SH6050-16 8/2-1 L4
aux. SH5025-20 4/1 L3

For the maintenance of the sugar mills during the harvest season at a sugar mill, we needed to modernize old equipment. The SH60 with a 20-ton capacity turned out to be the ideal equipment for the maneuvers. Its compact design allowed for the inclusion of an auxiliary hoist, the SH50 with a 10-ton capacity. 

Design

• Two hoists, main SH60 and auxiliary SH50, mounted on a square profile frame assembled on a double-girder trolley.

• Special gauge 

Hoists for individual use, namely "A or B"

IP55 Protection

Electromechanical ratchet brake on the drum

ZENTRATEC, polipastos para el manejo de materiales
Ratchet Brake

The project required a secondary brake to ensure that the rollers of the mills could be suspended indefinitely for access to the interior of the machinery. We included a ratchet brake mounted on the drum, which is ideal for the application.

The pawl mechanically engages, keeping the drum locked. It will only release the brake through an electromagnetic actuator.


Our Story

Our Story

Ayer construimos el México de hoy

Hoy preparamos el México de mañana

Planta VW de México, 1968

Con respeto y mucho cariño a los incansables forjadores del México de los sesentas, presentamos un testimonio fotográfico que consideramos ilustrativo para evidenciar los retos de las generaciones pasadas.  

Con grán esfuerzo y la frente en alto, hicieron posible nuestro México de hoy.

En 1963 los primeros pasos fueron dados para encaminar la fabricación de puentes grúa en México. Campos Hermanos, Técnicos Argostal, Hércules y algunos más se encontraban dominando el mercado.

Fueron tiempos austeros, sujetos al ingenio e improvisación. México estaba despertando hacia la industrialización. La productividad exigía modernidad, progreso y visionarios.

En ese entonces, nuestra primera generación de «grueros» estaba por nacer para apoyar las grandes necesidades del país. A lo largo del tiempo con el impulso del fundador, Wolfgang Honack, nacieron un sinnúmero de empresas relacionadas a la fabricación y mantenimiento de puentes grúa. 

 

Equipo Industrial

«EISA» 

La fabricación de la primer grúa en 1963 se formalizó en un predio baldío en Santa Clara, Ecatepec, Estado de México. Era el entusiasmo de un emprendedor, sus empleados y un grán país, el que daría una oportunidad única de servir. 

Los años por venir iban a ser una aventura con altibajos, siempre sorteables con la grán motivación del personal. 

  • 1963

     

  • 1967

  • CNIA 1975

     

A mediados de los setentas EISA se consolidó como uno de los fabricantes más importantes de puentes grúa en México. El contrato con CNIA, la Comisión Nacional de Ingenios Azucareros, con más de 50 puentes grúa y «arañas» destinados al manejo de zafra terminaron consolidando el grán esfuerzo de crecimiento. 

  • 1975

     

En 1975 se inauguró EISA en Atizapán de Zaragoza, Estado de México

La creciente demanda por puentes grúa de altas capacidades y dimensiones exigía una planta moderna con facilidades para producir puentes grúa en serie. Se incorpora un taller mecánico con máquinas herramienta  para fabricación de tambores, ruedas, engranes y testeras (cabezales).

Hoy en día el recuerdo de los esfuerzos del pasado motivan para redoblar esfuerzos. Las grandes empresas que nacieron el siglo pasado y movieron sus materiales con grúas «EISA» han pasado a ser empresas de renombre mundial. Hemos sido parte de un grán México y es un orgullo llamarnos «Familia». 

Estamos a sus órdenes,

HBC remote control

HBC

When the control is your best ally

Your trustworthy partner 

The use of radio controls in overhead cranes provides enhanced safety, comfort, and flexibility for the operator, which in turn improves efficiency and productivity in loading and unloading operations.

One of the primary advantages of using radio controls in overhead cranes is the enhancement of safety and convenience for the operator.

HBC remote controls enable the operator to be independent and move within the work range at their convenience, at any time. The wireless remote can be operated from a safe distance or a secure location, with an optimal view of the work situation and minimal exposure to noise, dust, or vibrations.

