Heinrich de Fries GmbH Heinrich de Fries GmbH, Gauss Str. 20, D-40235 Düsseldorf Heinrich De Fries GmbH will be named HADEF in the following text. Original operating- and maintenance instructions in German language. Translation in other languages is made of the German original.
“winches, lifting and pulling devices”. NOTICE! Commitment A general overhaul may only be performed by HADEF or by a specialized company, authorized by HADEF. Safety DANGER! To assess the intended use of the devices correctly, the user must carry out an Ex-zone classification.
Our delivery includes the hoist supplied beginning at its suspension and ending at the load hook and if supplied with control, the control line/hose that leads to the hoist. Further operating material, tools, load attaching devices as well as main energy supply lines must be assembled according to the valid rules and regulations.
The appropriate use of the hoists is vertical lifting and lowering of unguided loads. In combination with trolleys, loads can also be moved horizontally. DANGER! It’s only allowed to use the unit in the EX-classification which is named on the type plate; or in lower classes EX II 2G IIB c T4 or EX II 2D c 135°C EX II 2G IIB c T3 or EX II 2D c 200°C...

Check the grease level of the bearings regularly Exchange friction surfaces in time and (an exception to this are electric units - maintenance of the brakes must only be effected by HADEF). Protect the device from impact, friction, rough handling and moisture.
Special scope Use of different EX-zones is depended from the EX-classification of the unit. Find the EX-classification on its type plate. Unit classified No use in EX-classification in EX-zone 3G/D 0,20,1,21 2G/D 0,20 0,20,1,21,22 0,20,1,21,2 0,20,21,22 0,20,1,2 Explosion protection The EX classification of the unit is indicated on a separate plate, situated on the unit.

The EX-classification is mentioned on the EX-type plate on the hoist. The use of the unit is only allowed for the EX-classification mentioned on the EX-type plate or lower EX classification. Design HADEF pneumatic chain hoists, with low headroom design and pneumatic trolley Type 28/06APP, with hand-geared trolley Type 28/06APH and push travel trolley Type 28/06 APR are monorail trolleys with integrated hoisting gear.
Type 28/06APP - Table 2-10t Type 28/06APP - Table 2-15t Functions The lifting gear and motor-driven trolleys are moved by pressing the buttons on the control switch. The spring-operated brake which is integrated in the lifting motor prevents the load from being lowered automatically after releasing the control keys.

Adjusting the gauge The trolley can be adjusted to various beam flange widths. Adjustment to the relevant beam flange width “B” depends on the type and size and is to be made as follows: There are distance tubes (5) and/or washers (6) situated on the load bars (2) of the trolley.
CAUTION! The distance “X” between the wheel flanges of the trolley wheels must be for trolleys up to 3,2 t: 2-3 mm (1-1,5 mm each side) bigger and for trolleys from 4 t up: 3-5 mm (1,5-2,5 mm each side) bigger than the flange width "B" of the beam Pressure roller 6.4.1 Units with a load capacity of up to 6,3 t...

It is not allowed: pulling loose of stuck loads, dragging of loads and inclined pulling is not allowed. in explosive atmosphere, except the unit is especially modified for it and marked by an indication label In reactor containment vessels. to transport people The device is not suitable for use on stages and in studios persons must not stand under a suspended load...
The oiler enriches the air with oil. Setting of oil addition: approx. 2 drops of oil must be added per minute. NOTICE! HADEF does not assume any responsibility for damage caused by non-observance of the instructions. CAUTION! Should the unit be assembled at the customer, the maintenance unit is supplied without oil.
CAUTION! Do not use grease for lubrication of load chain. Without lubrication, manufacturer's warranty and/or liability will be void. NOTICE! Continuous, thorough lubrication will increase the life of the chain considerably. Safety check Before putting into service initially or when putting back into service, it must be checked whether: All fastening screws (if existent), socket pins, flap socket and safety devices are tightened and secured.
Servicing and maintenance work must only be done when the hoist is not loaded. Records must be kept of all test results and measures taken. 12.2 Monitoring The monitoring and servicing intervals stated are valid for operation under normal conditions and single-shift operation.
Motor output brake lining thickness B min. 0,52-0,75 1,5-2,5 Illustration 14 12.5 Overload protection If the hoist does not lift the permitted load, the overload protection must be adjusted. Adjustment may only be done by a service company, authorised by the manufacturer! DANGER! The factory setting of the overload protection is secured by a seal.
13.2 Periodic checks Independently from the regulations of the individual countries, lifting devices must be checked at least yearly by a qualified person or licensed qualified person regarding its functional safety. 13.2.1 Components to be checked The following must be checked: Dimensions of load chain, load hooks, pawls, bolts, ratchet wheels, brake linings.
