Frequently Asked Questions
How high do I need to lift the mixer?
Usually a clearance of 6” from the bottom of the mixer shaft to the top of the container is used for clearance. The vertical lift of the mixer is generally determined by the mixer’s shaft length and the tallest container. The lifter should lift the mixer high enough to clear the lower impeller and bottom of the shaft from the top of the tallest container.
Which is better, air lifting or electric lifting?
The standard air/hydraulic version of the lifter has many advantages over using an electrically powered lifter. However, either type can be supplied. The air/hydraulic version is usually lower in cost than the electric version. They are inherently explosion proof as there are no electrical connections. The air/hydraulic version can be used with any type mixer. Pneumatically powered mixers are usually less in cost, are variable speed, and are inherently explosion proof.
What are the pros and cons of using casters for mobility?
Anchoring the lifter to a fixed point eliminates the possibility of over turning. Care must be taken with units mounted on casters to prevent tipping. Lifters with casters have a wider foot print to provide stability and they must be in the down position before being moved. For lifters with casters, passageways and doors must be large enough to accommodate the lifter with the mixer attached. The lifter can be tall enough to interfere with the top of the doorway, and a power source must be supplied at each operating location for lifters with casters.
Competitive units are available using boat winches and wire rope. Will you supply this design?
Safety is our primary concern when using a mixer lifter. The cheaper units can have the winch fail or the wire rope break. When this happens the mixer drops instantly. This can damage equipment or injure the operator.
Because our unit utilizes an air/ hydraulic system, the unit will lower slowly and safely as the hydraulic fluid is displaced if the air supply is cut off or there is some type of mechanical failure. Because of safety concerns the design utilizing winches and wire rope will not be supplied.
What type mixer mounting is best for tote tank applications?
Our design places the mixer in the center of the tank opening for vertical shaft installation. Our standard design accommodates clamp, cup-plate, or fixed mounting. Clamp mounting is the least expensive design. Special mounting requirements can also be supplied.
One version of the lifter design eliminates the legs and attaches the lifter directly to a wall or other vertical support. The support legs on the lifter extend out too far at the floor and I am tight on room. There have been customers who use a structural beam anchored to the floor to support the mixer lifter.
On electric units can I use a VFD drive?
The mixer lifter can be supplied with a VFD mounted in a control panel on the lifter frame. If you chooses to supply the VFD, it can be mounted separately and wired into a control panel mounted on the lifter. On units with casters, a bracket to mount the customer supplied VFD can be supplied.
Explosion Proof Applications?
It is strongly recommended to use an air/hydraulic lifter and a pneumatic mixer with an air valve to control the mixer speed for all explosive proof applications. If an explosion proof electric design is required, refer the specifics to your distributor for pricing.
Can you match our company paint colors?
We no longer provide painted or coated units. Our standard is a 304SS frame with stainless push lock fittings on the air and hydraulic lines. The hydraulic cylinder and air/hydraulic tank are supplied with the manufactures standard finish with aluminium valving. Casters can either be steel or stainless. We can supply all items in stainless if desired, so just let us know what your needs are.
Will you supply stainless steel units?
Yes. As standard, the frame, casters, hardware, and most fittings are made of stainless steel. The hydraulic cylinder, air tank, tubing, and control valves can also be stainless steel. For more details, contact us.
What kind of safety features are on the mixer lifter?
Rotating mixer blades outside the mixing container are potentially dangerous. All but the simple mechanical assist mixer lifters contain two proximity switches that prevents operation of the mixer unless it is in the lowered position and the tank is in contact with the lifter. Our units utilize spring loaded lever valves that must be activated together to raise or lower the unit. This occupies both of the operator’s hands and minimizes the possibility of hand injury when raising or lowering the mixer. We supply a safety strap to hold the lifter against the mixing container. This insures that the lifter will not move in relation to the tank. Movement could cause damage to the mixer or tank during mixing. On units with casters, two of the casters have brakes. When the brakes are set it lessens the possibility of the lifter moving.
