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.

Jinsi ya kuchagua kunyakua sahihi
- Fafanua kusudi lako:
Kabla ya kuzama katika chaguzi, tafadhali fafanua mahitaji yako mahususi.Jiulize:
- Je, ungependa kushughulikia nyenzo gani? (Magogo, vyuma chakavu, mawe, n.k.)
- Je, unyakuzi utafanya kazi gani? (Kupakia, kupanga, kubomoa, n.k.)
- Je, kitaunganishwa kwa aina gani ya kifaa? (Gantry crane, crane ya juu)
- Je! ni uzito gani mahususi wa nyenzo unayonyakua?Idadi ya cubes za kunyakua?
Je, ni tani gani ya crane yako iliyo na vifaa vya kunyakua?
Kulingana na sifa za nyenzo zinazochukuliwa, kunyakua kawaida hugawanywa katika aina nne za msingi: nyepesi, za kati, nzito na nzito sana.
| Aina ya nyenzo za kunyakua | Kunyakua nyenzo | Uzito wa uwezo (t/m³) |
| Mwanga | Coke, slag, nafaka, viazi, chokaa cha anthracite cha ubora wa kati, saruji, udongo, changarawe, udongo, matofali yaliyovunjika, nk. | 0.5~1.2 |
| Kati | Peat, vipande vikubwa vya makaa ya mawe ya anthracite, makaa ya mawe yaliyounganishwa, udongo, chokaa, changarawe, chumvi, changarawe, matofali, bauxite, flakes ya oksidi ya chuma, saruji, mchanga na matofali katika maji, nk. | 1.2~2.0 |
| Nzito | Chokaa, udongo mzito, madini madogo na ya kati, miamba migumu, oksidi ya chuma yenye umbo la fimbo, madini ya chuma, unga wa makinikia wa risasi n.k. | 2.0~2.6 |
| Uzito kupita kiasi | Ore kubwa, ore kubwa ya manganese, unga wa madini ya risasi, nk. | 2.6~3.3 |
- Utangamano wa vifaa: Hakikisha kunyakua kunaendana na vifaa vilivyopo.
- Mazingatio ya Bajeti: Bei mbalimbali za kunyakua ni tofauti.Sawazisha bajeti yako kulingana na utendakazi na uimara wa kunyakua.
- Maoni na mapendekezo: Tafiti mtandaoni, soma hakiki za watumiaji, na utafute mapendekezo kutoka kwa washirika wa tasnia.
- Nenda kwa mtengenezaji wa crane kwa ukaguzi na majaribio kwenye tovuti kabla ya kununua: jaribu kunyakua chini ya hali halisi kadri uwezavyo.Tathmini utendakazi wake, urahisi wa utumiaji, na utendakazi kwa ujumla.
Keep in mind that choosing the right grab requires a balance between functionality, safety, and cost.By considering these fac
