The advantages of bolted cabin

The body of the bolt or the threadless part always acts like a rod or shaft and resists the forces that would cause the bolt to shear, and on the other hand, it prevents the bolt from moving and shearing off. It’s interesting to know that room bolts, due to their design structure, alleviate many of our concerns.

For instance, one advantage of room bolts is the fit of the installation hole and the presence of a protrusion on the structure of the bolt itself, which prevents the possibility of slipping and movement between plates.

Generally, bolted connections, due to their design structure, do not fail in areas subject to sudden loads and impacts.

If bolted connections fail at one point of the joint, unlike welded joints, they don’t present a problem! This is because other parts of the connection still can bear the load.

Usually, at high temperatures and in the event of fires, bolted connections have more resistance to heat due to the properties of their alloys.

During the welding process, due to high temperatures, the metal plate may warp and distort, eventually causing the entire cabin to twist! However, with bolted connections, this effect is about zero.

The threads on the bolts, due to the structure they possess, inherently have a locking property, and combining them with plain and spring washers increases the resistance against loosening.

Bolted connections are not permanent and are very useful for repair and maintenance, simple inspection, and parts replacement.

What is an Elevator Cabin Panel?

An elevator cabin panel is an electronic control panel installed inside the cabin. This panel features various buttons including floor selection, door open/close, and emergency services such as alarm and elevator suspension. It registers passengers’ commands according to their needs and transmits them to the control panel. The control panel processes the data received through its sensors and operates promptly.

The placement of the Car Operating Panel

The new Harmony collection is designed so that it specifies the placement of the operating panel within the cabin and can aesthetically be part of the cabin’s overall design. We suggest that if you like the Harmony collection, also buy the operating panel from General Cabin and don’t change its designated placement, as this may diminish the beauty of the cabin.

Should you ignore these considerations for any reason, we recommend a hinge handle.

Hinged Cabin Operating Panel

The hinged cabin operating panel is one of the new products of General Cabin Company, which significantly aids in improving the performance of elevator maintenance and service companies.

Imagine one of the flush-mounted push-button panels inside your elevator cabin breaks down and you need to replace or repair it. This concern makes the repair of a small button difficult and time-consuming. The hinged panel is installed at the cabin’s front panel by default, ensuring that not even a centimeter of the cabin’s useful space is compromised. This measure can assist elevator service and maintenance companies in conducting the servicing and maintenance processes easily and safely. Nevertheless, the hinged operating panel has its shortcomings; even if special buttons or monitors are used, it may not make the operating panel sufficiently distinctive and appealing.

Elevator photocell

The elevator photocell is an electronic component used to ensure elevators’ safety. A photocell is a collection of light sensors installed at the elevator’s entrance doors, whose function is to control the space between the doors to ensure no obstacle in the path when the doors are closing.

This system typically includes one or more infrared lights transmitted from one side of the elevator door to the other and a series of receivers that catch this light. Suppose a person or an object is situated between the two doors and prevents the infrared light from reaching the receiver. In that case, a signal is sent to the elevator controller, causing the door-closing operation to stop, and the doors remain open until the obstacle is removed.

Photocells play an important role in elevator safety and prevent accidents that may occur due to people or objects getting trapped between the doors. Modern safety standards have made the use of photocells almost compulsory in every elevator installation.

The floor of freight and vehicle elevators

The floor of freight and vehicle elevators is designed to exhibit high durability and strength, ensuring resilience against heavy loads and pressures. Therefore, the popular and practical selection in the industry for outfitting freight elevators is the use of chequered, or tread plates. The unique pattern of raised treads on these plates significantly increases friction, which not only prevents the slipping and sliding of objects within the cabin but also enhances security and stability during transport.

 

The anti-slip property provided by these treads plays a fundamental role in increasing the safety and efficiency of transportation within these cabins. Furthermore, the overall strength and durability of the plate are substantially improved thanks to the protruded pattern, which can cover many structural challenges, potentially offering up to three times the pressure tolerance compared to plain, treadless sheets.

What is a Guide shoe?

One of the main parts of the elevator cabin is the shoe, which has a good effect on the smooth movement of the elevator cabin and the counterweight of the elevator.

The shoes are installed at the bottom and top of the counterweight and the cabin, and their main task is to guide the counterweight and the cabin along the elevator guide rail. Shoes are produced in different types and materials, prices, and qualities.

What is the use of elevator shoes?

Contrary to its small appearance, this elevator component has many applications. Guide shoes are used in all elevators, including hydraulic, traction, and magnetic ones. As mentioned, the main role of guide shoes is to assist in the smooth movement and reduce the slippage of the elevator cabin and the counterweight along the elevator guide rails. All this contributes to the improved movement of the elevator.

Elevator guide shoe Types

In general, 3 types of guide shoes are used in elevators:

Roller guide shoes: These guide shoes are placed as three rollers on the machined faces of the rail. The collection of these three rollers and their base comprises the roller guide shoe, which is not sliding. Each roller in these guide shoes has a spring that prevents the transmission of a significant amount of shocks from irregularities by absorbing them, to the cabin. The quality of the bearing material and the polyurethane used impacts the effectiveness of the roller guide shoes.

Sliding guide shoes: The most common type of shoe blocks are the sliding guide shoes, which consist of different pads including rubber, polyurethane, and Teflon. Because sliding guide shoes are in full contact with the rail and have no slack, they transfer almost all imperfections and vibrations from the rail connection points to the elevator cabin. However, some shoe blocks, like Hitachi guide shoes, absorb many of these shocks from irregularities. The maximum usable speed for these shoe blocks is 2.5 meters per second.

Fixed Guide Shoes

Features of General Cabin Guide Shoes

Vibrations and shakes always occur when the elevator cabin passes over the rail joints. The guide shoe neutralizes these vibrations and ensures the uniformity and smoothness of the elevator’s counterweight and cabin movement.

Unlike other guide shoes on the market that use a spring for damping, General Cabin’s design guide shoes benefit from a plastic intermediary.

One of the advantages of using rubber is the ability to react quickly and effectively to applied forces and reduce the vibrations of the cabin assembly and its accessories.

The method of attaching and installing this rubber to the body of the guide shoe is such that it allows the moving part of the guide shoe the possibility and ability to move in various directions: vertical, horizontal, and angular.

The use of bent sheet metal in the body of the guide shoe increases the sheet’s strength and provides suitable resistance against applied forces.

The reinforcement placed behind the guide shoe body increases the structure’s resistance to bending forces. Teflon, a material known for its anti-wear properties, is used for the part in contact with the rail in the Hitachi design guide shoe.

A vertical groove in the rail holder ensures that a certain amount of lubricant is always kept in place, leading to reduced friction between the guide shoe and the rail and, consequently, smoother movement.

A unique design feature is the inclusion of a curved section at the top and bottom of the guide shoe, which allows for gradual contact with the rail. This results in smoothness at the initial start and prevents vibration.

General Cabin’s design guide shoe is capable of being used at speeds of up to 2 meters per second with provisions made for such operation. This guide shoe can withstand pressure with a nominal load of more than 1 kilonewton and has the same capacity to endure lateral forces.

The design of the mounting holes for easy adjustment and installation and the provision for an oil reservoir are other advantages of this type of guide shoe.

Unlike conventional guide shoes that are fastened with four screws, this guide shoe has a large contact surface with the rail, which is significant. This increases the robustness of the guide shoe in heavy-duty applications and larger cabins.
