Product Description:

Introduction:

Our SC Construction Hoist is an industrial engineering elevator driven with pinion and rack, used for vertical transportation of materials, people and other heavy items, applicable to highrise building construction, storehouse, port, dock, tower, chimney and so on.


Features:

1. Adopts the most advanced VF speed control device and microcomputer programmable logic controller.

2. Stepless speed control helps eliminate the concussion during start up and braking, steady the operation process,and ensures automated leveling.

3. Adopts open loop V/Fcontrol; the speed control precision can reach ±2~3%. Realizes accurate low speed positioning of the hoist and avoid slipping during downward stopping of hoist.

4. The VF system has current-restriction function, ensuring a small current when motor start up and reducing the concussion to power supply. It reduces the engery consumption and mitigates effects to on site electric equipments.

5. The steadiness during running mitigates concussion to mechanical parts, reduces wears of rack, pinion and the brake and prolongs the spare parts'life.  

6. The VF system also has the over voltage protection,low voltage protection, overcurrent, overload and anti-stalling protection functions,

7. The system applies the special software for hoists developed by our company, making the operation more safe and reliable.


Specifications:

Recommended cage dimension (LXWXH): 2.0X1.0X2.5, 2.5X1.0X2.5, 2.5X1.3X2.5, 3.0X1.5X2.5, 3.2X1.5X2.5, 3.8X1.5X2.5, 4.0X1.5X2.5, 4.2X1.5X2.5 etc

Q:How many guides are in the construction elevator
1 guide frame is 1508cm, the highest can be 400 meters
Q:How does the elevator operate
One must first understand the basic structure of the elevator, function, operation and safety protection measures for each elevator, so each new elevator operation need to carefully look at elevator operation manual! 2 each elevator switches in eye-catching position, the first thing to know to control the power box, and stop buttons and effective protection switch, it is helpful for you in the process of operation, have safety emergency measures! 3 each elevator has the control box, it has indicated the direction and floor indicator, if your operation is simple and easy lift, it is not a lot of protection measures, only up to the threshold, sometimes may malfunction, press in operation had better stop, make sure someone wrong operation or accident happen! 4 as for how to increase the security of the original equipment and measures, can reach Ann and suzhou mechanical and electrical technology department contact, they have free professional technical support and solutions!
Q:How does the construction lift fall without electricity
Pull the manual release (or pedal release) to loosen the electric motor to loosen the brake, the lift will fall, and the speed localizer will die. It's not that professionals don't try "very dangerous"
Q:Safe use of construction elevator
In the case of passenger and carriage, the loading shall be uniformly distributed, and the overload shall be strictly prohibited. When the elevator runs to the top and lowest levels, it is strictly forbidden to stop at the collision or lower limit. 7. The driver for leaving hanging basket and while going off work, should be hanging basket fell to the ground, to cut off the total power supply, and the door is locked point, prevent other undocumented workers start the hoisting cage without authorization. Wind up above 6, should stop using the elevator and bring the cage down to the ground. There must be good protection on both sides of the transportation channel. Floor door should be in a normally closed state, its height should conform to the requirements of the specification, anyone shall not open or head out of the door, when the floor door open, the driver shall not start the elevator. Ensure that the communication device is in good condition and the driver should be able to start the lift after confirming the signal. The driver should immediately execute any emergency stop signal on the floor of the operation. The elevator should be installed on a separate ground protection and lightning protection device. It is strictly forbidden to do maintenance work under the condition of the elevator. If maintenance is required, the power supply must be cut off and the sign of "check in, shut off" will be hung in a prominent place.
Q:Does the new approach builder need a localizer test report
Need, not for safety device testing qualified report, inspection agency will not issue the inspection report, in the construction of elevator installation supervision and inspection report, there is a specifically for, for safety device must have testing qualified report, to be certified.
Q:How to adjust the weight limit of the construction elevator
You're not going to be without a master You still look at the instructions
Q:How is the construction elevator installed
The construction elevator should choose a good position first, do the elevator foundation, at the same time make the wall in the setting process. This one has the corresponding elevator basic drawing, should the professional personnel carry on setting up and disassembling.
Q:What is the main function of elevator motherboard?
A control system includes light, machine, electric, calculate, calculate the mainboard is mainly responsible for, the equivalent of the human brain, it gathers the elevator running status, corresponding analog signal output, control of elevator running properly and safely.
Q:What are the requirements for the construction elevator
The anti-drop safety device is an important part of the construction elevator, which can be relied on to eliminate the occurrence of the fall accident and guarantee the safety of the crew. So for safety device factory test is very strict, before delivery by the statutory inspection unit for torque measurement, critical speed measurement, measuring the amount of spring compression, each with the test report, after assembly to the construction lifter for drop test under rated load, and the site to use the elevator must be every three months to conduct a drop test. For safety device to the factory for two years for safety device (delivery date), must also be sent to the statutory inspection unit to carry on the test, after testing once a year. So far few inspection, some sites even once every three months to detect don't do drop test, all think that their is no problem for safety device, but once had an accident, repent at leisure. Why not do regular tests and tests? The use of units blindly thinks that not bad is good. Actually good or bad for safety device can only judge by test and inspection in the daily operation is not sure whether it is good or bad, for those who are serving for safety device, or advice for the earlier inspection and regular test, only accomplish know fairly well, to malignant accident prevention rather than cure.
Q:Can a construction elevator use a single cage
Seriously, a construction elevator in wuhan just happened, and 19 people died. Go and see!
