When the vehicle approaches the parking spot, the system would decelerate automatically.
◆ Stop of drive unit and return unit
When the vehicle arrives at the parking spot, the system stops automatically.
◆ Over travel of drive unit and return unit
When the vehicle travels over the parking spot without stopping, the protection would start and the vehicle is stopped immediately.
◆ Smart protection for curves
The vehicle will slow down before entering the curve, run through the curve slowly and then accelerate to the designed operating speed. (Only available for frequency conversion and hydraulic speed adjustment.)
◆ Speed protection
When the towing vehicle runs over speed or slips, it will be stopped immediately by the speed protection.
◆ Brake failure protection
The brake has to be released/non-braking before the motor starts, otherwise the motor cannot be started.
◆ Alarm for rope falling at down grade-change point
If the rope falls off the rope-carrying pulley before the system starts, the electrical system will send alarm and the system cannot be started. If the rope falls off the rope-carrying pulley during the system operation, the electrical system will send alarm and the system will stop automatically.
◆ Anti-rope-falling at down grade-change point
The rope could fall off the rope-pressing pulley in waved roadway with changeable grades and heavy load and affect the safe operation of the system. The anti-rope-falling at down grade-change point is simply structured with reliable operation, which effectively prevents the rope from falling off the rope-pressing pulley.
◆ Tensioning limit
The tensioning device is divided into mechanical tensioning and hydraulic tensioning. The tensioning limit protection covers weight lower limit and travel limit of oil tank.
◆ Lower limit of weight
When the tensioning weight falls off the ground due to that the pulling rope or tensioning rope becomes loose, the pulling rope would lose constant tension and the system could not operate safely and will stop automatically.
