Trimming grabs are a new type of bulk grab, which is suitable for double-drum cranes for loading and unloading iron ore, coal, bulk fertilizer and other materials.
Trimming Grabs are characterized by novel structure, easy operation, light weight and high loading ratio. When the trimming grabs are loaded with iron ore, the ratio can reach 1:2.5.
The opening and closing strokes of the trimming grabs are short.
Advantages of Trimming Grabs
1.High grab ratio
2.High efficiency: Not only does improving the gripping ratio greatly improve production efficiency, but the gripping force of the scissor grab is small when it is fully opened and starts to grab the goods. With the closing of the grab, the digging force continues to increase, which is just the same as the digging force required to grab the goods, so the gripping efficiency is greatly improved. Only a smaller opening and closing stroke is required to complete the closure, saving closing and opening time and improving efficiency.；
3.Conducive to clearance: due to the large opening of the scissor grab, the grabbing area of each bucket is 60% higher than that of the long strut grab, and no excavator or stacker is required to complete the clearance work.
4.Low failure rate: Due to the small number of shear grab pulleys and fewer pins, this reduces the failure rate of some wearing parts.Due to these advantages of scissor grab, many large bulk cargo grabbers in foreign ports have adopted scissor grab.

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.
Kumbuka kwamba kuchagua kunyakua sahihi kunahitaji usawa kati ya utendakazi, usalama, na gharama.Kwa kuzingatia mambo haya, utapata mtego kamili ambao unaweza kuongeza tija na kuhakikisha uendeshaji mzuri.
