the crane was in a loose central brake brake status before manipulation travel.

Because the central brake is normally closed, so only when the pressure is greater than o. 3MFa, the crane was in a loose central brake brake status before manipulation travel.
     (1) cares road. The "traveling downhill" switch to the "drive" position; then "braking, driving" electric door forklift jacks twist to "drive" the value of the stomach; steering wheel put the throttle pedal to control the speed, the crane can press the need for speed driving. Observation status ammeter readings sail when lifting, high speed current value should be <198A; low speed should be <100A.
     (2)-L slope traveling. Shangfen traveling crane manipulation procedures and level road is basically the same, but you want to switch to the forward travel control "invasion" file, you can Shangfen throttle driving. Meter readings observed running state, the current reference value is 220A.
     (3) small downhill slope. The "system power, driving" electric locks twisted into "drive" position to take; would travel control switch to the "o" position; steering wheel, hoisting sails by the inertia weight component down, foot brake pedal down control speed.
     (4) Long plant slope gradient with towel. The "braking, driving" electric locks twisted into "drive" position; would "traveling downhill" switch to the "downhill" position; would travel control switch to the "Back" (all) the location; steering wheel , travel agencies in the state uniform braking down, foot brake pedal to control the rate of decline.
