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.
Failure to follow the instructions of this manual can lead to unpredictable hazards. For any resulting damage or personal injury, HADEF assumes no liability. The unit was designed and built following a risk analysis and careful selection of the harmonized standards that are to be complied with, as well as other technical specifications.
Requirements for the operating personnel The units may only be operated by qualified persons that are appropriately trained and that are familiar with it. They must have their employer’s authorization for operation of the units. Before starting work, the operating personnel must have read the operating and installation instructions, especially the chapter "Safety Instructions".
Supporting structures and load-attached devices used in conjunction with this equipment must provide an adequate safety factor to handle the rated load plus the weight of the equipment. In case of doubt, consult a structural engineer. If the equipment has not been used for a period of time, carry out visual checks of all main components such as chains, load hooks etc.
Safety device for transport NOTICE! Should a safety device for transport exist, please remove it before commissioning. Storage Store the equipment at a clean and dry place. Protect the equipment against dirt, humidity and damage by an appropriate cover. Protect hooks, wire ropes, chains and brakes against corrosion. Description Areas of application The devices must be as far as possible installed in a covered room.
case of ex p roof hoists, t the housing i is only made e of steel plat tes. Load chain ccording to E EN 818-7-T h igh quality c hain. All com mponents ma atch precisely y to each oth her.
NOTICE! For double lifting mechanism Operate both lifting mechanism, synchronous resp.evenly. CAUTION! Run in of chain into the chain container for hoist with double lifting mechanism For a correct run in of chain into both chain containers, the lowering operation must be carried out, without load, at certain intervals, until both chain container are empty.
Load chain Before commissioning the load chain must be aligned and oiled. For the first commissioning of motorized hoists, chain oil is supplied with the delivery. Move safety note and fixing wire away from the chain. CAUTION! Do not use grease for lubrication of load chain. Without lubrication, manufacturer's warranty and/or liability will be void.
11.3 Replacing the load chain CAUTION! If there is any visible damage and when the conditions for replacement are reached (i.e. one or several dimensions in the table have been reached, there is corrosion or elongation), the chain must be replaced. When replacing the chain, also check the chain wheels.
12.2 Checking the load chain CAUTION! The load chain must be tested over its entire length! The measure of the load chain must be carried out especially in the areas which are subject to the highest wear. Through the lifting movement, these are the contact points of the chain with sprocket wheel and deflection pulleys.
Recommendation Interval oil for example: FUCHS RENOLIN PG 220 or special chain lubricant Load chain 0,2 l 3 month Use NO grease! CAUTION! Do not use grease for lubrication of load chain. Without lubrication, manufacturer's warranty and/or liability will be void. 13.2 Pulleys Recommendation...
