Port or harbor portal crane is used for loading and discharging cargos from ships or shipbuilding. It is suitable for various ports and shipyards with hook, hanger, grab, container spreader etc. Portal Jib crane is also called mobile slewing and luffing crane due to its working features.
Features:
1. Power source is three-phase alternating current, rated frequency is 50HZ, rated voltage is 380V.
2. The temperature in the working environment should be in the scope of -20°C~+45°C and the relative humidity is no higher than 95%(with dew).
3. In-service, the wind speed should be no higher than 20 m/s; and out-of service, the wind speed should be (35-42) m/s.
4. The installation of the crane rail should accord with requirement of Jt5022.

- Q:How much cable does the construction elevator 44KVA need?
- 44 kva should choose 16 + 2 * 3 * 6 square cable, 16 of the 30 ℃ safe carrying capacity is 78 a cable Current I = P/U / 1.732 = 44000/380/1.732 is approximately 67A The construction elevator will not only carry the engineering materials but also the higher frequency, the load calculation will be calculated according to the continuous working system. The cable should be used for the YGTZ special cable.
- Q:Can construction elevators be taken by people or by goods
- The construction elevator can be taken either by person or by cargo Material hoist (dragon door frame, well frame) can be carried only, not by person
- Q:Do the elevator need to be installed when the main project is in construction
- In the construction of the main body, the construction elevator should be installed. The general construction is about 15 meters. The construction elevator is commonly called the construction elevator, but the construction elevator includes a broader definition and the construction platform belongs to the construction elevator series. Simple construction elevator is by car, driving mechanism, standard section, attached to the wall, chassis, fence, electrical system and so on several parts, manned cargo construction machinery is a frequently used in construction, because of its unique enclosure structure make it take up both comfort and safety, construction elevator is usually used with tower crane on the construction site, the average load in 1-3 tons, running speed is 1 to 60 m/min. The construction elevator of our country is more and more mature, and gradually goes to the international. 3, building main body engineering means based on the above foundation, accept, for all the top load and construction project, maintaining structural integrity, stability and safety of bearing structure system.
- Q:Gear rack driven
- Driven by two or three worm gear reducers, the ladder cage is a load bearing unit, and gravity is carried by a rack. At rest, the force point is in the meshing of the gear and rack.
- Q:What is the main function of the construction elevator safety guard
- For safety device of construction hoist main effect is in the process of elevator used in times of emergency power, hit the brakes, let hoisting cage security attached on the guide rail frame, prevent the hoisting cage falling!
- Q:Excuse me: what is the meaning of heavy weight in the construction elevator?
- With double cage for heavy, namely SCD200/200 series Is the two cages, each cage has a corresponding weight, the weight up and down in the elevator cage rise to energy conservation and reduce the reaction between the up and down, when you imagine front-rear door principle is about the same
- Q:A lift motor is 7.5 KW, and the frequency converter sends current 4.2 A, which has A heating resistance in the converter, and how the charge is calculated when the lift is full. Or consider the power of the converter and the power of the thermal resistance.
- The full load is 7.5 KW. The output current is 4.2 A, is the converter 7.5 KW?
- Q:The construction elevator always jumps
- The construction elevator of our construction site always jump at the start of the building, always can't find the reason, the reason that can be so, have a person encounter this thing But it used to be normal, and sometimes it's jump, start, jump, start, and sometimes you can do it over and over again,
- Q:When building tall buildings, the machine that USES to lift concrete to wait for tall building
- It should be the ground pump, the center is the tower crane, the construction face is the concrete pump of the cloth machine to the construction method. The advanced cloth machine is the arm bracket of the pump car, can operate with the remote control, is as convenient as the pump car.
- Q:The difference between the derrick and the construction elevator?
- Derrick is with the hoist rope hoisting, referred to as goods for SSB100 type, with construction lifter model does not allow the manned, deadweight is one tons, construction lifter is said cargo amphibious ladder, with gear and rack driving, weight is 2 tons, you can have a look at the GB/T 10054-2005, the construction lifter, with clear rules.
