows:

12 7x20 16 36 56

*NOTE: Higher heights of lift are available at request. The hoist length might increase.

3.6.5 Adjusting the geared limit switch

If the hoist is equipped with a geared limit switch, the cutting points of the limit switch need to be adjusted before starting to operate the hoist. First check the operation of the limit switch. After checking the operation of the limit switch, adjust the cutting points.

Access the geared limit switch by opening the end cover of the hoist from the brake side. Adjust the cutting points by turning the setscrews (1) ... (4) – depending on the number of the switching elements:

Turn to the left: The switching point is moved ‘downwards’ Turn to the right: The switching point is moved ‘upwards’

2-step geared limit switch 4-step geared limit switch

The setscrew 1 is the down limit and the setscrew 2 the upper limit.

The setscrews 1 and 2 are the down limit and the setscrews 3 and 4 the upper limit.

3.7 Chain reeving components

3.7.1 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.

An accurate chain positioning is achieved with the help of intermediate teeth in the chain sprocket. This means less chain wear and a longer lifetime of the chain.

3.11 Traveling motors

Three different inverter drive units are used as standard for the varying chain hoist applications.

The control inverter, type CMX 007, is mounted on the side of the unit and is connected with a plug to the chain hoist.

The TMU 2 is also available as a 2-speed motor version.

• 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

7 LOAD RANGE AND DUTY CLASSES

5.1 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 =

Operated continually at medium loads and frequently at maximum loads.

L4 Very heavy

Operated regularly at maximum and at almost maximum loads.
