Product Introduction of the mechanical two rope clamshell grabs
The mechanical two rope clamshell grabs is suitable for all kinds of cranes with double lifting device structure, and is mostly used in ports, docks, construction roads and bridges and other industries.
According to the material characteristics, it can be equipped with light, medium, heavy, and super heavy. Suitable for grabbing all kinds of loose accumulations.
Then various cranes. Equipped with two sets of motor reels (i.e. electric hoists), each set of reels leads to a wire rope, one of which serves as the support on the grab balance frame, and the other wire rope passes through the pulleys of the upper and lower beams to form a pulley block, which plays a role in the opening.
Mechanical two rope clamshell grabs are an effective tool for loading and unloading bulk cargo such as yellow sand, coal, ore powder, and bulk fertilizer in various harsh environments.
Mechanical two rope clamshell grabs has a simple structure, a novel opening and closing mechanism, easy to operate, and can accurately complete the opening and closing actions in various states.
Mechanical two rope clamshell grabs adopts a three-dimensional virtual design, and ANSYS software is used for strength analysis and verification. The weight distribution is more reasonable and the service life is longer.
The upper bearing beam of the mechanical two rope clamshell grabs are equipped with lugs, which can be directly connected to the lifting rope shackle of the crane.

Qanday qilib to'g'ri tutqichni tanlash kerak
- Maqsadingizni aniqlang:
Variantlarni ko'rib chiqishdan oldin, iltimos, maxsus talablaringizni aniqlang. O'zingizdan so'rang:
- Siz qanday materiallar bilan shug'ullanmoqchisiz? (log'lar, metallolom, tosh va boshqalar)
- Tutqich qanday vazifalarni bajaradi? (Yuklash, saralash, demontaj qilish va h.k.)
- U qanday turdagi qurilmaga ulanadi? (Gantry kran, ko'prikli kran)
- Siz ushlagan materialning solishtirma og'irligi qanday? Tutqichning kublari soni?
Tutqich bilan jihozlangan kraningizning tonnaji qancha?
Qo'lga olinadigan materialning xususiyatlariga ko'ra, tortish odatda to'rtta asosiy turga bo'linadi: engil, o'rta, og'ir va o'ta og'ir.
