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. -
Page 5: Appropriate Use
Before starting work, the operating personnel must have read the operating and installation instructions, especially the chapter "Safety Instructions". This is especially important for operating personnel that rarely uses the equipment, i.e. for installation or maintenance work. DANGER! In order to avoid severe injury, please pay attention to the following when using the equipment: ... - Page 6 The equipment is to be used exclusively for movement of goods. Under no circumstances my persons be moved. Never load the devices beyond their working load limit. Pay attention to the accident prevention regulations (UVV). Should the hoist be used outside of Germany, please pay attention to the national regulations that apply. ...

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. - Page 8 Example of ATEX classification: G Ex h CE-marking European Union explosion-proof operating material danger of mine damp device group / application other areas prone to explosion for use in zone 0 device category for use in zone 1 for use in zone 2 ...caused by gas, steam, fog EX atmosphere ...caused by dust...
- Page 9 DANGER! The maximum surface temperature of the equipment must always be lower than the ignition temperature of the gas/vapour/dust/air mixture. Equipment which has been classified in higher temperature classes is, of course, also approved for use in applications with lower temperature classes.

Page 12: Design
Design HADEF Spur Gear Hoists of compact design are monorail trolleys combined with manual hoists. With monorail push travel trolley or with monorail hand geared trolley Operation by hand through hand chain. Illustration 3 Functions The load is lifted or lowered by pulling one of the chain falls of the endless hand chain of the hoist. A load pressure brake prevents automatic lowering of the load after releasing the hand chain. -

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. -
Page 16: Load Chain
Load chain Before commissioning the load chain must be aligned and oiled. 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. NOTICE! Continuous, thorough lubrication will increase the life of the chain considerably. -
Page 17: Replacing The Load Chain
11.3 Replacing the load chain VORSICHT! 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. -
Page 18: Checking The Load Chain
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. -
Page 19: Checking - Pawl
CAUTION! When the dimension of hook opening width is deformed more than 10% or when the dimension of the hook bottom thickness is fallen short of by 5% due to wear, the hook must be replaced. DANGER! In case of corrosion and/or wear of the surface coating, the hooks must be exchanged by original hooks or the coating must be renewed. -
Page 20: Pulleys
Wash dirty chain with petroleum or a similar cleaner, under no circumstances heat the chain. If there are environmental influences that foster wear, such as sand, a dry lubricant should be used, e.g. graphite powder. When lubricating the chain’s condition of wear should be checked. Recommendation Interval oil for example: FUCHS RENOLIN PG 220... -
Page 21: Gear Spring Pressure Brake
13.6 Gear spring pressure brake During the check, brake lining wear is verified. The brake linings must be replaced when the wear limit is already reached at one position of the lining, - as this can be the case when wear of the linings is irregular. CAUTION! The brake linings must be free from fracture. -
