There are two series of backup battery unit: 1, series GTB; it is designed for controlling constant voltage; 2, series GTBT. It has functions of magnetism sustaining as well as magnetism regulating in case of power-cut and it can regulate the numbers of plates to be attracted through regulate the field voltage of magent freely.These series are improved type which replaced series GTB6 and LPB1 and their reliability and technical advantages got improved. And at the same time maintenance get reduced largly.
Main Features
1. It will auto shift power supply in case of sudden failure during operation. The attached materials will be guaranteed not to fall down during its sustaining time, and thus ensure the material be place down safely through the brake of windlass.
2. The unit is equipped with full set such as charging device and disply testing and alarm-giving system.
3. Valve-controlled, full-sealed plumbic acid batteries which asks for no maintenance, no employee around when charging, shift charging mode automatically through self-monitoring and a long service life are adopted.
4. The unit is light and compact. There is no special requirement on installation; easy and convenient in maintenance and service.
5. The unit which has great expansibility has all kinds of interlockers and many control modes to meet your demand such as drivingroom control, remote control, centralized control, etc.
Note for Model Selection
1. Rated voltage of the electromagnet shall match output voltage of the equipment; the total current amount (power consumption) in cold state of the electromagnet shall be less than or equal to the output current (power) of the cabinet.
2. The brake of windlass matched with the cabinet must use DC brake and a matched inverter should be adopted when the coil at brake of windlass is AC.
3. Working temperature is over 40°C . or other special requirements such as modification, capacity enlargement, etc. please state clearly when place an order.

Main technical data
Corollary equipment & overall dimension (for reference)
Note: The thickness of cabinet is increased by 50 mm (both D and Y are increased); An extra 50mm along forward & backward at the top are added. An inverter is needed when the crane hook is AC brake. And because power of AC brake is different, the cabinet will be varied as well. Please contact us for final confirmation, this type is for outdoor use.
GTBT Magnetism regulating & sustaining equipment
Main technical dat
Corollary equipment & overall dimension (for reference)
Note: For outdoor type, add an extra 50 mm at the thickness of cabinet , 30mm at the width of the top and 50mm along both forward and backward direction;there’s no rectification transformer if the control cabinet belongs to improved type. Rated voltage of the magnet should match with output voltage of cabinet and magnet power in cold-state shall be less than rated output power of cabinet. If ambient temperature of the cabinet is over 40°C please state clearly when place an order. The figs. in the bracket refers to dimension of the improved type.
