3 Selection criteria The size of the hoist is determined by the load spectrum, average operating time per working day, SWL and reeving.. What are the operating conditions? 2. What is the specified safe working load? 3. To what height must the load be lifted? 4. What is the required lifting speed?. Do the loads need to be lifted and lowered with high precision? 6. Is horizontal load travel necessary? 7. How is the hoist to be controlled? The load spectrum (in most cases estimated) can be evaluated in accordance with the following definitions: The group is determined from the operating time and load spectrum Load spectrum Average operating time per day in hours Light Hoist units which are usually subject to very small loads and in exceptional cases only to maximum loads. SWL Small partial load Small dead load Operating time 2 Medium Hoist units which are usually subject to small loads but rather often to maximum loads.
