Oil purifier / filter
Product details:
The product has obtained national patent, patent number:
200610098137.0 and 200620125976.2 other two patents, and has passed
the technical appraisal Jinan Railway Bureau, in 2006 in Xuzhou
depot had been used.
Crane hook slide control device is a crane hoisting mechanism
mounted on the safety protection device, is the application of our
factory engineering and technical personnel of modern electronic
technology, developed patented new crane safety devices.
The device eliminates the slip hook condition to ensure the safety
of lifting heavy objects, lifting the Secretary to protect the
personnel, lifting the personal safety of installation; to avoid
the crane hook slide caused by the motor, transmission speed and
harm, reducing Driver fatigue strength of the work, just like a crane added a
"safety lock", with good economic and social benefits.
The control device is widely used in overhead cranes, portal
cranes, gantry cranes, tower cranes, loading bridges, mine hoist
and other lifting mechanism, simple, complex two models fully meet
the various tonnage, on various occasions needs.
>> The working process
Speed Series Resistance current electrical structure of the crane
because of its reasons, in heavy air, pull up and drop weight in
the process, there is the danger caused by the hook slide, and thus
must be installed on the crane an emergency stop button for the
driver in the slip Hook appears, press the emergency stop button to brake. Crane control method such that there are two risk factors.
1, if the brake system as insufficient braking torque mechanical
reasons, or because the result in brake torque with less wear and
tear, or the brakes do not brake for electrical reasons, it will
form a slip hook.
2, if in the course of their work, the operation is not in place,
will form a slip hook, this time in case of driver response lag,
sneak a certain speed under heavy loads, even if the brake, it can
not effectively stop the heavy in the air, the formation of slip hook.
Crane hook slipped a direct consequence: the damage caused by heavy
crane for speeding leaving transmission, hoisting motor damage, the
Division will result in more serious personal injury hanging.
Conditions for the crane to analyze the reasons for the formation
of slip hooks, one for the artificial control variable automatic
control, automatic detection of crane operation. State of the driver from the hard work will be freed. Second, double brake method, increasing an electric brake, electric
brake + brake so that the insurance crane very safe.
The motor is running, anti-slip control system for hook identify
the direction and speed of the motor is running, the controller in
real-time analysis, automatically determines the motor is running
in the normal range or in a slide hook state. If analyzed in the normal state, no treatment; If the analysis is
to slide the hook out of state, immediate protection action. J Series control system to power brake crane control cabinet. E Series control system to power brake crane control cabinet, while
allowing 150% of the electricity generated by the motor braking
torque, even if the brake failure, but also in the air Diaozhu
lifting heavy objects, heavy objects to ensure that the hook will
not slip
