4.6 INFORMATION WHICH SHOULD BE EXCHANGED BETWEEN THE USER AND THE DESIGNER OR SUPPLIER
As chain lever hoists are frequently used for miscellaneous lifting purposes, precise details of the load to be lifted are not always available. In these circumstances, only a general specification can be given and this should include the following information:
Intended application e.g. lifting, tensioning or pulling.
The maximum load to be lifted or SWL
Details of the application that may have a bearing on the load to be lifted, e.g. wind, hoisting out of water, etc.
The maximum extended dimension.
The maximum acceptable drawn up dimension if headroom is important.
The range of lift.
The type of chain required.
The conditions of service and in particular any conditions which the user suspects might be hazardous, e.g. extremes of temperature, high probability of shock loading, uncertainty of weight of load.
