SAFER POSI LOCK PULLER OPERATION FOR MANUAL PULLERS: 1. Make sure that all items being pulled are supported by a means other than the puller. NO LOOSE PIECES!!! 2. Before each use, lubricate the center bolt of the puller with a graphite-based lubricant. 3. To operate the puller, grasp the puller with one hand and…

SAFER MECHANICAL PULLER OPERATION: 1. Make sure that the spindle is clean and greased before use. 2. The shaft must have a center hole. If it does not, use a shaft protector 3. Tighten strap bolts to hold jaws lightly in place. 4. Position the puller. 5. Tighten the spindle slightly by turning the spindle…

OPERATION: Before lifting a load. The cylinder must be securely attached to the toe lift base. Keep the contact surface between the toe lift and the load clean. The contact surface must be free of oil, grease, or dirt to avoid slippage. Before lifting a load make sure that that the contact surface of the…

Enerpac machine lifts are built from a steel housing and a single-acting, spring return hydraulic cylinder. Powered by an external hand or electric pump, the cylinder plunger moves and actuates the machine lift. The support feet on the machine lift must be extended to provide maximum stability. To place the load skates, the load must…

HEAVY DUTY CATERROLLER™ LOAD SKATES STRAIGHT-LINE MOVES: Skates must remain parallel to each other to assure easiest motion in any one direction. Rigid-top skates will stay in position as placed, but swivel skates may be knocked out of alignment if the move is over a rough or dirty surface. Care should be taken, floors cleaned,…

HEAVY DUTY CATERROLLER™ LOAD SKATEs LIFTING LOADS: 1. Use load-lifting devices with a capacity exceeding the load weight and with enough lift height to safely install skates under the load. 2. Refer to the selection chart in the Enerpac catalog or the instruction sheets included with the skates for dimensions and skate load capacities. 3.…

HEAVY DUTY CATERROLLER™ LOAD SKATES FLOOR CONDITION AND PATHWAY CLEARANCES: 1. Floors or other path surfaces must be clean and free of cracks or holes, which can hinder skate travel. 2. Check and verify all load-bearing capacities of all floors or pathway surfaces. Ramps or other structures should be reinforced to handle the load. 3.…

HEAVY DUTY CATERROLLER™ LOAD SKATES CAUTION: Swivel type skates must be checked during moves to ensure parallel alignment under the load. WARNING: To prevent possible injury and equipment damage, do not exceed the rated capacities of the skates. LOAD REQUIREMENTS: 1. Determine the number of skates needed by calculating the total weight including support timbers,…

HEAVY DUTY CATERROLLER™ LOAD SKATES Load skates consist of a rigid steel frame with saw-toothed edges, a center guide plate and a set of rollers. The rollers are connected by link chain on either side with a master link for separating them. Each roller turns independently and the entire set rotates around the guide plate. Loads…

STB-SERIES PIPE BENDER SETS ASSEMBLY: 1. Fully thread the hydraulic cylinder into the cylinder support block on the bending frame. 2. Make sure that the saddle is fully threaded into the plunger fully hand tight. 3. Make all hose connections between the cylinder and hydraulic pump. Make sure that the coupler(s) are fully hand tightened.…

STB-Series hydraulic pipe bender sets are designed to provide quick, safe, and wrinkle-free bending of schedule 40, 80, 160, and DEH pipe in 1⁄2″ through 4″ sizes. STB-Series pipe bender sets include the Enerpac hydraulic cylinder, hose, and manual, air, or electric powered pump. Sets are also available without hydraulics. The bending frame and shoes are…

All hydraulic systems should have a gauge. The gauge is the window to the hydraulic system. In addition to indicating the operating pressure, the gauge can also warn you that something is going wrong. IN A LIFTING SITUATION THE GAUGE WILL READ AS FOLLOWS: • The gauge will not show much of a pressure rise…

The advantage of using couplers rather than threaded connections is that you can quickly make and break hydraulic connections. The disadvantage of using couplers is that they are frequently the point at which dirt enters a hydraulic system. OBSERVE THE FOLLOWING WHEN USING COUPLERS: • Make sure couplers are clean before making any connections. Use…

USE THE FOLLOWING INFORMATION TO AVOID PROBLEMS WITH HOSES: • Do not kink or tightly bend hoses. This will damage the wire braid. The minimum bend radius is approximately 12 cm [4.5 inches]. This means there should be no less than 24 cm [9 inches] between the straight sections. • The most sensitive part of the…

Hand pumps are a convenient, portable source of hydraulic power. They are designed to be stable during operation. For best performance, operate the pump handle at moderate speed. When the handle gets hard to push at high pressure, take short strokes. The maximum leverage is obtained in the last 5 degrees of stroke. Adding an extension to the pump handle…

KEEP THE FOLLOWING IN MIND WHEN USING A CYLINDER: • The base of the cylinder should be fully supported. Where applicable, use a cylinder base for added stability. Do not weld or otherwise modify the cylinder to attach a base or other support. • The saddle on the end of the plunger should make full…

The cylinder (or ram) operates much the same as the jack, except that it is more versatile. Since the pump is separate, the cylinder can be used in several positions. By adding extensions and attachments to the cylinder, you can create a wide variety of hydraulic tools. The saddle in the plunger serves two important purposes. It protects the…

The jack is one of the oldest and most familiar pieces of hydraulic equipment. This familiarity contributes to misuse which can lead to personal injury. The jack is a load lifting device and should never be used as a load holding device, especially when a person will be going underneath the supported load. KEEP THE…

This is a brief explanation of some of the forces at work while you are lifting a load with a jack or cylinder. The main line of force is through the center of the plunger. The weight should be distributed as close to this center line as possible. The entire base of the jack or…

The jack is one of the oldest and most familiar pieces of hydraulic equipment. This familiarity contributes to misuse which can lead to personal injury. The jack is a load lifting device and should never be used as a load holding device, especially when a person will be going underneath the supported load. It is…

High pressure hydraulic tools are designed to be operated up to 700 bar [10,000 psi] hydraulic pressure. Most fluid power systems operate at 210 bar [3,000 psi]; with some going up to 350 bar [5,000 psi]. The hydraulic pressure is the pressure that builds up inside the equipment (jacks, pumps, cylinders, hoses). Any components connected…

Promoting personal safety is the primary goal of the Think Safety Kit. Whether you work in maintenance or production; power plant, shipyard, mine, shop floor, or construction site; we hope you will learn to use your hydraulic tools safely. When you practice safety, you also benefit by being more efficient and by increasing the useful life of your tools.…

Finding the right company to test your lifting equipment can be quite difficult. Choose one that has people who know what they are talking about so that any questions you may have can be answered promptly and clearly, however technical or seemingly trivial. For instance, hydraulic jacks can be tested on site by fully qualified…

The Space shuttle Endeavour will today launch for the final time. It is the end of an era and the passing of the space shuttle is similar to the end of the Concorde, both were very enigmatic transport and both ahead of their time. In the lead up to today’s launch, there were a few…

At CeMAT 2011, Cargotec unveiled their new DCG90-180 range of Kalmar lift trucks, all featuring the new ‘G’ counterbalancing equipment. As all the visitors to the show can testify, this new range of forklift trucks, with capacities ranging from 9-18 tonnes, and the first of Cargotec’s G generation material handling range of equipment was a…
