Hydraulic tools specialist, Enerpac, announces the new PPH-Series Hydraulic Pin Puller, providing an efficient, safe and versatile method for removal of joint pins during the maintenance of heavy machinery.

These complete kits use hydraulic power to remove joint pins on vehicles, excavators and heavy machinery used in construction, mining, bogie and truck pin removal for rail and in stationary equipment found in manufacturing facilities.

Until now, operators have relied on pin removal using unsafe methods, such as torching, lancing, or hammering, all of which risk irreparable damage to the joint pin, resulting in extra costs and leading to longer downtime. With a pulling capacity of 40-67 t, the PPH-Series Pin Puller provides a safer and more efficient removal of joint pins up to 302 mm long. It uses a powerful, Enerpac hydraulic cylinder to extract pins with precision and minimal damage, allowing a single operator to remove a multitude of joint pin sizes easily.

Supplied in a portable, wheeled carry case, the PPH-Series Pin Puller Kits, PPH40 and PPH66, are ideal for mastering a diverse range of pin-pulling tasks. Each set includes three stacking and locking patented C-Sleeves, with the option of adding an extra two for longer pins up to 508 mm long. The C-shape design creates a fitment around the flag of heavy machinery pins, providing a precise and safe pin removal. Improving operator safety, each kit contains a shackle for lifting via a crane or lifting system. The column sections have multiple hoist points, designed to give the user more control over the balance of the tool while it is suspended. The kit also contains a Quick Nut for fast attachment to threaded rods, with alternative thread sizes available to purchase separately.

‘Quick Nut’ for damaged nut threads

With existing solutions using regular threaded nuts, that require time to run down the rod and cannot be used on damaged treads, the PPH-Series kits are engineered to streamline even on the most demanding pin pulling projects. The innovative split Quick Nut makes it easier and faster to manipulate damaged threads. The easy one-handed closure is quick to assemble around a rod and avoids running the nut over damaged threads.

Ejnar Christensen, National Accounts Manager, Enerpac, said: “Safety on the job site is paramount, which is why these kits offer a safer alternative than old-school, traditional methods involving sparks, heat, hammering and loose parts. We wanted to provide a safe and efficient way for a single operator to extract pins from construction vehicles that eliminated damage to parts, but also provided a lightweight and potable tool that was practical to move about on-site. The transport and assembly of the PPH-Series Pin Puller Kits is made easier by the robust aluminium construction of the Enerpac Hydraulic Cylinder.”

Each PPH-Series Kit includes three column sections that lock together. Multiple column sections can be stacked together depending on the length of the joint pin. Up to maximum 5 Column Sections can be locked together.
