Elevator Control

Description

We inspect and maintain your elevator in optimal condition to minimize risks as much as possible. Below, we outline what we consider during inspection: 1. Mechanical Safety Locks (The "Ratchet") This is the most important and noisiest system. If you have ever heard a "click-click-click" sound while the elevator is ascending, those are the safety locks. 2. Synchronization System (Steel Cables) In two-post lifts, the greatest danger is not only that the vehicle might fall, but also that one side descends faster than the other, causing the vehicle to tip over. Equalizing cables: These are not the cables that lift the load (that function is performed by the piston), but rather they connect both carriages to ensure they ascend and descend at exactly the same time. Tension control: If a cable becomes excessively slack, many modern control panels detect the loss of tension and immediately shut down the motor to prevent dangerous tilting. 3. Hydraulic Safety Valves Within the hydraulic oil control system, there exist special valves known as parachute valves or flow limiters. Immediate action: If abnormally rapid oil flow is detected (such as would occur if a hose bursts), the valve closes via differential pressure. Result: The elevator stops abruptly or descends at an extremely slow speed, giving the operator time to react. 4. The Control Panel's "Brain" The control panel you provide is responsible for electronically managing all these functions: Emergency Stop Button: Instantly cuts off all power. Limit Switches: Sensors that stop the motor if the vehicle ascends too far (preventing the vehicle's roof from colliding with the upper beam). Thermal Protection: Prevents the motor from overheating and losing power while holding the load.
