When using a wood grab to handle large amounts of waste wood, it is necessary to consider the size, material characteristics, and working environment of the waste wood, select the appropriate type of wood grapple, and follow the safe operating specifications.
Select the wood grab type based on the characteristics of the waste wood.
For large-sized waste wood (such as beams, columns, and door frames), choose an orange peel hydraulic wood grapple. Its wide teeth provide a secure grip on long, thin logs, preventing them from slipping.
For example, when handling whole beams from construction waste, an orange peel wood grab can simultaneously grasp multiple beams, thereby improving efficiency.
Small wood chips or sawdust
Use a dense-tooth grapple or a rotating grapple. The dense-tooth design prevents spillage of fine wood chips, and the rotation function allows for easy adjustment of the wood grab angle.
Mixed waste materials (such as wood scrap containing metal) require a wood grabber equipped with a magnetic suction device, or a metal detector should be used to separate impurities beforehand to avoid damage to the wood grabber.
Operation Procedures and Safety Standards
Pre-operation Inspection
Confirm that the hydraulic system is leak-free when the wood grab is connected to the excavator.
Check the grip fatigue. If fatigue exceeds 30%, disengage the gripper to prevent slipping during extraction.
Grasping and Handling
Large Scrap Wood: Insert the grab teeth vertically into the ends of the wood and close the grip slowly to avoid excessive force that may break the wood.
Small Scrap Wood: Lower the wood grab bucket close to the ground and slowly close it to collect the wood chips and prevent dust.
Composition: Use a magnetic device to mix and separate metals first, then absorb the particles.
Stacking and Transportation
Stack wood scraps in a designated area, no more than 3 meters high, to prevent collapse.
Use a closed truck or a CO2 net for transportation to prevent wood chips from scattering and contaminating the environment.
