What is the point construction elevator safety supervision mechanism
Construction elevator analysis many fall accidents, the main reason is caused by overload, form a overload is so due to the weight more than the weight of regulation: the second is due to the heavy radius of horizontal distance over the homework. After install torque limiter, when weight overweight or job radius is too large, and the technical performance of a moment than the construction elevator, automatically cut off the lifting or transformer power supply, and send out alarm signals, to prevent the accident.
Construction elevator for torque limiter has two kinds: one kind is electrical, the other is a mechanical type. Electrical on the display can be read at the same time to the moment, homework radius and the weight data, when close to the construction elevator allowed torque, early warning signal, easy to use, but influenced by operation conditions, poor reliability, easy to damage, maintenance inconvenience; Mechanical model no display device also no early warning signal, but reliable work, is to adapt to the site construction conditions, simple structure, lower damage rate.
Construction elevator venue reassemble, transform ratio during the transition and change lift arm length, must adjust the torque limiter, electrical overload alarm point must also try to actual operation radius and the actual weight to calibrate. The elevator to the construction of car horns, choose type mechanical torque limiter, must adapt to and the construction elevator, (should choose the same kind of plant type).
