Home elevators hoists ? What is the difference between a material hoist and a construction elevator

Whether it is a home elevator or a commercial public elevator, the biggest concern is safety, and the difference between the two is mainly reflected in the load, lifting speed and height. The lifting speed of the home elevator is generally in the stable operation; The load shall not exceed 400kg, and the lifting height shall not exceed 15m. When purchasing a villa home elevator, it is necessary to look at safety, stability, after-sales and operation comfort.

The stability of elevator use, less failure rate, and after-sales service are also very important, and try to choose a brand with reliable quality and worry-free after-sales. Whether the experience of taking the elevator is comfortable and whether the operation is convenient are also factors that need to be considered.

Construction hoist: Construction elevator is often referred to as construction hoist, but construction hoist includes a broader definition, and the construction platform also belongs to the construction hoist series. The simple construction elevator is composed of several parts, such as the car, the drive mechanism, the standard section, the attached wall, the chassis, the fence, the electrical system, etc., and is the manned and cargo construction machinery often used in the building, because of its unique box structure to make it comfortable and safe to ride, the construction elevator is usually used with the tower crane on the construction site, the general load capacity is 1-3 tons, and the running speed is 1-60m min.

Material hoist: The material hoist is equipped with safety protection devices such as broken rope protection safety device, docking safety device, buffer device, upper and lower height and limit limiter, and anti-loose rope device.

Similarities: all belong to lifts, and all follow the same implementation standard specifications: GB T10054 2005 construction hoist, GB10055 2007 "Construction hoist safety regulations".

Differences: The electrical control system is different. The construction hoist can be controlled in the box and the ground, which belongs to the control at both ends, and the material hoist belongs to the portable control end.

1. The transmission mode is different.

The construction elevator generally adopts the transmission mode of motor and gear. The material hoist conveying mode is mainly the configuration of the main engine and wire rope.

2. Different uses.

Construction elevators are widely used in building construction such as industrial and civil buildings, bridge construction, underground construction, large chimney construction and shipbuilding industry, suitable for vertical transportation of materials and personnel, as permanent or semi-permanent elevators can also be used in different places such as warehouses and towers.

Material hoist is a kind of mechanical conveying equipment with fixed devices, which is mainly suitable for continuous vertical lifting of powdery, granular and small materials, and can be widely used in the lifting of bulk materials in feed mills, flour mills, rice mills, oil mills, starch mills, grain depots, port terminals, etc.

3. The scope of application is different.

Construction elevators can generally ensure the safety of personnel and material transportation, and need to be started by special personnel. The material hoist can only carry out some simple material transportation, and the speed is relatively slow.

Similarities: both are construction vehicles.

Differences: The material hoist is mainly used to transport materials, usually can not be used as personnel transportation, its appearance is generally relatively simple, there is no corresponding protective device for transporting personnel, and the transmission mode is mainly the configuration of the host and wire rope. The shape of the construction elevator is relatively perfect, with a complete frame and safety protection devices, to ensure the safety of personnel and material transportation, and a special person is required to start, and the transmission mode of motor and gear is generally adopted.

Function: The hoist is a kind of construction machinery, it can transport materials, suitable for residential buildings, freight yards, warehouses, shopping malls, restaurants, individual workshops, small factories and mines, can move, lift, load and unload materials, is a small lifting tool.

Function: Billion coal hoist is suitable for conveying powdery, granular and small pieces of non-abrasive and abrasive materials, with the main function of electric hoist and winch, specifications 300-600kg 500-1000kg, rope length: single crane 30 meters, double crane 15 meters, wire rope length can be lengthened according to user needs.

According to the working principle of hoisting wire rope, it is divided into winding mine hoist and friction mine hoist. There are two kinds of winding mine hoists: single drum and double drum, and the winding method of the wire rope on the drum is similar to that of general winch. Most of the monotubes have only one wire rope that connects to a container.

Each drum of the twin drum is equipped with a wire rope to connect two containers, one container rises and the other goes down during operation. Spiral wound mine hoists are mostly used in mines with an annual output of less than 1.2 million tons and a depth of less than 400 meters. The hoist rope of the friction mine hoist is hung on the friction wheel, and the friction with the friction wheel liner is used to make the container rise.

A container is connected to each end of the lifting rope, or one end is connected to the container and the other end is connected to the counterweight. According to the layout method, the friction mine hoist is divided into two types: tower friction mine hoist (the machine room is located on the tower at the top of the shaft) and floor friction mine hoist (the machine room is directly located on the ground).

1. Judge that there is a problem with the drive, and the drive is broken; 2, exclusion does not mean regret the problem of the driver, not connected to the motor is the green light, is the motor problem 3, the connection problem 4, the drive current is not suitable 5, the load is too large, how to solve the engraving machine driver light red light: 1, it is recommended that the customer check or replace the driver 2, rule out the problem that is not the driver, do not connect the motor is the green light, is the problem of the motor, replace the motor 3, remove the motor line on the drive, and then disconnect the line on the motor side, measure with a multimeter, the normal should be A+And A- is the pathway, B+ and B- are the pathways. Group A line and group B line should not be connected, but a measurement found that a group of lines and group B line are connected, that is, 3 of the 4 lines are connected, so it is judged that it is a connection problem, replace only take the wire, 4, check whether there is a problem with the mechanical part that has an axial direction, clean the lead screw and smooth bar, if there is still a problem, you can change the driver with the driver of other shafts, and the driver will change the drive if there is a red light on other shafts, If other drives have a red light on this axis, it is necessary to find a problem with the mechanical part.

