LIMIT SWITCH SENSOR

The A2B limit switch sensor is a switch for locking the hook ascent. A fundamental part of the load and safety limitation systems, it can be adapted and installed on any type of machine: from the largest and most complex lattice cranes to the simplest and small hydraulic cranes, without specific tools or prescriptions.
It has been designed to comply with the recent Machinery Directive, and is available, optionally, equipped with a chain and weight of approximately 5Kg (WE-5KG).
The limit switch sensor adopts a very simple and reliable spring mechanism, incorporating a microswitch according to CE standards with normally closed contacts, with a high degree of MTTF, as prescribed by the European regulations.
It is able to distinguish between the limit switch alarm and the alarm due to disconnection of the electrical contact or short circuits, informing the operator and activating the possible automatic safety lock.
