Series ZA Basic Balancer
Refer to Dwg. MHP1899 in the Parts Information Manual.
Place balancer on a clean, sturdy work surface with end cap upright. Remove ZA control kit from its package and make certain O-ring (11) is in
place on back of manifold. Install manifold (1) with Mounting screws and Lockwashers (2 and 3).
Control Hose Installation
The control hose is pre-assembled to the control handle, but it must be attached to the manifold.
Control hose assemblies may either be gray and black straight hose, or yellow and black coiled tubing. The gray hose or yellow tube (6) must be
connected to the downside of the manifold. The black hose (5) must be connected to the up-side of the manifold.
Operational Adjustments
Prior to performing operational adjustments or servicing make sure air supply is off. Press down lever until wire rope is slack.
1. Install manifold to end cap.
2. Connect black UP hose to UP port on manifold.
3. Connect gray hose/yellow tube (handling device applications) to DN port on manifold.
When wire rope is winding, air is entering the balancer through both the up and down flow controls. Therefore, down flow control
also affects the up speed when it is set for a minimal down speed.
4. Connect main air supply to right side port of manifold.
5. Turn on main air supply. Adjust regulator to required air pressure.
6. Rotate hook balance screw clockwise slowly until wire rope begins to raise, move to the full up position, ensure Z-Brake does not engage.
7. Install load hook and handling device to wire rope in required position. Refer to "Lash Up" Section on page 8.
8. Rotate UP flow control clockwise until snug.
9. If wire rope is slack, ensure the Z-Brake does not engage.
10. Feather UP lever until tension is applied to wire rope, then fully depress UP lever until load is in the full up position.
11. Depress DN lever and check speed.
12. Adjust DN flow control on manifold counterclockwise to increase speed, clockwise to decrease speed, until desired speed is achieved.
13. Lower to bottom of normal travel with tension on wire rope.
14. Adjust UP flow control on manifold counterclockwise to increase speed, clockwise to decrease speed, until desired speed is achieved.
Series BA Balancer
150 lb. (68 kg) Capacity
Manifold Installation
Refer to Dwg. MHP1908 and Dwg. MHP1259 in the Parts Information Manual. Place balancer on a clean, sturdy work surface with end cap
upright. Remove BA control kit from its package. Check to be sure O-ring (3) is in place on the back side of the manifold (2). Install manifold to
end cap by using the four mounting screws and lockwashers (4 and 5) provided. Regulator is supplied with a hex nipple and a check valve. The
hex nipple should be threaded into the hole on the manifold Connect air supply to check valve.
Arrow on check valve must be pointing toward balancer. If installed backwards balancer will not function.
Operational Adjustments
Prior to performing operational adjustments or servicing make sure air supply is off and wire rope is slack.
1. Connect regulator to balancer.
2. Rotate regulator adjustment knob counterclockwise until it stops.
3. Turn on main air supply. Adjust regulator to required air pressure.
4. Rotate adjustment knob clockwise slowly until wire rope begins to raise, move to the full up position. (Ensure the Z-Brake does not engage -
150 lb. (68 kg) units only).
5. Install load hook and tooling or fixture to wire rope in the required position. Refer to "Lash Up" Section on page 8.
6. Rotate adjustment knob clockwise until load is suspended.
7. The correct setting will require equal effort to lift and lower the load.
8. If unit is required to raise the load out of the way, turn adjustment knob clockwise until desired speed is achieved.
9. Tighten jam nut just above adjustment knob to maintain proper setting.
Series BA Z-Servo Control
200, 350 and 500 lb. (90, 158 and 227 kg) Capacity
Refer to Dwg. MHP1909 in the Parts Information Manual.
Z-Servo Installation
Refer to Dwg. MHP1354 on page 14, A. Adjusting Ring; B. Air Exhaust; C. Wire Rope. Mount balancer on overhead suspension, with wire rope
fully extended. Determine proper wire rope location for Z-Servo, refer to "Load Hook Lash Up" Section on page 8. Attach Z-Servo valve to wire
rope.
