General specifications

Door Finish: Visible details for the users.

GOLD Elevators: The Montanari machines make the transfer of energy and the concept of movement more efficient, since their engineering does not have gears that generate noise and high maintenance costs due to the change of worn parts.

Capacity: It refers to the number of people or weight in total kg that the equipment can move.

Collective in Descent: Calls are handled in the following way: On the way up, the elevator attends to orders made from the car keypad in order of proximity. When it finalizes the orders for the users inside the cabin, it fulfills the orders for the floor. On the way down, the elevator attends to the registrations made from the car keypad in order of proximity, and also stops at the floors that have made a call. The purpose of this maneuver is to be installed in residential buildings, where the highest percentage of calls made from the floors are to go down to the main floor.

With machine room: The machine room is the space that contains the elevator machinery. It is a very important element since it depends on the structure of the building where the elevator will be installed. The elevator with a machine room is more accessible when it comes to maintenance and adjustments of the equipment, as well as salvage, and in many cases without having to stop the elevator. Therefore, the maintenance cost is more accessible since possible changes and breakdowns are solved in less time.

Group control: This program manages the operation of more than two elevators. The maneuver itself establishes a permanent communication between all the elevators in such a way that it assigns each external order to the car that is in a position to serve it in the shortest possible time.

Duplex:  Manages the movement of two elevators. The maneuver itself establishes a permanent communication between the two elevators in such a way that it assigns each external order to the car that is in a position to serve it in the shortest time. The criteria that you follow for the car allocation are: proximity between the external call and the car, the car's direction of travel and the car's load level (empty, partially occupied or full). There is a single control per floor with two buttons (up / down).

Operation: How the equipment operates, generally there are four types that are; Downhill Collective, Simplex, Duplex and Group Control.

PIT: Closed vertical space where one or more elevator cars are housed, including the pit. Also called an elevator shaft.

Travel distance:  The total distance that the elevator travels. 

Simplex: It is the simplest maneuver in terms of structure and operation. The first person (or group) to press in the car or on the floor, with the elevator stopped and unoccupied, is used in elevators for low-traffic residential buildings, who has complete control of the elevator. This control remains until the elevator completes the order (transfer to the corresponding floor and door opening).

Machine roomless (MRL): Make better use of space and save on construction works. MRL (machine room less) machines are environmentally sustainable, as their engineering is based on a 2: 1 system which allows the loads on the machine to be reduced by 30% compared to a 1: 1 system.

Door System

This is the set of components that interact with each other to automatically operate the opening of these.

Over-travel: Space between the last elevator stop and the top plate of the shaft.

Doors type: It refers to the type of opening of the elevator car doors.

Internal Cabin

Mirror:   Located at the rear of the cabin.

Ceiling:  Stainless steel ceiling finish, which includes internal cabin lighting.

Front cabin elevator: Front cabin finish in stainless steel.

Pared posterior: Rear cabin finish, it is usually installed with a half mirror and the lower part in Formica or Stainless Steel.

Side walls: Cabin side finishes, usually installed in Formica or Stainless Steel. 

Handrail: Stainless steel holding rail for hands in the cabin.

Floor:  Cabin floor finish.


NTC 5926-1 certification:  This normativity establishes the requirements that guarantee the legitimate objectives of protection against risks of electrical origin, for the essential precepts have been compiled that define the scope of application and the basic characteristics of electrical installations and some requirements that may affect the relationships between the people who interact with electrical installations or the service and users of electricity.

Control: Electronic system To handle the movement of the elevator, within its components is the speed and PLC variator.

Manufacturing:  National assembly of elements, with certification and RETIE certification.

Electromagnetic Brake: Braking operation in conjunction with the machine coil.

Floor Selector:  Electronic system in the control, which controls the type of operation of the equipment.

Leveling System: Electronic system, controlled by the control in conjunction with the equipment speed controller. 

The speed with control v.v.v.f.: Speed controller for induction or synchronous motor elevators with or without gears.

Speed with control v.v.v.f.

Tractor system

Traction pulley and deflector: Traction mechanism located on the machine. The Deflector Pulley is/are the deflection mechanism used to transfer movement to the cab.

Machine type: Traction solutions for the elevator. SILVER elevators with gear machines, GOLD elevators with gearless machines.

Traction without gearless gears:  Synchronous machines (Gearless) which unlike asynchronous engines add permanent magnets in the rotor, allowing the rotor to move at the same speed as the stator.

Gear Traction: The machines with gears (GEAR) and reduction motor, generally have induction motors, where the torque is generated by the application of an alternating current (AC) to a geometrically distributed three-phase wiring, whose name is stator.

Disclaimer: Electromechanical machine with asynchronous and synchronous motors, the movement transfer can be with gears (crown and worm) or without them.

Measurement units

Capacity (Kg):  Unit of mass measurement. 

Power (Kw o Hp):  Power measurement unit.

Speed (m/s):  Unit of measure for speed and velocity.

Voltage (V): Voltage is the magnitude that accounts for the difference in electric potential between two determined points.

Cab buttons:  Elevator call or operation element in the car.

Hall buttons: Elevator call or operation element at each stop. 

Wiring : 
Building connection, from which wires the installation of the elevator electrical system.

Position Indicators: Light signal that shows the location of the elevator.

Payment Methods

Electronic elements in the car and elevator operating commands.

Pay program:  It is the payment schedule and the percentages that allow you to buy any Elevator solution, hire services or cancel all kinds of debts.

Term:  Time for the execution of all the works.

First Installation Phase:  The supply and arrival of guides, headboards or suspensions and floor frames.

Second Installation Phase: The supply of the machine, control, cabin and landing doors.

Set up: The wiring, tests and final adjustments that are made to the elevator before it is delivered.
