SAFETY WARNINGS

FIGURE 1 - LOCKOUT/TAGOUT

LOCKOUT/TAGOUT PROCEDURES

The Occupational Safety and Health Administration requires that, in addition to posting safety warnings and barricading

the work area, the power supply has been locked in the OFF position or disconnected. It is mandatory that an approved

lockout device is utilized. An example of a lockout device is illustrated. The proper lockout procedure requires that the

person responsible for the repairs is the only person who has the ability to remove the lockout device.

In addition to the lockout device, it is also a requirement to tag the power control in a manner that will clearly note that

repairs are under way and state who is responsible for the lockout condition. Tagout devices have to be constructed and

printed so that exposure to weather conditions or wet and damp locations will not cause the tag to deteriorate or become

unreadable.

RITE-HITE®Corporation does not recommend any particular lockout device, but recommends the utilization of an OSHA

approved device (refer to OSHA regulation 1910.147). RITE-HITE®Corporation also recommends the review and

implementation of an entire safety program for the Control of Hazardous Energy (Lockout/Tagout). These regulations are

available through OSHA publication 3120.

This is the highest level statement. Failure to

follow the listed instructions will most likely result in

severe injury or death.

This is a statement of serious hazard. Failure

to follow the listed instructions could place the

individual at risk of serious injury or death.

The statements used with this level of

warning deal with a safe operating

procedure. If the procedure is ignored, the

possibility of personal injury may exist.

IMPORTANT is used to draw attention

to a procedure that needs to be followed to prevent

machine or property damage.

When working with electrical or electronic controls,

make sure that the power source has been locked

out and tagged according to OSHA regulations and

approved local electrical codes.

on preceding page.

• Before starting installation or maintenance,

check and follow the safety procedures of the

facility where the LRL is being installed.

• Never enter a truck/trailer until its brakes are

set, air has been dumped from air ride

suspension (if applicable), and you have

visually inspected to be sure truck/trailer is

securely held in place by a vehicle restraint or

wheel chock per OSHA regulations.

• DO NOT operate with anyone under platform

or in front of the lip.

• Keep hands, limbs and loose hair clear of

equipment when operating. DO NOT wear

to store it with the platform fully lowered.

• If a malfunction does occur, always call your

authorized RITE-HITE®service representative

immediately.

Inspect the LRL monthly to ensure that there are no

broken or worn parts which could cause injury to

personnel or damage to the equipment.

PREPARATION PRIOR TO INSTALLATION

1. Elevating dock lift is shipped equipped with lifting lugs.

DO NOT remove until lift is resting in pit. (Lifting lugs

prevent the lift table from opening when the lift table is

lifted into place.)

2. Verify that dock lift voltage matches the voltage

supplied.

INSTALLATION INTO PIT

1. Clean out pit and remove all debris from work area.

2. Attach lifting chain to dock lift and position as close to

pit area as possible. See ﬁgure 4.

3. Disconnect hydraulic hoses from power unit. Feed

hydraulic hoses through conduit.

NOTE: Hydraulic hoses MUST BE protected from any

dirt or debris that could enter the system.

4. If equipped, disconnect wiring from power unit. Feed

wiring through conduit.

5. Lower the dock lift into the pit while pulling the

hydraulic hoses and wiring through the conduits.

6. Install hydraulic hoses to power unit and make

necessary connections.

ELECTRICAL INSTALLATION PROCEDURES

1. Position power unit adjacent to the dock position.

2. Secure power unit in accordance with all local

electrical codes.

3. Connect wiring as indicated by Electrical Schematics

located in the control box.

Control Box Installation Guidelines - Temperature

Controlled Applications.

a. Conduit should be routed to enter through the bottom

or side of the enclosure. A drip leg may be needed if

the conduit could ﬁll with water.

b. Seal the conduit in any location where the conduit

transitions temperature zones that may produce

condensation.

c. Spacers should be installed between the enclosure and

the wall to provide tempature insulation and air ﬂow.

INSTALLATION INSTRUCTIONS - CONT.

Make sure that the lift power has been locked out

and tagged out according to OSHA regulations and

approved local codes before performing any welding

on the dock lift or when working on electrical or

electronic controls.

Make sure that the lifting equipment is rated for 4,000

Lbs. - (5 / 6K), or 5,000 Lbs. - (8 / 10K) lifting capacity

or greater.

• Post safety warnings and barricade work area

to prevent unauthorized use of the elevating

dock lift while work is being performed.

• ALWAYS ground to the frame or pit angle

when welding. DO NOT ground welding

equipment to any electrical components. DO

NOT ground to lift platform when welding

on lift frame. Damage to bearings or

electrical components may result.

• DO NOT connect green ground lead into

control box or junction box until all welding is

complete.

• Protect Hydraulic Hose assemblies from

damage due to welding, grinding or sharp

objects.

• DO NOT position the dock lift on its side or

turn the dock lift topside down at any time.

• If a procedure is not clearly deﬁned in this

manual, contact your local representative or

RITE-HITE®at 1-800-456-0600 before

proceeding.
