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.

This series is high speed VF hoist, with a max. lifting speed of 96m/min, suitable for highrise building construction.


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:

Remark: 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, we can also manufacture cages of other size according to the user.

Q:Why is the construction elevator not so close to the structure?
The distance between the moving parts and the building and the fixed construction equipment shall not be less than 0.25 m. The main thing is to prevent the person from the point of view. For example, workers are on the third floor to look down, hanging cage, where is the result now hanging basket is go down from the fourth floor, if not the 25 cm, likely to brush "cut".
Q:What is the height of protecting door protection of construction elevator
Elevator protection door is strict according to the mandatory standard to set up elevator well protection measures for safety technology. The shaft must be set in the range of 1.5 to 1.8, with protective railings or fixed gate and protective railings or fixed doors. 2, elevator well in plus or minus zero layer need to set up the first safety net, every two layers, the upper part of most every 10 m AnQuanPing network design, network security quality must gb5725-1997 "safety net" of standard network, methods must be checked in accordance with the relevant provisions. Installation in the safety net elevator dismantlement, the operator should wear the seat belt according to the regulation. On the floor and roof, a short side hole is larger than 1.5 m, the hole should be set in the requirement of the protective railing, the bottom setting safety net. To set safety warning signs that meet national standards in the elevator shaft. Safety warning signs are clear, warning lights should be set at night. The protective railings and gates shall be marked with yellow and black stripes and shall be manufactured according to the standards of construction safety technical specifications. 5, elevator wellhead protection facilities need to dismantle or change temporarily, and by the project full-time safety sign shall be the responsibility of the project director, and ready to move or change the security countermeasures. To inform all staff at the same time; Recovery after safety facilities must be by the project director, full-time security personnel and other related personnel on-site inspection management, qualified rear can continue to use.
Q:Safety device for construction elevator
1. The governor To prevent the hanging basket construction elevator overspeed or fall and set up a safety device, is divided into a unidirectional and bidirectional type two kinds, the one-way speed limiter can only along the direction hoisting cage falling within the speed limit, two-way speed limiter can up and down along the hoisting cage speed effect on two directions. The speed limit shall be tested for performance in accordance with the prescribed time limit. 2. The buffer spring Buffer spring in spring seat connected to the base frame, so that when hanging cage fall accidents, reduce the impact of the hanging basket, at the same time ensure crane cage and weight drops landed into flexible contact, slow down the hoisting cage and the impact of weight landing. The buffer spring has a cone winding spring and a cylindrical spiral spring. Usually, there are two or three cone coiled springs or four cylindrical coils on the base of each cage.
Q:What is the main function of the construction elevator safety guard
When the cage is unexpectedly overspeed, the cage will be stationary on the rail frame and cut off the power supply to ensure the safety of personnel and equipment.
Q:The difference between the derrick and the construction elevator?
They're the same. HAULOTTE answer for you
Q:Should a fire extinguisher be equipped in the construction elevator?
A fire extinguisher will be required for the 500kg of manned cargo construction elevators at 500kg or more.
Q:How does the driver of the construction elevator do the search for a sudden power failure
There are clear rules for the safety of construction machinery (JGJ33-2001). 6.12.17 when the elevator is running in an existing abnormal condition, it should stop immediately and take effective measures to reduce the cage down to the ground level, and keep running after the failure. When the electric is out of control in operation, the stop button should be pressed immediately. The stop button is not allowed until the failure is ruled out. 6.12.20 when elevator in the operation of the midway stop due to power outages or other reasons, can be manually, the end of a motor brake electromagnet manual release slowly shake handshandle pull outward, slowly slide down the ladder cage, ladder cage fall shall not exceed the rated speed, manually drop must be conducted by professional maintenance personnel manipulation.
Q:How many floors do you need to install a construction elevator?
Do not have a regulation, as long as the benefit construction organization, installation does not install construction lift machine all can. It should be explained that the construction elevator has manned and pure cargo.
Q:Construction elevator positioning should consider which problems
It is convenient to install the wall with the wall
Q:The construction elevator should have those procedures
Construction elevator installation unit must have issued by the construction administration department of lifting equipment installation project specialized contracting qualification and construction enterprise safety production license, and within the scope of the qualification licensing business engaged in the installation of construction lifter removed.
