AIM HL Quick Couplers

New Hydra-Lock (HL) hydraulic quick couplers offer a dependable, proven design with safety in mind, for use with OEM configured attachments.  The AIM HL couplers feature a simple design, in which no pin removal is needed for an easy exchange of a variety of attachments, making your excavator a multi-capable machine.  This system eliminates hundreds of on-site man hours spent changing manually configured attachments.  Specific features include:


·        One-man operation, allowing the easy exchange of attachments.

·        No special modifications needed for attachments such as buckets, hammers, rakes, or rippers.

·        All couplers include a durable lifting hook.

·        Built-in safety check-valves help eliminate electrical fault and human errors that cause accidents.  The cylinder will not disengage when pressure is lost in the hydraulic line.  A warning buzzer for the cab is also standard.

·        Multi-position manual safety pin for added safety.


These couplers were designed to minimize the negative effect on breakout force due to the increase in the tip radius dimension.  .  For additional information contact the manufacturer direct at 1-800-803-3365 or browse online at
