LSH-BE LIFT SYSTEM HEAVY WITH BOX ENCLOSURE INTEGRATION CONSIDERATIONS General Mitigations: • Implement a hold to run/dead man switch operation. • Control methods should be located within direct line of site of the mechanism. High Risk - Crushing • Implement password or key switch protected operation. Top Panel Crush hazard between the base panel and the cabinet top as the lift closes. Mitigation Install a pressure switch below the top panel to detect any obstructions. A pressure switch can be installed between two timber panels to allow the vertical movement required for switching. Box Enclosure Low Risk - Falling Objects Falling object hazard if objects are left on top of the top panel. Low Risk - Crushing Crush hazard at the cabinet aperture when Mitigation mechanism is opening. Install a light curtain in front and behind the mechanism to create an exclusion zone. Mitigation Base Panel Keep the gaps between the cabinet aperture and the moving panels to a minimum (no smaller than 3mm [1/8”]) to reduce the risk of obstruction. Install a pressure switch below the cabinet top to detect any obstructions. Low Risk - Crushing Cables could be snagged if not properly managed High Risk - Crushing through and around the mechanism, causing Crush hazard below the mechanism when damage to the mechanism and electronics. mechanism is closing. Mitigation Mitigation Ensure sufficient cable slack is allowed around Ensure area below the mechanism is kept clear movement joints to prevent stretching and/ or at all times when the mechanism is being used. damage to the cables and/ or mechanism. If installing or maintaining the mechanism do so with the mechanism turned off. CONSIDERATIONS SHEET UK +44 (0) 1438 833577 US +1 (603) 742 9181 ISSUE 001 WWW NET . . SHEET 1 FUTUREAUTOMATION
