GRAPPLES

admin — Tue, 25 Oct 2011 05:11:43 +0000

The Grapples are constructed as follows: The claws which serve to pick up the rocks, are attached by means of a shaft to the stick of the excavator. The shaft serves also as turning point of the upper claw. The claws are made of high wear resistant steel. The upper claw is driven by the original cylinder of the excavator to the claw. The claw can be opened and closed by pulling the cylinder rod in or out.

Because of all the different stick executions of the excavators, these grabs are manufactured according to the specifications of the customer. Executions are available upon request.

		The grabs are manufactured at customers specifications and can be manufactured in any weight execution and capacity required.

TAGLINES

admin — Tue, 25 Oct 2011 08:30:09 +0000

The Tagline is made to hold a grab steady regardless of boom angle while the grab and its load are suspended in air. The Tagline’s operation is completely automatic after installation. The Tagline operates on a coil spring system that maintains constant, positive tension on a grab. The unit mounts on a crane boom and consits of a cable reel, cable wire, two spring-loaded cylinders and a bell guide fairlead. The fairlead requires no sheaves, pins or lubrication.

Depending on the size and weight of the taglines can be executed in:

Single Barrel
Double Barrel
Triple Barrel

ELECTRO HYDRAULIC CLAMSHELLS

admin — Mon, 24 Oct 2011 20:19:26 +0000

The Electro Hydraulic (Motorised) dual scoop Clamshell is specially designed for charging and discharging bulk materials and is to be fitted on cranes with one single drum (ship board cranes).

If the ships cranes are not executed with accessories yet, The Grab Specialist can also supply accessories which need to be mounted on your ships cranes for operation of the grabs.

Sometimes when you for example are chartering various ships it is not allowed to mount the accessories on the ships cranes, therefore we have also designed an alternative: “Deck Towers”. The Deck Towers just have to be put on the deck of the ship and are equipped with all necessary accessories for operation of the grab. The Deck Towers are executed with extremely strong magnets and can just be put on the deck of the ship.

There are 2 types: Electric-Mechanical Deck Towers or Motor Driven Deck Towers. The most suitable type depends on the required winding length of the cable and/ or the kW of the motor.

Optional

The shells can be executed with spill/ kick plates to reduce capacity. This will give you an advantage when bulk materials with various densities are (dis)charged. This can be calculated to the biggest capacities possible in combination with the lifting capacity of your crane.

ELECTRO HYDRAULIC ROUND NOSE GRABS

admin — Mon, 24 Oct 2011 21:46:21 +0000

The Electro Hydraulic round nose grab is specially designed for heavy-duty dredging and digging purposes. For very hard soils mixed with rocks. The turning points are equipped with heavy duty bearings. The bearings are double sealed to prevent entering dirt into the bearings. The inner side of the scales is smooth, without any abrupt transitions. This minimises the resistance during the digging in to the bottom and also makes it easier to unload sticky materials, like clay. The knives are manufactured in a round shape for more strength and more impact into the very hard bottom grounds. For hard layers and different materials, we recommend knives with teeth. The grabs are executed with knives with interchangeable teeth.
