The personnel who have passed the training, qualified for the examination and obtained the certificate of the post shall be operated and repaired. (2) the capacity of the concrete base culture cooperation should not be less than 150kPa, the tolerance of 10mm and the drainage facility should be allowed. The distance between the guide bracket of the elevator and the wall of the building should be suitable, and the smoothness should be stable. (3) the lifter is used to control two directions, and the vertical control is 0.05%. Each floor shall have a platform, a passage, a fence and a protective door. No obstacles can be found. (4) the elevator that is installed in a dark place, and the passage shall be illuminated and a floor display lamp and floor number; A closed barrier should be set up in the well. The elevator shall be subject to acceptance by the technical director and the relevant departments, and shall be tested by the crash and shall be used in the rear. (5) in the use of or during the use of the elevators, the manufacturer or designated unit shall conduct the debugging and maintenance and verification. The lifter should undergo a fall test every three months and the fall test should be adjusted when the fall test exceeds 1.2 m. Every time it falls, the receiver should be repaired once.
Q:Where is the location of the elevator in the project
The position of construction elevator is usually set in the project to facilitate access to material, material handling and personnel up and down, not affecting the construction process.
Q:Excuse me: what is the meaning of heavy weight in the construction elevator?
This is very nice! Learn more! Thank you for your dedication...
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:How to save the elevator accident
Take escalator safety knowledge Passenger escalator before to keep checking your shoes clothing habits should fasten shoelaces wear skirt drag clothing such as optimum rolled up against the edge of the elevator, comb plate drag or stuck passengers carry baggage increase the risk of escalator accident now need extra or simply choose to take the stairs Escalator self-help hair accident? Every escalator, the stop button and denier hair escalator accident near the button passenger safety awareness should be kept between the first button escalator automatic stop energy efficiency to reduce accident damage Take escalator Cheng Shen fall should use to protect themselves as to avoid the rot slip or fall high neck should hands fingers crossed by strongly impact the dangerous clasped, protect brain neck elbows forward cover bilateral temporal pour knees bending forward as far as possible to protect the chest abdominal viscera side found important discoveries escalator before the sudden fall should the horse stopped footstep simultaneous for help inform passengers will forward near the accident should maintain a stable mood calm reason for avoiding the accident hair running blind hair stampede damage
Q:How many guides are in the construction elevator
The guideway hydraulic platform is a non-shearing hydraulic platform, which is suitable for the transport of goods between low floors. The product hydraulic system sets the emergency anti-falling, the upper and lower door interaction chain each floor and the elevating platform work mesa both can set the operation button, achieves multi-point control. The hydraulic electric appliances have optional safety configuration: emergency stop, overload alarm, deceleration adjustment block, leakage proof overload protection, etc. The product structure is strong, the load is large, the elevation is stable, the installation maintenance is convenient, is the economical and practical low floor space to replace the elevator's ideal cargo transport equipment. According to the installation environment and usage requirements of the platform, the different configuration can be selected for better use. Features: minimum height of 150-300mm, suitable for unexcavated pit, at the top without lifting, is the preferred lifting device for transporting goods between lower floors.
Q:What about the energy efficiency of the escalator
Variable frequency construction elevator energy saving effect general. Frequency conversion is not energy efficient. The difference between the frequency and the common machine is the smoothness and speed of the operation. Frequency conversion speeds up to 90m / 1 minutes and the average is only 35m / 1 min Frequency conversion when parking is slow down and stop Ordinary is directly stop delay parking and adjustment made door light who bow Angle decyl with brush spring connection will be better. The frequency conversion requires the site voltage to be strictly a little bit looser than the voltage requirement Energy consumption is: according to the elevator drive mechanism for general three transmission two kinds of the elevator are three 11 kw motor, that their energy consumption are 3 x 11 = 33 kw is hours each hanging basket consumes electricity 33 degrees, the actual power consumption will be bigger.
Q:Is the construction elevator the same as the construction elevator
Construction lifter is a kind of vertical lifting equipment standard name, generally refers to the SC model of the single or double hoisting cage hoisting cage, driven by gear and rack, (in recent years, there are many strands of wire rope drive), equipped with "" for safety device, can people goods with multiplication. The construction elevator is called a popular term, and the common site is called a rack elevator and a human cargo elevator, which means the same thing. Because this kind of product applies only to the construction site, it is very different from the common guest elevator. There are two other types of products that are common to this type of product, such as the SS single-column double cage (wire rope drive), which is called the material lift machine, which cannot be multiplied by people. There is also the WJ series double column single-cage (wire rope drive), which is called the dragon door frame, which is also not allowed to be passenger. Strictly speaking, the latter two kinds can't be called construction elevator, can be called so-and-so elevator. Above is a person's humble opinion, if be in and out, still hope the expert is correct!
Q:What is the meaning of double straps in the construction elevator?
One component of the elevator's drag system is the weight of the car. The other side of the car is connected to the top of the car by dragging a wire rope. It can be used for the energy saving of the elevator towing system, because the elevator load optimization is calculated by the theory calculation. The elevator should be calculated before the weight is weighed: the calculation principle is that the weight is equal to the weight of the car and half the load.
