)
double linked unit
The AL-1132-220 is a two post parking hoist that
developed through continuous research. The hoist
enjoys great popularity with the features of simple
structure, easy assembling and space-saving.
The hoist is mainly consists of posts of two sides,
carriage of two sides, and wave plate platform. The
left and right post can be used in common. The left
and right carriage can from double-linked or
multi‐linked hoist with the column at
random.

Installation & Operation Manual
4.1.3 Check the working environment of the hoist. Don't use the hoist in adamp environment. Keep good
ventilation and enough light of the use area.
4.1.4 Only trained person can operate the parking equipment. The staff untrained should keep away from the
working area. All the staff without training is forbidden to operate the hoist.
4.1.5 Motor must be grounded to avoid electric shock.
4.1.6 Turn power off when installing to secure the safety as there is high voltage on the power unit.
4.1.7 Always pay attention to your surroundings to avoid injury.
4.1.8 Operate the equipment in normal way. Do not modify the equipment in any way or use aftermarket parts
which are not purchased from Advance AutoQuip or its authorised repairers.
4.1.9 Prohibit modifying any parts.
4.1.10 Safety locking device should be well protected.
4.1.11 When lifting or lowering the vehicle, keep personnel away from the area.
4.1.12 Keep all other equipment away from the hoist area.
4.1.13 Warning: The working area should be not flammable as there is electric spark when the switch works.
4.1.14 this mark means safety warning.
4.1.15 Keep the equipment clean and keep regular maintenance. Appropriate lubrication and maintenance is
important for safety and warranty.
4.1.16 Keep handle and button clean and dry, avoid contamination of oil and grease from the hoist.
4.1.17 Check the synchronisation of the left and right carriage and check if there are any damage to parts, if there
is any fault, immediately cease operation and contact the authorised repairer.
4.2 Hoist layout
Before you install the hoist, you should check the following items:
4.2.1 The working area should be well designed and have enough space.
4.2.2 Avoid barrier like electric wire to the installiation area.
4.2.3 Check carefully if there is cracks to the concrete ground. Check if the strength of the concrete is per the
manufacturer's requirements. The compressive strength should be no less than than 425kg/cm. The thickness of
concrete basement should be no less than 200mm, the strength should be no less than 25-30 Mpa, the just finished
concrete basement must be solidified and cured over 28 days. Otherwise, this will cause damage to equipment or
injury & death.
4.2.4 The installation basement must assure certain levelness; the tolerance is not allowed over 5mm, the tolerance
within this limit can be adjusted byusing shims. If the ground is uneven, it must be re-pored to the correct
requirements.
4.2.5 Do not install equipment on asphalt or other non-concrete surface.
4.2.6 Do not install equipment on an uneven concrete surface.
4.2.7 Do not install equipment on a second or higher floor without the approval of an engineer.
4.2.8 Do not install the equipment outdoors, it will void the warranty.
4.2.9 Confirm the general installation position of the equipment, and then put columns and platform on their
respective places.
4.2.10 Confirm the location of the electric cabinet and keep enough space for operation.
4.2.11 Draw up the position of the baseboard of the column with chalk after the confirmation to assure the tolerance
within 3mm to avoid effecting the installation of the hoist.
4.2.12 Check carefully to assure the layout is correct.

OPERATING INSTRUCTIONS
The hoist should only be operated by personnel that have been thoroughly trained in
operation and maintenance of the hoist.
1. Drive top vehicle onto the elevating platform. Vehicles can be driven in nose first or backed in.
2. Drive until the top vehicle's forward tyres rest against the forward wheel stop.
3. Turn off car engine, engage safety brake, and place the vehicle's gear selector in Park. If vehicle is
manual transmission, place the transmission in first gear.
4. Check the front of the hoist to make sure that the vehicles forward tyres are securely set against the
wheel stop.
5. Walk around the hoist to ensure no obstructions will interfere with the vehicle being lifted.
6. Position yourself in front of the hoist within reach of the operator control console.
TO RAISE THE HOIST
1. Once all precautions above are followed, check around and above the hoist to ensure that no objects
hoist.
2. To raise the hoist platform, insert the key into the control console, turn the operator switch on the
control console to the left position and hold.
3. During operation, observe the entire perimeter of the hoist as well as overhead to ensure there are no
obstructions that may damage vehicle and / or the hoist.
4. ALWAYS raise the platform until it reaches its top custom-set lock position.
5. If a low ceiling is overhead be careful when lifting. NEVER allow the top vehicle to come in contact with
any overhead structure or object.
6. Once top position is reached, release the operator switch to its neutral position then push the center
button on the operator console, the hoist will then rest on the nearest lock position.
NOTE: Check for
correct engagement of each lock.
PLACEMENT OF LOWER VEHICLE
1. Once all precautions of the Pre-Lifting and Lifting Stage have been followed, drive the lower vehicle
under the hoist platform until the vehicle is correctly parked under the top platform, or, to the location
where the car is properly positioned under the hoist to allow clearance of the doors and mirrors.
2. Turn off the engine, set the parking brake and place the gear selector to Park, or place manual
transmission into first gear.
REMOVAL OF LOWER VEHICLE
1. Carefully drive out the lower vehicle after making sure all is clear before lowering the lift platform.
TO LOWER THE HOIST
1. Walk around the hoist to make sure nothing is below or near the hoist platforms entire lower area to
prepare for descent.
2. Be certain that no person (except the lift operator) is within 3 meters of the hoist area.
3.
Turn and hold the operator switch to the right position
NOTE: the hoist will automatically raise
approximately 50mm or enough to allow the mechanical locks to release.
4. The hoist will automatically stop and automatically start descending.
5. When lowering the hoist always be watchful for objects, persons or animals that may wander under the
hoist platform during operation. Cease operation by pressing the emergency stop on the control console
if area becomes obstructed.
6. KEEP HANDS AND FEET CLEAR OF ALL MOVING PARTS AND PINCH POINTS.
7. The top vehicle is now ready to be removed from the parking area. Turn the key to the off position on
the control console and remove.
