Versatility- Variable pin center design allows you to easily pick up and swap the widest range of attachments.- Ability to reverse buckets to allow the operator to excavate against walls and under pipes.
Productivity- DEVELON couplers can save you 25% of total machine operating time compared to direct mount.- Operator can change attachment from the comfort and security of their cab.- A more compact design means improved tip radius which increases breakout force.
Durability- Our simple design has no greasing requirements, less maintenance and replacement parts which guarantee you a hassle free coupler.- Manufactured using extra high strength steel to increase durability while optimizing weight to enhance excavator performance.
Safety- Front safety lock is forced on by spring which retains the attachment in case of misconnection.- The rear safety lock is the secondary safety feature backed up by two powerful springs which retains the attachment rear pin in case of cylinder failure.- Powerful spring activated safety locks work in all dirty environments unlike gravity systems.
