Protected internal hoses
In all of STEPA’s double telescopic forestry cranes, the hoses are internally routed in the arm system, providing great protection against damage. This means that work can be carried out safely, minimising the risk of damaging the hoses on the knuckle boom with machinery.
Robust & protected flap-down stabiliser with non-return valve
STEPA’s flap-down stabiliser is stronger and better protected due to its closed-body design. The ideal design of the flap reduces the pivot radius and provides a short support with a large reach.
EPSILON’s patented link-rotator-combination with internally routed hoses provides maximum protection during work for hoses between the crane and the grapple.
Cathodic dip-painting & powder coating
All main components in STEPA forestry cranes & forestry trailers are cathodic dip-painted and powder coated. This high-quality type of paintwork guarantees that STEPA products will still look good after years of use and helps keep the resale value high.
Crane column with cast iron lower section
The use of a high-strength crane column base guarantees that the operator will have a safe working environment even after years of use as damage to the crane column is ruled out.
Spherical roller bearings in the cast iron column
All STEPA cranes with the cylinder slewing system from EPSILON are equipped with a large, maintenance-free spherical roller bearing as the lower crane column mounting. This takes on all loads and at the same time guarantees that the crane can be controlled with extreme accuracy even when it is load-bearing.
Double slewing system
All STEPA cranes with a cylinder slewing system from EPSILON have a bottom-mounted double slewing system that runs in an oil bath and is therefore maintenance-free. The two solid racks have a strong slewing torque and long durability even with the toughest jobs.
Z crane articulation
The articulation between the crane column and the main boom assures the main boom’s constant working speed throughout the entire movement range. The lifting capacity in the upper boom settings is also up to 60% greater than in cranes without an articulation.
L crane articulation
The articulation between the main boom and the knuckle boom assures the main boom’s constant speed throughout the entire movement range.
All STEPA cranes are fitted as standard with an emergency stop switch, hose breakage throttles, seat stop switch, safety non-return valve on the stabiliser, a convenient and safe step with non-slip entrance, a large control station and much more. As such, the STEPA cranes are among the safest in the industry.
All STEPA log grapples have large bearings and sophisticated grapple geometry. They are available in three sizes.