Safety should not compromise the efficient functioning of the radio system and the machine; secure technology must also be highly available. Concepts such as redundancy in terms of software and hardware, along with intelligent frequency management processes, allow us to enhance both safety and availability, even with a growing number of radio users.

HBC wireless remote controls are optimally equipped for extreme requirements. Protection at work and safety while operating efficiently are fundamental principles at the core of the product concept. The HBC remote control safety chain consists of highly qualified input elements located on the mobile radio transmitter (e.g., joysticks, linear levers, switches), the radio transmission itself, the output elements of the radio receiver installed on the machine (e.g., relays, digital outputs, serial interfaces, bus systems, etc.), and includes the qualification of the electronics and software (also in terms of their diagnostic capability).

ZENTRATEC, polipastos para el manejo de materiales

Micron Ex pendant control from HBC.
In addition to the standard buttons for hoist/crane movement, the pendant control may also feature other elements such as on/off buttons and switches, and indicator lights that display the status of the overhead crane.

Fostering a safe lifting workplace

ZENTRATEC, polipastos para el manejo de materiales

HBC Ex, there is no safer equipment!

The explosion-proof HBC push-button control is a device used in hazardous or potentially explosive environments, such as chemical plants, oil refineries, or mines. It is designed to prevent the generation of sparks or flames that could cause an explosion.

This type of pendant control station is constructed from materials and components that are resistant to ignition and fire. For instance, it may be made of stainless steel or corrosion-resistant aluminum and feature a sealed enclosure to prevent the ingress of flammable gases or dust.

Our HBC pendant controls come with specific certifications and standards that ensure their safety in hazardous environments. For instance, they can comply with the ATEX (Atmospheres Explosibles) regulations in Europe or the NEC (National Electrical Code) standards in the United States.

Hoist and Crane Controls

Controles de Mando para Polipastos

The use of radio controls in overhead cranes provides enhanced safety, comfort, and flexibility for the operator, which in turn improves efficiency and productivity in loading and unloading operations.

One of the primary advantages of using radio controls in overhead cranes is the enhancement of safety and convenience for the operator.

Firstly, the use of radio controls allows the operator to control the overhead crane remotely, which means they do not have to be close to the load or in an uncomfortable position to operate the equipment. This reduces the risk of injuries or accidents, as the operator can maintain a safe distance from the load and have a clear view of the operation.

Zentratec polipastos STAHL
HBC Radiomatic

Additionally, radio controls can be equipped with a range of integrated safety features, such as emergency stop buttons and speed control systems, that allow the operator to quickly halt the overhead crane in the event of any issues or hazards. This provides greater peace of mind and confidence to the operator, knowing that they can immediately stop the equipment if necessary.

Another advantage of using radio controls in overhead cranes is the flexibility and mobility they provide. Being untethered from cables or fixed controls, the operator can move freely around the work area, which enhances visibility and maneuverability of the overhead crane. This is particularly beneficial in confined spaces or in situations where precise and agile control of the equipment is required.

In addition to the standard buttons for hoist/crane movement, the pendant control can also include other elements such as on/off buttons and switches, and indicator lights that display the status of the overhead crane. -

STAHL SWH Ex, the best!

The STAHL SWHex explosion-proof pendant control station is a control device used in hazardous or potentially explosive environments, such as chemical plants, oil refineries, or mines. It is engineered to prevent the generation of sparks or flames that could trigger an explosion.

This type of pendant control station is constructed from materials and components that are resistant to ignition and fire. For instance, it may be made of stainless steel or corrosion-resistant aluminum and feature a sealed enclosure to prevent the ingress of flammable gases or dust.

The word ATEX comes from the French term "ATmospheres EXplosibles" and is an important directive in the field of protecting people and equipment in potentially explosive atmospheres. The National Electric Code defines Hazardous Locations according to 2 different standards; NEC 505 and NEC 500. NEC 505 defines the Zone System and NEC 500 defines the Division System.

 

  • Product Directive 2014/34/EU
  • Operational Directive 1999/92/EC

2014/34/EU, the EU has created the ATEX Directive. This explosion protection directive, derived from the French term "atmosphère explosible," has unified various pre-existing regulations.
