- 1. In combination with several cylinders (100 ton 70 ton), pullers (150 ton 50 ton 30 ton) etc., this hydraulic pump is used for a wide range of operations.This is the most fundamental tool for the construction machinery maintenance.
- 2. This pump is designed to be easily transported by separating the attachment from the pump. Thus, it is most suitable for field services, as compared with conventional presses.
- 3. As four kinds of scales are notched in one gauge, the operating tonne of each cylinder and puller can be measured and the exact operations based on the specified pressures can be performed.
- 4. The sequence valve is installed in the pump, which controls the movement of the ram. When the load is light, 129cc oil per stroke is delivered by the action of the low pressure piston and the ram moves fast, and when the load becomes heavier, the oil pressure exceeds 25 kg/cm2 and high pressure pump operates automatically and 4.6cc oil per stroke is delivered and the operation of the handle becomes lighter.
- 5. By changing the lever of the four-way valve both actions of pushing and pulling of the cylinder ram can be achieved.
- 6. As the special automatic sealing coupler is used for removing the cylinders and pullers from the pump, the flow out of high pressure oil can be eliminated.
- 1. Cylinder, ram and piston are made of special steel and the weight is relatively very light.
- 2. Both operations for pushing and pulling can be performed.
- 3. These cylinders are used with electric or hand-operated pump (MT-800PE, 800PEC or 700P) for removing and installing the track master pin and sprocket.

- 1. The operation for pulling direction can be achieved by utilizing the center hole as well as the operation for pushing direction. (All pullers)
- 2. By screwing in the attachments using outer or inner thread, these pullers can be applied in the narrow space. (MT-50CC, MT-30CA)
- 3. The range of usage can be widened by adopting the spacers on the ram.
- 4. These pullers are used with electric or hand operated pump. (MT-800PE, 800PEC or 700P)
