Catalog size values follow the original rated-capacity column. Confirm the intended load movement and rope arrangement with the selected size.
For a manually operated pulling or positioning installation, supply the load movement, working travel, and base arrangement. If the task involves lifting or holding a load, specify that duty for a model and brake review.
The drawing lists a handle radius R of 180 mm for 600–1,400 lb sizes and 251 mm for 2,000–2,500 lb sizes. Allow for the handle sweep and operator access. State the required rope diameter and length when requesting the assembled configuration.
