Product Description
Product Description
3~5T A3 LZ type single beam grab crane for factory single girder overhead travelling crane
LZ grab bridge crane is based on LDA and travels with the grab bucket through a wire rope hoist or a hoist trolley.Cranes generally work indoors, and the working environment temperature is -20ºC~50ºC.The grab can be customized according to customer needs. The split electro-hydraulic grab can be used in water.
The relative humidity of the air does not exceed 85%. The crane adopts a single main beam structure, and uses an electric hoist as a lifting mechanism, which is suspended on the lower edge of the main beam for lateral movement.
Ground operation adopts squirrel cage motor with self-contained plane brake. Conical winding brake motor is used when operating in the cab. The brake is a conical brake. The reducer adopts one-open and one-close or one-open and two-close involute gear deceleration. Device.)
LDZ type electric overhead single girder grab crane is a light lifting equipment with the lifting mechanism of electric grab,and it can travel on the rails with suitable structure,the whole crane has strong rigidity.
This type crane sit on the tall concrete pillars or mental supports,its shape looks like a bridge.Single girder overhead crane runs longitudinally along the rails laid on the elevated on the both sides.This is able enough to lift materials under the bridge without being hindered by the ground cargo.Single girder overhead crane is one of the most used and largest number of lifting machinery.
Product Features
- Here are two mechanism for grab, one is for lifting, the other is for grab open and close.
- Strong box type steel structure.
- Full safety system as follows: . Weight overload protection . Emergency stop system. Over current protection. Short-circuit protection. Phase sequence protection . Zero position protection. Voltage loss protection
- Limit switch and stopper for crane long traveling and cross traveling
- Lifting overhigh and overlow limit switch
- Six direction movement
Safety System
1. Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible
2. Long and cross travel limited by means of preliminary and final limit switches or Wireless anti-collision device
3. Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling
4. All movements can be switched off by actuating the emergency-off switch at the control station via a main contact
5. High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to prevent over traveling
6. Safety hook latch used for avoiding the lifted material out off from the hook
7. Audible and visual alarm device to inform the person stay near by the travelling crane.
8. Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism
9. Protective earth conductor is fitted as standard
10. Voltage lower protection system
11. Current overload protection system
