HFP Mechanical Grab with Stiff Arm – 2.5–4.5T Excavators | 35mm / 40mm Pin – $2,290 inc GST
The HFP Mechanical Grab with Stiff Arm is engineered for 2.5–4.5 tonne excavators running 35mm and 40mm pin configurations, delivering reliable, low-maintenance material handling performance across tree work, landscaping, site clean-ups, light demolition, and general material movement applications.
Designed for operators prioritising simplicity, durability, and controlled operation, this mechanically actuated grab delivers dependable gripping performance without requiring auxiliary hydraulics.
Utilising excavator bucket curl action for actuation, the mechanical grab system reduces hydraulic complexity while maintaining excellent gripping capability across irregular and bulky materials.
The included stiff arm and mounting bracket provide stable operation, correct geometry, and controlled material handling performance in demanding commercial environments.
Designed for Australian conditions and suited to contractors, hire fleets, councils, OEM applications, and civil construction operators requiring durable long-term attachment performance.
Backed locally with parts, technical support, and after-sales service.

Fitment Confirmation Required
To ensure correct fitment and operation, please provide:
Machine make
Machine model
Pin diameter
Pin centre to pin centre
Width between ears
Quick hitch type
This attachment is custom-configured to suit your excavator setup.
Final configuration and fitment are based on the specifications supplied by the customer.
Machines fitted with quick hitches may require additional clearance considerations depending on hitch design and geometry.
Excavator Size & Fitment Notes
Excavator tonnage ranges listed are intended as a general guide only.
Machine operating weights, linkage geometry, quick hitch configurations, arm design, and intended application can vary significantly between manufacturers and models.
Machines within the same tonne range may utilise different pin sizes, pickup geometries, and linkage configurations depending on manufacturer design and operating requirements.
Larger pin configurations and heavier-duty hitch setups may require reinforced ear configurations, heavier structural components, and larger grab assemblies to ensure safe operation and long-term durability.
Some machines may therefore fall into a larger attachment class than their operating weight alone would normally suggest.
Factors affecting sizing can include:
Pin diameter
Pickup geometry
Hydraulic hitch configuration
Lift capacity requirements
Machine stability
Material type and operating environment
For this reason, all grabs are configured based on the machine specifications supplied at the time of order to ensure correct fitment, structural suitability, and optimal performance.
