Q:6 layer of brick and concrete construction project, have tower crane still need construction elevator?

6 floors of brick and concrete construction projects, tower cranes do not need construction elevator. Brick structure refers to the building of the wall of vertical bearing structure, column, etc. By using brick or block masonry, lateral load-bearing beam, reinforced concrete structure is adopted for floor, roof boarding, etc. In other words, the masonry structure is a small amount of reinforced concrete and most brick wall bearing structures. The masonry structure is a kind of hybrid structure, which is composed of brick wall and reinforced concrete beams. Suitable for small width and depth, room area is small, multilayer or low-rise buildings, for load bearing walls can't change, while the frame structure of wall body can be altered.

Q:Why do you ask the construction elevator to be a certain distance from the structure? Is very close to if not you can not bother to do delivery channel security protection or something, out of the elevator out directly, and attachment should be able to get more easily, to solve. Thank you very much!!

Isn't there a car? Normally, the center line of the car should be in the same line as the support frame center. If the frame body (standard) get into the building, inevitably cause capsules center, usually the center of gravity and center is not a straight line on the standard section, capsules will force up and down roller, increase and the frame body wear, and certainly not safe.

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:Does the new approach builder need a localizer test report

According to the current national standard "construction lifter safety regulation GB10055-2007 the provisions of article 11.1.9: for safety device can only be valid for use within the period of validity of calibration, the effective calibration period shall not exceed one year. According to the current industry standard "progressive construction lifter gear cone drum for safety device, the regulation of JG 121-2000: for safety device, no matter use or not, after the expiration of the valid inspection must be back to check calibration. The life of the safety device is five years. In order to ensure the safe use of the construction elevator, the construction elevator should be carried out every three months - the fall test and the formation record. It is recommended to refer to jgj215-2010, the safety technology regulations for building construction elevators.

Q:The difference between the derrick and the construction elevator?

They're the same. HAULOTTE answer for you

Q:Whether the construction elevator is a dual-purpose elevator

The vertical transportation machinery in construction is mainly the material elevator and construction elevator. Material hoist can slide can't manned, suitable for multilayer use, construction elevator is used only for the top, both manned and can slide, in general the construction elevator for dual-use goods of choose and employ persons outside the elevator.

Q:How large a leakage protector is used for the construction elevator

The leakage current is less than 30 milliamps The short circuit current is typically 1.2 to 1.5 times the rated current If the motor is rated at 10, it is usually used with a 125-15 leakage protector

Q:The staff on the construction platform shall not exceed the number of people

Depending on the actual situation, different quality of platform specifications will affect the number of people manned. Hope can help you.

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:The construction elevator always jumps

The starting current is more than three times the running current, and your air switch is low in the maximum current
