Electric Gantry Crane safety design specifications:
Electric Gantry Crane with an emergency power-off switch, in case of emergency, you can cut off the crane total power, the switch is located in the power distribution cabinet.
Motor is equipped with fully functional protection device, overcurrent, short circuit fault of the motor can be effectively protected.
Electric Gantry Crane has zero protection, when the mechanism prepared to operate or power is restored, the controller must first be placed in the zero position, then press the start button, the motors of all mechanisms can start.
Overload limiters: Electric Gantry Crane with overload limiters, when load reaches 90% of rated, the display device will automatically alarm; when the load reaches 105% of rated, the crane will automatically cut off the power supply of hoisting mechanism.
Rising limit position protection device: hook lifting mechanism with limit device, when hoisting to a limit position, automatically cut off the lifting power supply.
Stroke limiter: both sides of Electric Gantry Crane and trolley traveling mechanism are equipped with stroke limiter, it will automatically cut off power when crane and trolley traveling to the limit position, then they can traveling in the opposite direction.
Electric Gantry Hoist equipped with lost pressure and zero protection; the driver can make emergency power off in a convenient operation place.
Door of driver’s cabin and bridge frame has electrical interlock protection device.
In Electric Gantry Crane legs there has sound and light warning, emergency stop button box and crane rail clamp.
For the crane lifting height exceeds 30m, install anemometer and lightning rod on the top.
For the wild use gantry crane, with open around and no high-rise buildings, also set up lightning protection device.
For gantry crane span more than 40m, it will be taken synchronized or track deviation correction measures.
