Safety features(Standard)

Static Contact Eliminate static electricity created from running of the pallets. Main Drive-Chain Contact When the Dive-Chain is broken or elongate,the conveyor will be protected. Skirting Contacts These contacts have been installed at both the top and bottom of the conveyor at the transition curve. If an object gets caught between the pallet and the skirting panel, the resultant pressure on the skirting panel will actuate one of these contacts, thereby disabling and switching off the conveyor. Handrail Inlet Contacts The handrail inlet contacts are located far beneath the head of the balustrade. The handrail entry contacts are so positioned that if there is any danger of an object becoming wedged in the handrail inlet points, a contact will actuate and switch off the conveyor. Automatic Lubrication System A central automatic lubrication system complete with a pump and proportioner can be installed to provided adequate lubrication for all chains automatically. Pallet chains broken contacts Located in the lower pallet-return truss, these contacts monitor the pallet chains for elongation, breakage or shortening of one or both of the pallet chains. When actuated, the monitoring contacts will disable and stop the conveyor's further movement.  Pallet Sag contacts Fixed at the start sections of both inclined upper and lower transition curves, it will be actuated to stop conveyor in case pallet (including pallet roller) sags more than 3mm or step broken. Phase Monitor This is a safety feature, which monitors the main power supply's phase.In the event of phase failure or phase reversal.The conveyor will be stop. Motor Overload & Overheat (Relay) This relay monitors the motor working condition. In case of motor over loaded or overheated is over 120%, the conveyor should be stopped. Comb Contacts If a foreign object is trapped between the comb and the pallets, the resulting pressing action will move comb plates backwards and actuate the safety contacts, thereby switching off the conveyor.  Pallet Gap Illumination Special green lamps in the form of fluorescent tubes,mounted on both the top and bottom of the conveyor, make the individual pallet clearly discernible and distinguishable,especially at the horizontal length. Boarding the conveyor is therefore made much easier for the young, elderly and inexperienced persons. Maintenance locking device The normal key start function will be invalid while Maintenance locking device is used. The inspection socket in up and down machine room couldn't use at the same time. Alarm buzzer The buzzer is located in up/down machine room, which can call passenger's attention during starting the conveyor. Speed Monitor with Anti-reverse Function Fixed at the bottom of brake, it is to monitor the speed of flywheel as well as to avoid reverse and will stop conveyor in case rated speed is over 120% or under 80%. Controller lift device It is located in machine room, which is convenient to lift the controller for inspection and testing the conveyor. Emergency stop buttons Emergency stop buttons have been built into operation panel at the upper and lower ends of the conveyor. As the name of the button so implies, the emergency stop buttons may be used to switch off the conveyor manually, during emergencies or even during normal condition.  Pallet reversing fences The fence is fixed at the end of step reversing point in the machine room and promotes its safe protection. Handrail anti-static roller The roller is located under the both end of the handrail in the truss. Service brake release contact This contact is fixed at both brake arm to monitor whether the brake is open or not. If the brake operates abnormal, the equipment couldn't start and buzzer will alarm.

Features (Option)

Handrail Colour Black is Normal colour. Other colour can be selected by your requirement. Pallet colour Natural colour is specified as standard colour, optional as black colour with tread surface ground.  Pallet Safety demarcation Yellow painting at 3 sides is specified as standard, optional as yellow resin at 3 sides. Traffic Light LED traffic light with fixed or movable arrow sign.   Safety Brake on Main shaft(Assistant brake) Fixed on main shaft, it will be actuated in case drive-chain is broken or speed is over 120%.As standard requirement,it shall be mounted in conveyor when rise is over 6m. It is standard feature for public service conveyor. Handrail Speed Monitor There are two detectors integrated in the handrail support rollers at both left and right sides. When one or both handrail are broken or run under speed, the system will be executed. Pallet Upthrust Contact It is fixed at upper/lower transition curves to stop conveyor in case of step upthrust. Pallet  Missing Device Two sensors are fixed at upper/lower return sections to receive pulse signals from pallet passing by and stop conveyor before missing step entering comb plate in case of pallet missing. Skirting Brush It is fixed at left/right skirting panel to cover the gap between pallet and skirting in order to avoid possible risk caused by the gap. Skirting Lighting Skirting lighting is installed in the skirting panel on both left and right sides. VVVF Energy Saving System It is a frequency inverter system to save energy up to 60%.Conveyor  will run at low speed during no load and automatically return to normal speed during load, which is activated by photocell sensors at entrance. Auto-Start The conveyor should be switched ON and OFF automatically with the use of photocell sensors/contact mats which are arranged at least 1300mm/1800mm before the comb intersection line. Directional indicators will be provided together with this option. Comb Heating System Heating system is fixed under the combs of both upper and lower entrance/exit to avoid comb freezing caused by rain and snow, especially in case of temperature circumstance below zero. Truss Heating System Heating system is fixed in truss among all service steps to avoid freezing caused by rain and snow. It shall be equipped for outdoor installation in case of temperature circumstance below zero. Outside Cladding It is not included in the standard features and it can be made of hairline ST/ST or painted steel sheet as option.
