Excavator Rotating Grapple

Production Description

HT Excavator Rotating Grapple, also called "Excavator Log Grab, Timber Grab", adopts Q690 High Strength Steel and advance rotating motor. 360-degree clockwise or anticlockwise rotation and the rotation speed can be controlled by operator, special rotary gears are used to prolong lifespan and lower the cost, fit for all operations where there need grappling and loading, such as stone, timber, waste, tube operations, garden and stone laying projects

Advantages

1. Material:

1) Entire jaw structure is manufactured of quenched and tempered Q690 High Strength alloy steel, 130,000-psi min. yield 360-440
BHN. Instead of traditional Q355b.
2) The tine tips are 175,000-psi min. yield 450-550 BHN. Chromium plating.

2. Motor:
1) Motor drive adopts the design of symmetrical double support,strong shcok resistance, avoiding axle breakage and oil leakage.
2) Pedestal adopts sealed type design, better protect the rotary drive.
3) Output Torque:4 kN.m-8.5kN.m(6272lbf.ft)
Holding Torque 38kN.m-105kN.m(78000lbf.ft)
Moment Torque 26kN.m-203kN.m(150,000lbf.ft)

3. Strengths:
1) Sealed type rotary drive solve the oil leakage problem, only required light greasing(80g of grease) once 6 months(unlike most
of the product on the market needed greasing everyday) and better protect the product.
2) Motor drive adopted symetrical double support design, reducing the bearing load and extend service life.
3) The jaw structure is manufactured of Q690 High Strength Alloy Steel, lighter weight with twice of the strength comparing with
Q345(normally used on the market)
