Product Description:

Elevator Three-Drive 650 Frequency Conversion


Elevator three-drive 650 frequency conversion (also known as external elevator, elevator for short) is widely applied to vertical lifting transportation of personnel and materials, is essential good transportation equipment in industrial or civil buildings, large bridges and vertical shafts, and can be applied in warehouses, high towers and other different occasions in a permanent or semi-permanent way. Compared with other lifting mechanisms, the product features stability, safety, reliability, no requirement on additional arrangement of machine room shaft ways, convenient assembly and disassembly, high carrying flexibility, etc., and particularly has obvious effects of relieving the labor intensity of constructors, accelerating project processes and improving working efficiency.
SC200/200 construction elevator is a high-performance product which is newly researched, designed and launched by our company. The elevator features reasonable design, novel structure, stable operation, complete and reliable safety devices and convenient installation and maintenance, and mainly has the following characteristics:

1. The transmission mechanism is driven by two motors, and pinions and racks are safe and stable due to uniform stress.
2. To ensure the safe operation of the elevator, an overload switch, a speed limit switch and other safety switches are arranged in the circuit; when overload, speed limit and other conditions occur in the operation process, the elevator automatically prevents accidents at once. Each door on cages is provided with a limit switch; when any door is opened abnormally, all the cages cannot start or immediately stop operating.
3. Each cage is provided with an anti-falling safety device which can extremely effectively prevent the cages from falling and ensure the safe and reliable operation of the elevator.
4. The electric control system of the elevator has a simple circuit, is convenient to control and maintain and is reliable. When operating normally, the elevator can be controlled to operate by a handle or button in a cage, can be stopped at any time at any position needing the stop, and can be controlled to stop automatically by upper and lower terminal limit switches at upper and lower terminal stations. When the upper and lower terminal limit switches fail to act, limit switches additionally arranged on the elevator can cut off the power supply in time to stop it in a braking mode.
5. The steel structure adopts a computer-aided design mode and is scientifically and strictly calculated to meet the requirements of reasonable structure, reliable intensity and light weight.
6. The elevator can be self-mounted or make standard knots detached by using a hanger rod on a cage. All the other parts can be conveniently mounted and dismounted, and components are easy to replace.
Attached: construction elevator model compilation method
The model of the elevator consists of class, group, type, feature, main parameter and deformation codes.
Notes: The main parameter code includes rated loading capacity codes of two cages, for example, only one main parameter code is marked on a single cage.


Example 1: SCD120
Representing a pinion-and-rack construction elevator with a single cage, the rated loading capacity of 1,200Kg and counterweight.

Example 2: SC200/200
Representing a pinion-and-rack construction elevator with double cages (each cage has the rated loading capacity of 2,000Kg) and no counterweight.

Q:How to set up the construction elevator?
Direct contact with the elevator company, and they give you a plan for the construction of a pre-buried piece, and the parameters of each elevator are different,
Q:Can construction elevators be taken by people or by goods
The construction elevator can be taken either by person or by cargo Material hoist (dragon door frame, well frame) can be carried only, not by person
Q:How many kw is the sc construction elevator
The construction elevator sc200/200 is rated at 63 kw power, and the power consumption is greater.
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:The construction of more than many floors must be used for construction elevators
Elevator drivers must be trained in special safety technology, qualified for examination, and will be on duty. Strict drunken work. The driver must be familiar with the performance, construction, maintenance and maintenance of the elevator, and fill in the mechanical resume and the required reports in time. No inflammable, flammable goods and other sundries shall be piled up in the vicinity of 5m in the construction elevator, and no ditch, pits, or groove shall be dug in this area. The floor feed of the elevator should be set up for protection. When the cage is repaired, if the parts are removed and the weight of the ladder is below the weight, the ladder cage must be locked in the rail. It is strictly forbidden to use the shaft of the construction elevator to support the cable line and other items not related to the elevator. A tower crane or other lifting machine that is built on the same site shall be more than 5m above the elevator and should be properly protected against collision. After the construction elevator is installed, it must be checked and approved by the relevant personnel.
Q:Construction elevator positioning should consider which problems
It is convenient to install the wall with the wall
Q:Do the elevator need to be installed when the main project is in construction
The top brass usually need to install the construction elevator.
Q:Is the elevator detail a construction plan? Do you have a detailed picture of the elevator?
The construction diagram of the elevator appears to be a qualified elevator construction unit
Q:How does the construction elevator add up
You can use a ready-made high-altitude operating platform and a high-altitude working platform
Q:The staff on the construction platform shall not exceed the number of people
Different models have different load rating and platform lift platform size, this depends, suzhou new aluminium alloy elevator, Lin professional aluminum alloy lift platform.
