COFFING MA & MAL Ratchet Lever Hoists 3/4 to 6 t

Check up to five results to perform an action.


FIVE SEALS PROTECT INTERNAL COMPONENTS
MA Model - Five Seals
Efficient hoist performance is assured by keeping moisture, oils, chemicals, and dirt out of the brake mechanism. Neoprene seals on the
(1) Handle cap,
(2) Load pawl shaft,
(3) Load sheave,
(4) Cover plate, and
(5) Gasket on the cover piate, provide protection under exposure conditions.

MAL Models - Overload Slip Clutch

The MAL slip clutch load limiting device protects the load, the operator, and the hoist by preventing the lifting of damaging overloads. The gradual slip mechanism prevents sudden, unexpected movement of the handle.

COFFING MA and MAL Models - Survive the toughest environments to provide safe, secure load control. Five seals (exclusive to the MA and MAL) increase the life of the hoist by protecting the gears and the brake mechanism from contamination by oil, grease, dirt, water, and other environmental hazards (see page 54). The MA and MAL are ideal for construction, industrial, and maintenance applications which require a brake for precise positioning or to disengage the tension on the load.

CAPACITIES & LIFT - Rated loads from 3/4 to 6 Tons, with 5-foot standard lift. Other lifts available.

RUGGED - Unit and handle made from high strength ductile aluminum alloy for corrosion resistance and portability.

FREE CHAINING MECHANISM - Allows quick and easy one-handed take-up and positioning of slack chain. Will not accidently free chain when under load.

FIVE SEALS - Keep the brake mechanism clean and dry, so braking performance remains consistent even under severe exposure conditions.

LOAD LIMITER (MAL Models) - See page 54.

PRECISE LOAD POSITIONING - Screw and disc brake lowering allows “microinching” for load spotting within fractions of an inch.

HANDLE STOPS - Keep handle from spinning in case operator’s hand accidently slips off the handle.

TOP SLING MODELS - Allow secure fastening around posts, beams, and other anchor points for easy rigging. MAR model has 30” sling with grab hook.

OPTIONS - Bullard hooks, bronze hooks, zinc-plated hooks, and zinc-plated chain - consult factory.