The main differences are that the properties are different, the characteristics are different, and the applicability is different, as follows:

First, the nature is different.

1. The material is lifted back to the machine.

Material hoist is a kind of mechanical conveying equipment with fixed devices, which is mainly suitable for continuous vertical lifting of powdery, granular and small pieces of materials.

2. Construction hoist.

The construction elevator, also known as the construction elevator for the building, can also become an outdoor elevator and a lifting cage for the construction site. It is a manned and cargo construction machinery often used in construction.

Second, the characteristics are different.

1. Material hoist.

This kind of hoist has few requirements for the type and characteristics of materials, which can not only improve general powdery and small granular materials, but also improve materials with greater abrasiveness, good sealing and less environmental pollution.

2. Construction hoist.

Convenient and multi-purpose, on the basis of the traditional construction hoist, a steel bar conveying device and a concrete conveying device are installed, which can transport steel bars, concrete and construction personnel, and greatly improve the construction efficiency.

Third, the applicability is different.

1. Material hoist.

It is widely used in the lifting of bulk materials in feed mills, flour mills, rice mills, oil mills, starch mills, grain depots, port terminals, etc.

2. Construction hoist.

It is mainly used for the interior and exterior decoration of high-rise buildings, the construction of bridges, chimneys and other buildings. Due to its unique box structure, the construction crew is comfortable and safe to ride. Construction hoists are usually used in conjunction with tower cranes on construction sites.

DU PatenterAnswers for you:

The material lifting machine is a kind of mechanical return conveying equipment of fixed devices, which is mainly suitable for the continuous vertical lifting of powdery, granular and small pieces of materials, and is equipped with safety protection devices such as broken rope protection safety devices, docking safety devices, buffer devices, upper and lower height and limit limiters, and anti-loose rope devices.

Construction elevators are often referred to as construction hoists, but construction hoists include a broader definition, and construction platforms also belong to the construction hoist series. The simple construction elevator is composed of several parts such as the car, the driving mechanism, the standard section, the attached wall, the chassis, the fence, the electrical system, etc., and is the manned and cargo construction machinery often used in the building, because of its unique box structure to make it comfortable and safe to ride, the construction elevator is usually used with the tower crane on the construction site, the general load capacity is in tons, and the running speed is 1-96m min. The construction hoist produced in China is becoming more and more mature and gradually going international.

Generally, the material hoist is strictly forbidden to go to the master. The construction hoist has the kind of Venerable Master.

The material hoist only carries materials and does not carry people.

Construction hoists generally refer to dual-purpose elevators.

The difference lies in the rise and fall of the incoming material ratio.

The lifting speed of the source machine is slower, the safety coefficient is poor, and the lifting DU is smaller.

The height of the lift is shorter than that of the lift.

In fact, the most important thing is that the safety factor of the material hoist is much worse than the construction hoist, and the construction hoist will not shake when it rises to 150 meters. In a word, the material hoist is dangerous, and the hoist is safe.

Construction hoist: Construction elevator is often referred to as construction hoist.

machine, but the definition of construction hoist is broader, and the construction platform also belongs to the construction lifting and lowering machine series. The simple construction elevator is composed of several parts, such as the car, the drive mechanism, the standard section, the attached wall, the chassis, the fence, the electrical system, etc., and is a manned and cargo-carrying construction machinery often used in the building, because of its unique box structure, which makes it comfortable and safe to ride

The material hoist, as the name suggests, is used to load objects, cannot carry people, and has a height limit.

The external elevator is similar to the form of an indoor elevator, which can carry people and goods, and the height is not limited, as long as the buttress is added, it can increase with the increase of floors.

The material hoist mostly uses the chain type, and the external elevator is mostly the wire rope of the winch.

This is not always, there is no height limit, you can't always think about how high you are, and you should consider the height before installation, so as to manage the foundation.

This should consider the use and cost, the cost of the construction elevator is higher than that of the hoist, but the safety performance of the elevator is better, the hoist can only transport materials, can not carry people, or ask the leader, for reference only.

Elevators and hoists are inseparable from wire ropes, commonly used wire rope varieties are phosphate-coated wire rope, galvanized wire rope, stainless steel wire rope or plastic-coated wire rope, used in atmospheric environment, patented technology production of manganese phosphate coated wire rope has the longest service life, heavy corrosion environment preferred hot-dip galvanized - phosphated double-coated wire rope.

The phosphate coated wire rope produced by the patented technology gives priority to the use of manganese or zinc-manganese phosphating, compared with the smooth wire rope production process, only the final wear-resistant phosphating treatment process is added, and the wear resistance and corrosion resistance of the rope wire are greatly improved. At present, the fatigue test data shows that the fatigue life of the phosphate coated wire rope is about 3 times that of the smooth wire rope of the same structure (under comparable conditions in the laboratory), and there is a possibility of significant improvement with the study of the wear-resistant phosphate formula. Manganese phosphating is wear-resistant phosphating, which can solve the problem of wear and tear in the use of wire rope, and smooth wire rope is being eliminated, because phosphating coated wire rope is in short supply, which is currently more sought-after and for reference only.
