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.

Hvordan velge riktig grip

  1. Avklar formålet ditt:

Før du fordyper deg i alternativene, vennligst avklar dine spesifikke krav. Spør deg selv:

  • Hvilke materialer vil du håndtere? (Tømmerstokker, skrapmetall, stein osv.)
  • Hvilke oppgaver skal grabben utføre? (Lasting, sortering, demontering osv.)
  • Hvilken type enhet vil den bli koblet til? (Portalkran, traverskran)
  • Hva er egenvekten til materialet du griper?Antall kuber av gripen?
  • Hva er tonnasjen til kranen din utstyrt med grip?

I henhold til egenskapene til materialet som gripes, er gripen vanligvis delt inn i fire grunnleggende typer: lett, middels, tung og supertung.

Type materiale som skal gripesTa tak i materialeKapasitetsvekt (t/m³)
LysKoks, slagg, korn, poteter, middels antrasittkalk, sement, jord, grus, leire, knuste murstein, etc.0.5~1.2
MediumTorv, store biter av antrasittkull, komprimert kull, leire, kalkstein, grus, salt, grus, murstein, bauxitt, flak av jernoksid, sement, sand og murstein i vann, etc.1.2~2.0
TungKalkstein, tung leire, små og mellomstore malmer, hard bergart, stavformet jernoksid, jernmalm, blykonsentratpulver, etc.2.0~2.6
OvervektigStore malmer, stor manganmalm, sedimentært agglomerert blymalmpulver, etc.2.6~3.3
